I am using a CLI program called metaflac (http://flac.sourceforge.net/documentation_tools_metaflac.html) to remove padding from various FLAC music files on my computer. Using the following command in a batch file (with metaflac.exe in the same folder) successfully completes this task for an individual file:
metaflac --dont-use-padding --remove --block-type=PADDING "filename.flac"
I have to do this for several thousand files and don't want to do it all manually/individually. Is there an easy way for me to simply direct this command to a directory and have it act upon every file in there? This would save me a lot of time.
Thanks!

Sure. You can do it with a one-liner from a cmd prompt.
for /f "delims=" %I in ('dir /s /b *.flac') do metaflac --dont-use-padding --remove --block-type=PADDING "%I"
If you're putting this into a .bat script, change %I to %%I in both places.
for /f "delims=" %%i in ('dir /s /b /a-d "C:\start\directory\*.flac"') do (
metaflac --dont-use-padding --remove --block-type=PADDING "%%~fi"
)
should do this for you, scanning the entire directory tree from "C:\start\directory" for all .flac files and executing metaflac against each with your parameters.
Suggest you try a small copied subtree first, for safety's sake.
