# Truename

Displays the true DOS path in 8.3 format corresponding to the long filename current path and/or virtual drives created using the SUBST command.

## Syntax:

To display the full path (in short file name form) of the current directory of any drive:
TRUENAME [drive:]

To display the full path (in short file name form) of a file in the current directory of any drive:
TRUENAME [drive:] file.ext

To display the full path (in short file name form) of a drive created with SUBST:
TRUENAME substdrive:

where file.ext is an existing file name in 8.3 form.

## Notes:

1. Although TRUENAME will return output when used other than the above, my testing indicates such output is likely bogus (and not reliable).

2. This command is undocumented and first publicised (as far as I know) in a letter from W. Dnes in PC Magazine (Oct.16, 1990, p491)

## Example:

1. If "c:\program files\microsoft office\office" has been assigned to drive O: using the SUBST command, then entering:
TRUENAME O:
would result in something like:
C:\PROGRA~1\MICROS~3\OFFICE
where C:\PROGRA~1\MICROS~3\OFFICE is the path in 8.3 form assigned to drive O:

2. If "c:\program files\microsoft office\office" should be the current directory on c: and you are working in the d: drive, then the truename of "c:\program files\microsoft office\office\substitution1.txt" would be given by:
TRUENAME c:substi~1.txt
Note: TRUENAME c:substitution1.txt would result in a "file not found" error message.
