Batch Extract path and filename from a variable

Question

How can I extract path and filename from a variable?

Setlocal EnableDelayedExpansion
set file=C:\Users\l72rugschiri\Desktop\fs.cfg

I want to do that without using any function or any GOTO. is it possible?

Answer 1

@ECHO OFF
SETLOCAL
set file=C:\Users\l72rugschiri\Desktop\fs.cfg
FOR %%i IN ("%file%") DO (
ECHO filedrive=%%~di
ECHO filepath=%%~pi
ECHO filename=%%~ni
ECHO fileextension=%%~xi
)

Not really sure what you mean by no "function"

Obviously, change ECHO to SET to set the variables rather thon ECHOing them...

See for documentation for a full list.

ceztko's test case (for reference)

@ECHO OFF
SETLOCAL
set file="C:\Users\ l72rugschiri\Desktop\fs.cfg"
FOR /F "delims=" %%i IN ("%file%") DO (
ECHO filedrive=%%~di
ECHO filepath=%%~pi
ECHO filename=%%~ni
ECHO fileextension=%%~xi
)

Answer 2

You can only extract path and filename from (1) a parameter of the BAT itself %1, or (2) the parameter of a CALL %1 or (3) a local FOR variable %%a.

---

in HELP CALL or HELP FOR you may find more detailed information:

%~1 - expands %1 removing any surrounding quotes (")
%~f1 - expands %1 to a fully qualified path name
%~d1 - expands %1 to a drive letter only
%~p1 - expands %1 to a path only
%~n1 - expands %1 to a file name only
%~x1 - expands %1 to a file extension only
%~s1 - expanded path contains short names only
%~a1 - expands %1 to file attributes
%~t1 - expands %1 to date/time of file
%~z1 - expands %1 to size of file

---

And then try the following:

Either pass the string to be parsed as a parameter to a CALL

call :setfile ..\Desktop\fs.cfg
echo %file% = %filepath% + %filename%
goto :eof

:setfile
set file=%~f1
set filepath=%~dp1
set filename=%~nx1
goto :eof

or the equivalent, pass the filename as a local FOR variable

for %%a in (..\Desktop\fs.cfg) do (
    set file=%%~fa
    set filepath=%%~dpa
    set filename=%%~nxa
)    
echo %file% = %filepath% + %filename%
