Below you will find two scripts that can be used to process multiple files (or even folders) by dragging and dropping them onto a batch script.
::Dragdrop.cmd @echo off :: Use this code stub as the basis for drag drop batch files :: You can drag and drop multiple files (or folders) :: If files are dropped it will return the long pathname of each file. :: If folders are dropped it will return the long pathname of :: each folder (but not the files in those folders) PUSHD %~dp0 IF NOT EXIST short2long.cmd ECHO Error&pause&GOTO :s_end :s_next IF ["%1"] EQU [""] GOTO :eof CALL short2long %1 :: At this point ECHO %v_short2Long% :: will display the long pathname of the current file ECHO %v_short2Long% :: Add other commands here SHIFT GOTO :s_next :s_end POPD
This second script Short2Long.cmd is called by the first and converts each short filename into a long one. (Place both scripts in the same folder)
:: short2Long.cmd @echo off SETLOCAL :: Converts short filename to long IF NOT exist %1 ECHO No such file or folder&goto :eof SET v_filename=%~nx1 SET v_ext=%~x1 SET v_remainder=%~dp1 IF defined v_ext echo ::File with extension&set v_fileYN=Y&goto :s_known_type IF NOT defined v_filename echo ::Path with trailing \ &goto :s_known_type DIR /a:d %1 >nul 2>&1 IF [%errorlevel%] EQU  Echo ::File without extension&set v_fileYN=Y&goto :s_known_type Echo ::Path without trailing \ :: so we need to fix the ~dp1 variable and add a trailing \ SET v_remainder=%v_remainder%%v_filename%\ echo. :s_known_type SET v_filename SET v_ext SET v_remainder :s_getnode FOR /f "tokens=1* delims=\" %%G IN ("%v_remainder%") DO set v_node=%%G&set v_remainder=%%H :: Store the drive letter IF "%v_node:~1,1%"==":" SET v_drive=%v_node%&goto :s_getnode ::Find the long filename equivalent for this node FOR /f "tokens=4* delims= " %%G in ( 'dir /x /a:d "%v_drive%%v_long_path%\%v_node%\.." ^| find "/"' ) DO call :s_process_node %%G "%%H" IF defined v_remainder GOTO :s_getnode :: At this point %v_long_path% is the long path :: and %v_filename% is the short filename :: Add the drive letter SET v_long_path=%v_drive%%v_long_path% :: Finally add the long filename to the path IF not defined v_fileYN GOTO :s_finish FOR /f "tokens=* delims= " %%G IN ('dir /b "%v_long_path%\%v_filename%"') DO ( SET v_long_path=%v_long_path%\%%G) GOTO :s_finish :s_process_node :: Now %1 is short filename and %2 is long filename(if there is one) :: Next line makes sure we have an exact match IF /i ["%v_node%"] NEQ ["%1"] goto :eof SET v_shortnode=%1 SET v_longnode=%2 :: If node is actually 8.3 - dir/x won't include a long filename so IF [%v_longnode%] EQU [""] SET v_longnode=%v_shortnode%&goto :s_store_node :: Remove quotes SET v_longnode=###%v_longnode%### SET v_longnode=%v_longnode:"###=% SET v_longnode=%v_longnode:###"=% SET v_longnode=%v_longnode:###=% :s_store_node :: Store this node SET v_long_path=%v_long_path%\%v_longnode% GOTO :eof :s_finish ECHO. ECHO short path is %1 ECHO long path is %v_long_path% PAUSE ENDLOCAL&set v_short2Long=%v_long_path%
This works for files with or without a file extension: FILE or FILE.TXT
However drag and drop of a folder won't work if the folder has an extension: MYFOLDER.BAD
It is possible that filenames with some puctuation characters may cause the script to fail.
