[windows] How to do something to each file in a directory with a batch script

How do you iterate over each file in a directory with a .bat or .cmd file?

For simplicity please provide an answer that just echoes the filename or file path.

Use

for /r path %%var in (*.*) do some_command %%var

with:

• path being the starting path.
• %%var being some identifier.
• *.* being a filemask OR the contents of a variable.
• some_command being the command to execute with the path and var concatenated as parameters.

I had some malware that marked all files in a directory as hidden/system/readonly. If anyone else finds themselves in this situation, cd into the directory and run for /f "delims=|" %f in ('forfiles') do attrib -s -h -r %f.

• *.* being a filemask OR the contents of a variable.
• some_command being the command to execute with the path and var concatenated as parameters.

Alternatively, use:

forfiles /s /m *.png /c "cmd /c echo @path"

The forfiles command is available in Windows Vista and up.

Another way:

for %f in (*.mp4) do call ffmpeg -i "%~f" -vcodec copy -acodec copy "%~nf.avi"

Alternatively, use:

forfiles /s /m *.png /c "cmd /c echo @path"

The forfiles command is available in Windows Vista and up.

Easiest method:

From Command Line, use:

for %f in (*.*) do echo %f

From a Batch File (double up the % percent signs):

for %%f in (*.*) do echo %%f

From a Batch File with folder specified as 1st parameter:

for %%f in (%1\*.*) do echo %%f

Another way:

for %f in (*.mp4) do call ffmpeg -i "%~f" -vcodec copy -acodec copy "%~nf.avi"
