I have a folder A with files 001.jpg, 002.jpg, etc
I also have a folder B with different files but with the same names; 001.jpg, 002.jpg, etc

I want to put all the files in the same directory - is there something that will automatically rename them or something so that they can all be in the same directory?

Thanks,

Dave

Yes.
In folder one, select all/rt-click/rename
Enter an appropriate name (i.e. my vacation)
All will be renamed "My vacation001, etc.
Irfanview also has a batch rename utility.

Ah great - I never knew about that!
