How to split the filename from a full path in batch?

Parse a filename from the fully qualified path name (e.g., c:\temp\my.bat) to any component (e.g., File.ext).

Single line of code:

For %%A in ("C:\Folder1\Folder2\File.ext") do (echo %%~fA)

You can change out "C:\Folder1\Folder2\File.ext" for any full path and change "%%~fA" for any of the other options you will find by running "for /?" at the command prompt.

Elaborated Code

set "filename=C:\Folder1\Folder2\File.ext"
For %%A in ("%filename%") do (
    echo full path: %%~fA
    echo drive: %%~dA
    echo path: %%~pA
    echo file name only: %%~nA
    echo extension only: %%~xA
    echo expanded path with short names: %%~sA
    echo attributes: %%~aA
    echo date and time: %%~tA
    echo size: %%~zA
    echo drive + path: %%~dpA
    echo name.ext: %%~nxA
    echo full path + short name: %%~fsA)

Standalone Batch Script
Save as C:\cmd\ParseFn.cmd.

Add C:\cmd to your PATH environment variable and use it to store all of you reusable batch scripts.

@echo ParseFn parses a fully qualified path name (e.g., c:\temp\my.bat)
@echo into the requested component, such as drive, path, filename, 
@echo extenstion, etc.
@echo.
@echo Syntax: /switch filename
@echo where,
@echo   filename is a fully qualified path name including drive, 
@echo   folder(s), file name, and extension
@echo.
@echo   Select only one switch:
@echo       /f - fully qualified path name
@echo       /d - drive letter only
@echo       /p - path only
@echo       /n - file name only
@echo       /x - extension only
@echo       /s - expanded path contains short names only
@echo       /a - attributes of file
@echo       /t - date/time of file
@echo       /z - size of file
@echo      /dp - drive + path
@echo      /nx - file name + extension
@echo      /fs - full path + short name

But I can't take credit for this; Google found this at http://www.dostips.com/forum/viewtopic.php?f=3&t=409

Continuing from Pete's example above, to do it directly in the cmd window, use a single %, eg:

cd c:\test\folder A
for %X in (*)do echo %~nxX

(Note that special files like desktop.ini will not show up.)

It's also possible to redirect the output to a file using >>:

cd c:\test\folder A
for %X in (*)do echo %~nxX>>c:\test\output.txt

For a real example, assuming you want to robocopy all files from folder-A to folder-B (non-recursively):

cd c:\test\folder A
for %X in (*)do robocopy . "c:\test\folder B" "%~nxX" /dcopy:dat /copyall /v>>c:\test\output.txt

and for all folders (recursively):

cd c:\test\folder A
for /d %X in (*)do robocopy "%X" "C:\test\folder B\%X" /e /copyall /dcopy:dat /v>>c:\test\output2.txt
