I have to rename multiple files. original file name: os_work_465.jpg to os_comp_465.rtf os_work_466.jpg to os_comp_466.rtf. and so on. In short I have to replace work by comp and *.jpg or *.pdf extensions to *.rtf. No if i get file such as - abc.jpg or abc.pdf then i have to rename as abc.rtf There are about 50 folders having 10 subfolders each for renaming. Please tell me how I have to do?? Using simple Batch file or any software

It's anybody's guess why you'd change file extensioms. But those are *NOT* DOS filenames. ===================================== If at first you don't succeed, you're about average. M2

Check some of these utilities: http://www.webattack.com/freeware/s...

As DAVE mentioned, some of those are very good. Bulk Rename Utility would be my pick: http://www.bulkrenameutility.co.uk/...

i will tell you how to do it by a batch file..... type the following code in a batch file.... === @echo off ren *.jpg *.rtf ren *.pdf *.rtf === Now Copy this bat file to each folders you want to rename *.jpg *.pdf files to *.rtf........

That only works in his example of abc.jpg or abc.pdf to abc.rtf. You're not paying attention to what he wants to do. The other files would be handled like this: ren os_work_???.jpg os_comp_???.rtf ren os_work_???.pdf os_comp_???.rtf and that assumes the file names all had 3 characters replacing the ??? wildcards. And did you notice he had 50 folders, each with 10 subfolders? That's a total of 500 folders. And you expect him to copy his batch file to each of those? That's why we suggested bulk renaming utilities.
