Batch renaming some files

Hello,

I have some 365 files (tif format) named 1.tif, 2.tif... and I want to rename them to an actual date in 2010. as the name now reflects the julian date and I want to transform it to normal date. for example 1.tif file should be: image_01-01-2010 etc..

I tried many methods but it didn't work.

Thank you

What exactly do you have and what do we need to invent for you?

1. Do you already have the function that turns a number in the range 1-365 into a data string yet? If so, please post that part.
2. Do you already have the part that gets a file list and loops over all existing files and constructs source and desitnation filenames and calls movefile? (This part is trivial.)
