Mapping local folder as new logical drive

Hi,

For some of my old code to work, I need a D: drive.
Unfortunately my new laptop only has one partition,
so I mapped the ABC folder on my C: drive(C:\ABC)
as a logical D: drive. My ABC folder is shared as ABC$
I am running XP.

I mapped network drive D: via explorer > tools > map network drive
using

\\127.0.0.1\ABC$

This works fine, I can access that drive correctly as long as my laptop is on the LAN.
When I disconnect the laptop from te LAN, and try to access the logical D: drive
I get :

"An error occurred while reconnecting D: to \\127.0.0.1\ABC$
Microsoft Windows Network : the local device name is already in use"

This probably has to do with my network bridge no longer being active..

I tried to solve my issue by selecting the "Make Available Offline"
option on the D: drive and synchronising, but still after disconnecting from
the LAN I get the the local device name is already in use error.

Any ideas?

Yeah, try the old fashioned method. There is a DOS command called SUBST which allows you to have a drive letter point at a folder on your hard drive.

Start Menu, Run, type in CMD and hit enter

SUBST D: C:\ABC

Will do the trick. Put this in a batch file and put the batch file in the startup group.

Or put in in AUTOEXEC.NT (lives in C:\WINDOWS\SYSTEM32, or C:\WINNT\SYSTEM32)

Regards,

Joe

sorry for the late reply, work kept me busy :->
For the extra 25, could you also give me the command to disconnect the drive.
Thanks a lot,

To delete a SUBST drive, type in:

SUBST X: /d

If you ever want to know syntax for any DOS command, just type in the command and a /?:

SUBST /?

This gives the following output:

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.






Hope this helps!

Regards,

Joe

Hey guys-

I am trying the same thing here, only the SUBST command seems to follow the old 8.3 file names.

I am entering the command: subst x: c:\program files\test

and I get: Incorrect number of parameters - files.  
Other "shorter" directories work fine.

I am trying to automate a directory update using a batch file and the receiving directory is
nested in the "Program files" folder.

Thanks in advance,

Lance

Simple, although if I were a nasty Expert I'd tell you to post your own question ;-)

A lot of dos commands cannot cope with spaces in file or folder names, so you use inverted commas to deal with the space. You typed:

 subst x: c:\program files\test

As far as the DOS command is concerned, the folder to SUBST is C:\program and you've passed files\test as another parameter.

 subst x: "c:\program files\test"

The inverted commas wrap up the whole C:\program files\test statement as one parameter. That is, SHIFT key and press number 2 (I'm assuming a UK keyboard, US keyboard it's SHIFT + apostrophe key I think). It isn't two apostrophes or anything like that.
