run cmd.exe and do the following:

> cd "long path name"
> command

Then command.com will come up and display only short paths.

source

for %I in (.) do echo %~sI

Any simpler way?

You could also enter the following into a CMD window:

dir <ParentDirectory> /X

Where <ParentDirectory> is replaced with the full path of the directory containing the item you would like the name for.

While the output is not a simple as Timbo's answer, it will list all the items in the specified directory with the actual name and (if different) the short name.

If you do use for %I in (.) do echo %~sI you can replace the . with the full path of the file/folder to get the short name of that file/folder (otherwise the short name of the current folder is returned).

Tested on Windows 7 x64.

In windows batch scripts, %~s1 expands path parameters to short names. Create this batch file:

@ECHO OFF
echo %~s1

I called mine shortNamePath.cmd and call it like this:

c:\>shortNamePath "c:\Program Files (x86)\Android\android-sdk"
c:\PROGRA~2\Android\ANDROI~1

Edit: here's a version that uses the current directory if no parameter was supplied:

@ECHO OFF
if '%1'=='' (%0 .) else echo %~s1

Called without parameters:

C:\Program Files (x86)\Android\android-sdk>shortNamePath
C:\PROGRA~2\Android\ANDROI~1

Kimbo's answer is perfect for normal files.

for %I in (.) do echo %~sI

For MsDos file names on HardLinks

The hard links created with mklink /H <link> <target> will not have an MsDos short file name.

In case you dir /X and you discover that missing short name you should expect the followings:

d:\personal\photos-tofix\2013-proposed1-bad>dir /X
Volume in drive D has no label.
Volume Serial Number is 7C7E-04BA


Directory of d:\personal\photos-tofix\2013-proposed1-bad


03/02/2015  15:15    <DIR>                       .
03/02/2015  15:15    <DIR>                       ..
22/12/2013  12:10         1,948,654 2013-1~1.JPG 2013-12-22--12-10-42------Bulevardul-Petrochimiștilor.jpg

Normal file

In this case

> for %I in ("2013-12-22--12-10-42------Bulevardul-Petrochimiștilor.jpg") do echo %~sI

I've got what I expected

d:\personal\PH124E~1\2013-P~3\2013-1~1.JPG

Hard link file

In this case

> for %I in ("2013-12-22--12-10-52------Bulevardul-Petrochimiștilor.jpg") do echo %~sI

I've got the normal MsDos path but the normal filename.

d:\personal\PH124E~1\2013-P~3\2013-12-22--12-10-52------Bulevardul-Petrochimiștilor.jpg`

similar to this answer but uses a sub-routine

@echo off
CLS


:: my code goes here
set "my_variable=C:\Program Files (x86)\Microsoft Office"


echo %my_variable%


call :_sub_Short_Path "%my_variable%"
set "my_variable=%_s_Short_Path%"


echo %my_variable%


:: rest of my code goes here
goto EOF


:_sub_Short_Path
set _s_Short_Path=%~s1
EXIT /b


:EOF

A someone more direct answer is to fix the bug.

%SPARK_HOME%\bin\spark-class2.cmd; Line 54
Broken: set RUNNER="%JAVA_HOME%\bin\java"
Windows Style: set "RUNNER=%JAVA_HOME%\bin\java"

Otherwise, the RUNNER ends up with quotes, and the command "%RUNNER%" -Xmx128m ... ends up with double-quotes. The result is that the Program and File are treated as separate parameters.

use this link, it will automatically convert any path you give to any format https://pathconverter-pp.azurewebsites.net

$fso = New-Object -com scripting.filesystemobject
$fso.GetFolder('c:\Program Files (x86)').ShortName()


PROGRA~2

Inspired by Dr. Scripto's answer

if via a batch file use:

set SHORT_DIR=%~dsp0%

you can use the echo command to check:

echo %SHORT_DIR%

Place this script somewhere in the windows path. I called mine getshort.bat and placed it in the System32 folder.

To use this you must pass a single path parameter after calling the scrip in cmd.exe window.

So open cmd.exe and type something like getshort.bat "C:\folder\file name with spaces.ext" You must double-quote paths with spaces otherwise not necessary.

The script will take the path you supplied and store the shortname in a temporary text file with two versions, version 1 has quotes around the short path, and the other version does not.

I use notepad++ to open txt files so if you do not use that program you need to change the line START "" /MAX NOTEPAD++ "%TMP%\Test.txt" and replace notepad++ with your editor's name.

@ECHO OFF
SETLOCAL ENABLEEXTENSIONS ENABLEDELAYEDEXPANSION
COLOR 0A


:----------------------------------------------------------------------------------


REM SET THE CD VARIABLE EQUAL TO THE FIRST PARAMATER YOU PASSED THE SCRIPT
:: ..WHICH WAS A FILE PATH OF YOUR CHOOSING...
CD=%1


:----------------------------------------------------------------------------------


:: DELETE ANY LEFTOVERS FROM PRIOR RUNS
IF EXIST "%TMP%\Test.txt" DEL /F /Q "%TMP%\Test.txt"


:----------------------------------------------------------------------------------


:: USE THE FOR COMMAND TO CALL A SUBROUTINE TO STORE THE SHORT NAMES WITH AND WITHOUT QUOTES
FOR %%1 IN ("%CD%") DO (
SET ARG1="%%~s1"
SET ARG2=%%~s1
CALL :CREATE_TXTFILE ARG1 ARG2
START "" /MAX NOTEPAD++ "%TMP%\Test.txt"
GOTO :EOF
)


:----------------------------------------------------------------------------------


REM USE THIS SUB-ROUTINE TO STORE THE SHORTNAMES INSIDE THE A TXT FILE
:CREATE_TXTFILE
(
ECHO %ARG1%
ECHO %ARG2%
)>"%TMP%\Test.txt"
:: THE NEXT LINE WILL RETURN THE SCRIPT TO THE LINE BELOW THE CALL COMMAND ABOVE AND CONTINUE EXECUUTION AS NORMAL
:: NOTEPAD++ WILL ATTEMPT TO FIND AND OPEN THE NEWLY CREATED TXT FILE WITH THE SHORTNAMES INSIDE
:: CHANGE TO WHATEVER TEXT EDITOR YOU HAVE TO OPEN TXT FILES IF YOU DONT HAVE NOTEPAD++
