Try using this batch file I just wrote
http://filetrip.net/f10322-Wood-R4-Save-Ba...enamer-1-0.html It will rename *.sav to *.nds.sav, but won't rename *.nds.sav to *.nds.nds.sav. It will perform this in the directory from which it was run, and all subdirectories beneath.
The command line it performs is:
Code:
for /R %i in (*.sav) do for %p in ("%~Ni") do if NOT %~xp == .nds ren "%i" "%~ni.nds.sav"
Pretty simple really.
That command line prompt seems pretty advanced.
The one I use is:
CODErrename *.sav *.nds.sav
