Batch truncating file names

[AZhappyjack]

I am trying to rename a folder full of files (over 300 files) with names in the format:

YYYYMMDD-something-descriptive-goes-here.mp3

to

YYYYMMDD.mp3

All of the batch utilities that I've seen can add text or replace text, but so far I have not found one that will truncate text to a specific length. The ones that do remove text will only remove a set number of characters from either end of the file (beginning or end). In my case, these file names are variable in length, so they don't work.

Any ideas?

Better Rename will do this easily. Truncate file name only to x number of characters. As long as your date strings are a consistent set number of characters, easy. Just pick the 'Truncate' function.
