[quote="nudel"]When you try the rename script are there any error messages shown in the Output Window, Script tab?
If the MP3 files have tags then you could use/adapt the Sort Music by Tags preset from this post to put the titles into the filenames.[/quote]
The Output Window, Script tab shows :
Successfully initialized 'vbscript' engine
Script started successfully
From file rename script by Henrik Ripa
Script completed
Thanks for the link, but something is definatelly wrong with the Rename via script code.
