Windows Batch Script to only keep the N latest FOLDERS in a directory

Question

I have a directory into which I backup MySQL dbs in a folder with the current date.

Now after 30 or 60 days I like to only keep the n latest folders in that backup d

Answer 1

These two different lines work. Keeping all files there might be in the backupDir while deleting only the selected N latest nameDir folders.

This is adjusted from @JosefZ's comment Windows Batch Script to only keep the N latest FOLDERS in a directory

for /f "skip=2 delims=" %%a in ('dir "%backupDir%\" /B /O:-N /A:D') do echo rd rd /s /q "%backupDir%\%%a"

This also works taken from @Magoo's answer from here https://stackoverflow.com/a/17521693/1010918

for /f "skip=2 delims=" %%a in (' dir "%backupDir%\" /b /ad-h /o-d') do rd /s /q "%backupDir%\%%a"
