I realize you’ve found another answer – but the fact is that your original code was nearly correct but for a syntax error. Your code contained the line set /A COUNTER=%COUNTER%+1 and the syntax that would work is simply… set /A COUNTER=COUNTER+1 See http://ss64.com/nt/set.html for all the details on the SET command.

For command-line for /F %i in (“c:\foo\bar.txt”) do @echo %~ni For .bat Files for /F %%i in (“c:\foo\bar.txt”) do @echo %%~ni output: bar If the path contains a space, add in “delims=” like so: for /F “delims=” %i in (“c:\foo\bar baz.txt”) do @echo %~ni output: bar baz (Further Reading: http://www.computerhope.com/forhlp.htm )
The problem with your code snippet is the way variables are expanded. Variable expansion is usually done when a statement is first read. In your case the whole FOR loop and its block is read and all variables, except the loop variables are expanded to their current value. This means %c% in your echo %%i, … Read more
xcopy “C:\SomeFolderName” “D:\SomeFolderName” /h /i /c /k /e /r /y Use the above command. It will definitely work. In this command data will be copied from c:\ to D:, even folders and system files as well. Here’s what the flags do: /h copies hidden and system files also /i if destination does not exist and … Read more
How about using sort? dir /b /s | sort Here’s an example I tested with: dir /s /b /o:gn d:\root0 d:\root0\root1 d:\root0\root1\folderA d:\root0\root1\folderB d:\root0\root1\file00.txt d:\root0\root1\file01.txt d:\root0\root1\folderA\fileA00.txt d:\root0\root1\folderA\fileA01.txt d:\root0\root1\folderB\fileB00.txt d:\root0\root1\folderB\fileB01.txt dir /s /b | sort d:\root0 d:\root0\root1 d:\root0\root1\file00.txt d:\root0\root1\file01.txt d:\root0\root1\folderA d:\root0\root1\folderA\fileA00.txt d:\root0\root1\folderA\fileA01.txt d:\root0\root1\folderB d:\root0\root1\folderB\fileB00.txt d:\root0\root1\folderB\fileB01.txt To just get directories, use the /A:D parameter: dir /a:d /s … Read more
As others have mentioned, the rd command has the /s switch to recursively remove sub-directories. You can combine it with the /q switch to forcibly delete a sub-directory (and its contents) without prompting as so rd /s /q c:\foobar What everybody is missing is that rd is not an exact replacement for deltree as seemingly … Read more
I don’t know of anyway to step through the execution of a .bat file but you can use echo and pause to help with debugging. ECHO Will echo a message in the batch file. Such as ECHO Hello World will print Hello World on the screen when executed. However, without @ECHO OFF at the beginning … Read more
You can use a goto to skip over code. goto comment …skip this… :comment
