auto number in folders

[musicmp3]

Hello - I have 7 folders with 101 mp3's

How do I rename the files 01 - 101 in the folders.

That is, FOLDER ONE 01-13, FOLDER TWO 14-25. FOLDER THREE 26-39 etc etc


Presently in each folder they start with 01 in the filename.

Thank you

Go to the top level folder. In Filters (12), tick Files and Subfolders. Click to sort by Name and then by Sub Dir., so that the files are in the correct order.
