How to make SUBST mapping persistent across reboots?












159















Does Windows (XP or later) have a built-in way to create persitent drive mappings, like the ones SUBST creates? I found a 3rd party tool psubst. Is there a way to do it without 3rd party tools?

  • It is possible, because psubst is just a .bat file that mucks with the registry. See @davr's answer below for details.

  • Caveat from the Wikipedia article in the accepted answer: "Starting with Windows Vista, deleted files are immediately deleted permanently, and are not moved to the "Recycle Bin". Prior to Windows Vista (in Windows XP, for example) files from substituted "disks" were moved to the Recycle Bin when deleted."

    @IvoFlipse, that's a good assumption in general but in this case it's just wrong. The '3rd party tool' is a 150 line batch file that provides a nice cli for modifying a registry and cleaning input to comply with subst's picky trailing slash rules, but it's just a pretty wrapper. You can do it without a program, and the README for psubst explains how. Or, see davr's answer below where he quotes the psubst README.

Well Wikipedia mentions:




C:>SUBST /?
Associates a path with a drive letter.

SUBST [drive1: [drive2:]path]
SUBST drive1: /D

drive1: Specifies a virtual drive to which you want to assign a path.
[drive2:]path Specifies a physical drive and path you want to assign to
a virtual drive.
/D Deletes a substituted (virtual) drive.

Type SUBST with no parameters to display a list of current virtual drives.



So you can associate paths with drive letters using subst. The Persistent SUBST command (psubst) software seems to be darn handy, and they provide a solution to run it from startup:



https://code.google.com/p/psubst/#Inconstancy




Inconstancy



However restart of a system destroys a virtual disk. What to do? A
disk can be created after startup. But what to do, when a disk is
needed on early steps of a startup? For example, to run services?
There is system feature to start a virtual disk from the system
registry:



REGEDIT4 

[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerDOS Devices]
"Z:"="\??\C:\Documents and Settings\All Users\Shared Documents"


It is enough to create a text file with the extension .REG and run
it. When the next starting up of a system, the virtual disk will be
exist at logon. It needs to define a name of disk and path. Note that
each backslash in the path is doubled.




In Windows, you can run the registry editor as follows:





  1. Start » Run... (or hit Win+R)

  2. Type: regedit

  3. In Windows Vista and above, UAC will pop up, click "Yes".

    Nice to know, even though I don't use subst anymore. But back in the times when I did I used to simply have a batch file sitting in my Startup folder which did those things.

    This is awesome. (It requires a reboot, FYI.) Our source tree has to start from a specific drive letter so that our PDBs all always align on different computers. This registry setting solves an annoyance that I have had for years with a subst disk not being there with runas which is a big annoyance if you need to (rarely) run Visual Studio under an admin account.

    Thanks for the solution. FYI, if you type the variable into RegEdit interactively, do not double the backslashes. That is, create a new string variable named "Z:" (without the quotes) and set the value to the string shown above except with single backslashes.

    @Devil'sAdvocate, ?? is a virtual directory in the NT object manager namespace. First it checks the logon session DOS 'devices' (really DOS devices are symbolic links to NT devices, usually located in Device) and then the Global?? DOS devices. In WinObj you'll find the logon session devices in SessionsDosDevices[logon ID]. Notice that logon session devices are all tracked in session 0 (services) for each LSA logon ID. They aren't correlated with desktop sessions. That's why if you map a drive as a limited admin it doesn't exist when elevated; it's a different logon.

Installing it at HKEY_CURRENT_USER has the benefit of having different setups for each user. I prefer to stick the user space setup as long as a system service dose not depend on the device.



REGEDIT4
[HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun]
"F Drive"="subst F: D:\mount\db"
"G Drive"="subst G: D:\mount\log"

    Can also do this from the command line (since XP/Windows 2000 server): reg add HKCUSOFTWAREMicrosoftWindowsCurrentVersionRun /v "F Drive" /d "subst F: D:xdb" NB only needs escaping here if it is the last character of the subst command, e.g. when the target is the root directory: "subst F: D:\"; a single there would be interpreted as escaping the " following it.

There's an answer in the page you linked to. You don't need the third party tool, you can do it with a simple registry entry, as detailed on that page.



Create a text file named 'mapdrive.reg' with these contents:



REGEDIT4 

[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerDOS Devices]
"Z:"="\??\C:\Documents and Settings\All Users\Shared Documents"


Then should just be able to double-click on it to set up, no 3rd party tools needed.

    the advantage to the reg key versus the batch file is that it sets the subst drive before any other startup commands run, in case some of those need the subst drive to function

I found this because I was looking for an improvement over my startup subst scripts - they worked OK, but sometimes executed after folders crashed on startup because my drive wasn't yet mapped.



First, I edited the registry, but was unable to get it to work. However, I did come across this alternative, which although it doesn't use subst does answer for me the question, "How to make SUBST mapping persistent across reboots?" Don't use subst... (insert appropriate 'computerName' and 'pathName'):



net use u: "\computerNamec$pathName" /persistent:yes


I adapted this from Hank Arnold's suggestion at this discussion of mapping local drives. I had guessed that \myComputerNamec might work, but I didn't know to apply the $.



Before you try the "net use" command, try to navigate to


\computerNamec$
to make sure you have 'computerName' correct.

    Excellent solution, albeit with two problems: 1) it's not visible to the local file-system, 2) permissions...

    if you use \localhostc$pathtothing it is portable across machines (or upgrades that change the computer name). A drawback of using a mapped drive on Win7+ is that different security policies apply to network drives than local, and some programs will just refuse to run off a mapped drive.

    It is visible to the file system, and it is visible to the local file system -- it's marked as a network drive, just as some drives are marked as removeable drives. That doesn't make such drives not a part of, or not visible to, the local file system -- it makes them network/removable drives in the local file system.

    In testing I did for a performance issue (a couple of years back now) using the (locally) mounted network drive is also slower than using the file system (or subst etc.) directly. This is not a tremendous difference for small files or occasional use -- not like going over the actual network to another 'server' -- but it is significant.

Drop a batch file in your Startup folder that does all the SUBSTs that you want to do.

    Since the original PSubst has some limitations and seems to be concluded by the author, I had to code a new version for my needs, fixing some problems and adding functionality and flexibility.



    Check here for PSubst version 3 batch file



    https://github.com/cyberponk/psubst



    Compatible with Windows 7, Windows 8, Windows 10, Windows Server 2012



    Note:
    This work has no intention of demeriting the original author and only came to existence because of real necessity, as follows:




    • As a newtork admin I have the constant need for SUBST´ing network drives and fiddling with different network users.


    • As not everyone is a Windows expert, i figured the automatic admin elevation with error handling would help, based on coments I read through the web.


    • As some people struggled with the arguments order, I figured it would be best for the script to work with arguments in any order.



    I can´t recall of every added functionality, but every inclusion was done purely by necessity. I am sharing the code so that others may not encounter the troubles I had. By this there is no intention other than sharing and helping.

    • Please, saying "A" say "B". You've siac that the original psubst has a lot of problem - please point on them if they are. On the other hand, psubst is not abandoned. It's just achieved the limit of its development. The original tool follows very simple philosophy: do something and do well. It is not overloaded with extra functionality like handling with UAC and creating additional vbs-code for doing something more. One thing can be done over the original code - some cosmetic changes to simplifing the code and improve readability.

      – jsxt
      Feb 29 '16 at 6:33











    • Editted, please review. UAC and vbs is for automatic admin elevation. I disagree on the "limit of development" comment, as all changes I made were to make the use even more simple and easy after I encountered several problems using PSUBST. I do not intend to criticise the original author, so I will not list problems, but instead I created solutions. I actually proposed to add my editions in the original github branch, but got refused, so I had to create my own branch.

    Actually, the PSUBST tool joins two different ways of creation of substituted drives in Windows. If you want to have persistent drives between startups then you can run this tool once per each drive that you need. Another way is to use the method suggested by "davr". the PSUBST tool just makes the same but allows to make it in the easier way.

        REGEDIT4 

        [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerDOS Devices]
        "Z:"="\??\C:\Documents and Settings\All Users\Shared Documents"


        It is enough to create a text file with the extension .REG and run
        it. When the next starting up of a system, the virtual disk will be
        exist at logon. It needs to define a name of disk and path. Note that
        each backslash in the path is doubled.




        In Windows, you can run the registry editor as follows:





        1. Start » Run... (or hit Win+R)

        2. Type: regedit

        3. In Windows Vista and above, UAC will pop up, click "Yes".

          Nice to know, even though I don't use subst anymore. But back in the times when I did I used to simply have a batch file sitting in my Startup folder which did those things.

          This is awesome. (It requires a reboot, FYI.) Our source tree has to start from a specific drive letter so that our PDBs all always align on different computers. This registry setting solves an annoyance that I have had for years with a subst disk not being there with runas which is a big annoyance if you need to (rarely) run Visual Studio under an admin account.

          @Devil'sAdvocate, ?? is a virtual directory in the NT object manager namespace. First it checks the logon session DOS 'devices' (really DOS devices are symbolic links to NT devices, usually located in Device) and then the Global?? DOS devices. In WinObj you'll find the logon session devices in SessionsDosDevices[logon ID]. Notice that logon session devices are all tracked in session 0 (services) for each LSA logon ID. They aren't correlated with desktop sessions. That's why if you map a drive as a limited admin it doesn't exist when elevated; it's a different logon.

        Well Wikipedia mentions:




        C:>SUBST /?
        Associates a path with a drive letter.

        SUBST [drive1: [drive2:]path]
        SUBST drive1: /D

        drive1: Specifies a virtual drive to which you want to assign a path.
        [drive2:]path Specifies a physical drive and path you want to assign to
        a virtual drive.
        /D Deletes a substituted (virtual) drive.

        Type SUBST with no parameters to display a list of current virtual drives.



        So you can associate paths with drive letters using subst. The Persistent SUBST command (psubst) software seems to be darn handy, and they provide a solution to run it from startup:



        https://code.google.com/p/psubst/#Inconstancy




        Inconstancy



        However restart of a system destroys a virtual disk. What to do? A
        disk can be created after startup. But what to do, when a disk is
        needed on early steps of a startup? For example, to run services?
        There is system feature to start a virtual disk from the system

        Can also do this from the command line (since XP/Windows 2000 server): reg add HKCUSOFTWAREMicrosoftWindowsCurrentVersionRun /v "F Drive" /d "subst F: D:xdb" NB only needs escaping here if it is the last character of the subst command, e.g. when the target is the root directory: "subst F: D:\"; a single there would be interpreted as escaping the " following it.

        There's an answer in the page you linked to. You don't need the third party tool, you can do it with a simple registry entry, as detailed on that page.



        Create a text file named 'mapdrive.reg' with these contents:



        REGEDIT4 

        [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerDOS Devices]
        "Z:"="\??\C:\Documents and Settings\All Users\Shared Documents"


        Then should just be able to double-click on it to set up, no 3rd party tools needed.

          the advantage to the reg key versus the batch file is that it sets the subst drive before any other startup commands run, in case some of those need the subst drive to function

        I found this because I was looking for an improvement over my startup subst scripts - they worked OK, but sometimes executed after folders crashed on startup because my drive wasn't yet mapped.



        First, I edited the registry, but was unable to get it to work. However, I did come across this alternative, which although it doesn't use subst does answer for me the question, "How to make SUBST mapping persistent across reboots?" Don't use subst... (insert appropriate 'computerName' and 'pathName'):



        net use u: "\computerNamec$pathName" /persistent:yes


        I adapted this from Hank Arnold's suggestion at this discussion of mapping local drives. I had guessed that \myComputerNamec might work, but I didn't know to apply the $.



        Before you try the "net use" command, try to navigate to


        \computerNamec$
        to make sure you have 'computerName' correct.

          if you use \localhostc$pathtothing it is portable across machines (or upgrades that change the computer name). A drawback of using a mapped drive on Win7+ is that different security policies apply to network drives than local, and some programs will just refuse to run off a mapped drive.

          In testing I did for a performance issue (a couple of years back now) using the (locally) mounted network drive is also slower than using the file system (or subst etc.) directly. This is not a tremendous difference for small files or occasional use -- not like going over the actual network to another 'server' -- but it is significant.

                Since the original PSubst has some limitations and seems to be concluded by the author, I had to code a new version for my needs, fixing some problems and adding functionality and flexibility.



                Check here for PSubst version 3 batch file



                https://github.com/cyberponk/psubst



                Compatible with Windows 7, Windows 8, Windows 10, Windows Server 2012



                Note:
                This work has no intention of demeriting the original author and only came to existence because of real necessity, as follows:




                • As a newtork admin I have the constant need for SUBST´ing network drives and fiddling with different network users.


                • As not everyone is a Windows expert, i figured the automatic admin elevation with error handling would help, based on coments I read through the web.


                • As some people struggled with the arguments order, I figured it would be best for the script to work with arguments in any order.



                I can´t recall of every added functionality, but every inclusion was done purely by necessity. I am sharing the code so that others may not encounter the troubles I had. By this there is no intention other than sharing and helping.






                share|improve this answer


























                • Please, saying "A" say "B". You've siac that the original psubst has a lot of problem - please point on them if they are. On the other hand, psubst is not abandoned. It's just achieved the limit of its development. The original tool follows very simple philosophy: do something and do well. It is not overloaded with extra functionality like handling with UAC and creating additional vbs-code for doing something more. One thing can be done over the original code - some cosmetic changes to simplifing the code and improve readability.

                • Editted, please review. UAC and vbs is for automatic admin elevation. I disagree on the "limit of development" comment, as all changes I made were to make the use even more simple and easy after I encountered several problems using PSUBST. I do not intend to criticise the original author, so I will not list problems, but instead I created solutions. I actually proposed to add my editions in the original github branch, but got refused, so I had to create my own branch.

                Since the original PSubst has some limitations and seems to be concluded by the author, I had to code a new version for my needs, fixing some problems and adding functionality and flexibility.



                Check here for PSubst version 3 batch file



                https://github.com/cyberponk/psubst



                Compatible with Windows 7, Windows 8, Windows 10, Windows Server 2012



                Note:
                This work has no intention of demeriting the original author and only came to existence because of real necessity, as follows:




                • As a newtork admin I have the constant need for SUBST´ing network drives and fiddling with different network users.


                • As not everyone is a Windows expert, i figured the automatic admin elevation with error handling would help, based on coments I read through the web.


                • As some people struggled with the arguments order, I figured it would be best for the script to work with arguments in any order.



                I can´t recall of every added functionality, but every inclusion was done purely by necessity. I am sharing the code so that others may not encounter the troubles I had. By this there is no intention other than sharing and helping.

                • Please, saying "A" say "B". You've siac that the original psubst has a lot of problem - please point on them if they are. On the other hand, psubst is not abandoned. It's just achieved the limit of its development. The original tool follows very simple philosophy: do something and do well. It is not overloaded with extra functionality like handling with UAC and creating additional vbs-code for doing something more. One thing can be done over the original code - some cosmetic changes to simplifing the code and improve readability.

                • Editted, please review. UAC and vbs is for automatic admin elevation. I disagree on the "limit of development" comment, as all changes I made were to make the use even more simple and easy after I encountered several problems using PSUBST. I do not intend to criticise the original author, so I will not list problems, but instead I created solutions. I actually proposed to add my editions in the original github branch, but got refused, so I had to create my own branch.

                Actually, the PSUBST tool joins two different ways of creation of substituted drives in Windows. If you want to have persistent drives between startups then you can run this tool once per each drive that you need. Another way is to use the method suggested by "davr". the PSUBST tool just makes the same but allows to make it in the easier way.
