In case the file your variable holds doesn't actually exist the FOR approach won't work. One trick you could use, if you know the length of the extension, is taking a substring:

%var:~0,-4%

the -4 means that the last 4 digits (presumably .ext) will be truncated.

This is a really late response  but I came up with this to solve a particular problem I had with DiskInternals LinuxReader appending   efs ntfs  to files that it saved to non-NTFS  FAT32  directories     echo off REM  1 is the directory to recurse through and  2 is the file extension to remove for  R   1    f in     2  do       REM Path  sans drive  is given by    pf   drive is given by    df     REM file name  sans ext  is given by    nf   to  rename  files  move them     copy     df   pf   nf  2      df   pf   nf      echo     df   pf   nf  2  copied to     df   pf   nf  echo    pause

Without looping I am using this if I simply want to strip the extension from a filename or variable  without listing any directories or existing files   for   f in   quot  filename  quot   do set filename    nf  If you want to strip the extension from a full path  use   dpnf instead  for   f in   quot  path  quot   do set path    dpnf  Example   Use directly in the console   for  f in   quot file name dat quot   do  echo   nf  for  f in   quot C  Dir file dat quot   do  echo   dpnf  OUTPUT   file name C  Dir file

You can use    nf to get the filename only as described in the reference for for    echo off     for  R  C  Users Admin Ordner    f in    flv  do       echo    nf   pause   The following options are available    Variable with modifier  Description    I                     Expands  I which removes any surrounding                          quotation marks         fI                    Expands  I to a fully qualified path name    dI                    Expands  I to a drive letter only    pI                    Expands  I to a path only    nI                    Expands  I to a file name only    xI                    Expands  I to a file extension only    sI                    Expands path to contain short names only    aI                    Expands  I to the file attributes of file    tI                    Expands  I to the date and time of file    zI                    Expands  I to the size of file     PATH I               Searches the directories listed in the PATH environment                          variable and expands  I to the fully qualified name of                          the first one found  If the environment variable name is                          not defined or the file is not found by the search                          this modifier expands to the empty string

If your variable is an argument  you can simply use   dpn  for paths  or   n  for names only  followed by the argument number  so you don t have to worry for varying extension lengths  For instance   dpn0 will return the path of the batch file without its extension    dpn1 will be  1 without extension  etc  Whereas   n0 will return the name of the batch file without its extension    n1 will be  1 without path and extension  etc
