Get full path and long file name from short file name

Question

I have an nice console file manager (eXtreme by Senh Liu), it passes short path/filenames as variables to a menu.bat.

How can I generate a full folder name + long fi

Answer 1

@echo off
setlocal
rem this need to be a short name to avoid collisions with dir command bellow
cd C:\BALBAL~1\BLBALB~1\
set "curr_dir=%cd%"
set "full_path="

:repeat

for /f "delims=" %%f in ('for %%d in ^(.^) do @dir  /a:d /n /b "..\*%%~snd"') do ( 
    set "full_path=%%f\%full_path%"
)

cd ..

if ":\" NEQ "%cd:~-2%" (
    goto :repeat
) else (
    set "full_path=%cd%%full_path%"
)

echo --%full_path%--
cd %curr_dir%
endlocal

The path is hardcoded at the beginning but you can change it or parameterizied it.As you can easy get the full name of a file here is only a solution for directories.

EDIT

now works for file and directory and a parameter can be passed:

   @echo off

rem ---------------------------------------------
rem ---------------------- TESTS ----------------
rem ----------------------------------------------

md "c:\test\blablablablabl\bla bla bla\no no no no no no\yes yes yes" >nul 2>&1
md "c:\test\1                      b1\1\" >nul 2>&1
for %%t in ("c:\test\blablablablabl\bla bla bla\no no no no no no\yes yes yes") do set t_dir=%%~st
for %%t in ("c:\test\1                      b1\1\") do set t_dir2=%%~st
echo a>"%t_dir2%a"
echo a>"%t_dir2%a a.txt"

echo testing "%t_dir%\\"
call :get_full_name "%t_dir%\\"
echo(
echo testing "%t_dir2%a"
call :get_full_name "%t_dir2%a"
echo(
echo testing "%t_dir2%a a.txt" with return variable
call :get_full_name  "%t_dir2%a a.txt" test_var
echo  return variable : -- %test_var% --
goto :eof

rem -------------------------------------

:get_full_name [%1 - short path to a file or directory ; %2 - if set stores the result in variable with that name] 
setlocal
if not exist "%~1" ( echo file/dir does not exist & exit /b 2 )

set "curr_dir=%cd%"
for /f "delims=" %%n  in ('dir /b /n "%~dps1\%~snx1"') do set "name=%%n"

cd "%~dps1"
set "full_path="
:repeat
for /f "delims=" %%f in ('for %%d in ^(.^) do @dir  /a:d /n /b "..\*%%~snd"') do ( 
    set "full_path=%%~f\%full_path%"
)
cd ..
if ":\" NEQ "%cd:~-2%" (
    goto :repeat
) else (
    set "full_path=%cd%%full_path%"
)

echo %full_path%%name%
cd %curr_dir%
endlocal & if "%~2" NEQ ""  set "%~2=%full_path%%name%"

and the test output:

testing "c:\test\BLABLA~1\BLABLA~1\NONONO~1\YESYES~1\\"
c:\test\blablablablabl\bla bla bla\no no no no no no\yes yes yes\

testing "c:\test\1B1~1\1\a"
c:\test\1                      b1\1\a

testing "c:\test\1B1~1\1\a a.txt" with return variable
c:\test\1                      b1\1\a a.txt
 return variable : -- c:\test\1                      b1\1\a a.txt --

Answer 2

My solution:

set shortname=P:\MYPROG~1\SHELLS\ZBACKUP\REFSTO~1.BAL
for /F %f in ('dir /b /s %shortname%') do where /R %~dpf %~nf%~xf

if you use it in a batch file:

for /F %%f in ('dir /b /s %shortname%') do where /R %%~dpf %%~nf%%~xf

Answer 3

Simple solution: use PowerShell.

PS C:\> (Get-Item 'P:\MYPROG~1\SHELLS\ZBACKUP\REFSTO~1.BAL').FullName
P:\MyPrograms\SHELLS\zBackup\RefsToMyData.bal

You can incorporate a PowerShell call in a batch file like this:

@echo off

setlocal

for /f "usebackq delims=" %%f in (
  `powershell.exe -Command "(Get-Item '%~1').FullName"`
) do @set "var=%%~f"

echo %var%

Output:

C:\> test.cmd P:\MYPROG~1\SHELLS\ZBACKUP\REFSTO~1.BAL
P:\MyPrograms\SHELLS\zBackup\RefsToMyData.bal

PowerShell is available for all supported Windows versions:

• Windows XP SP3 and Server 2003 SP2: PowerShell v2 available
• Windows Vista and Server 2008: ship with PowerShell v1 (not installed by default), PowerShell v2 available
• Windows 7 and Server 2008 R2: PowerShell v2 preinstalled, PowerShell v3 available (batteries not included)
• Windows 8 and Server 2012: PowerShell v3 preinstalled

If PowerShell can't be used for some reason (e.g. administrative restrictions), I'd use VBScript instead:

name = WScript.Arguments(0)

Set fso = CreateObject("Scripting.FileSystemObject")
If fso.FileExists(name) Then
  Set f = fso.GetFile(name)
ElseIf fso.FolderExists(name) Then
  Set f = fso.GetFolder(name)
  If f.IsRootFolder Then
    WScript.Echo f.Path
    WScript.Quit 0
  End If
Else
  'path doesn't exist
  WScript.Quit 1
End If

Set app = CreateObject("Shell.Application")
WScript.Echo app.NameSpace(f.ParentFolder.Path).ParseName(f.Name).Path

A VBScript like the one above can be used in a batch file like this:

@echo off & setlocal

for /f "delims=" %%f in ('cscript //NoLogo script.vbs "%~1"') do @set "var=%%~f"

echo %var%

This does require an additional script file, though.

Answer 4

This returns the full long pathname, but depends on:
A) there not being too many files in the tree (due to time taken)
B) there is only one of the target (long) filename in the tree.

@echo off
for /f "delims=" %%a in (' dir /b "%~1" ') do set "file=%%a"
for /f "delims=~" %%a in ("%~dp1") do cd /d "%%a*"
for /f "delims=" %%a in ('dir /b /s /a-d "%file%" ') do set "var=%%a"
echo "%var%"

When called with mybat "d:\MYPROG~1\SHELLS\zBackup\REFSTO~1.BAL"
it returned this:

"d:\MyPrograms\SHELLS\zBackup\RefsToMyData.bal"
