The way I usually do such things is make a batch file. You will need a command prompt, a text editor (notepad will do) or a hex editor if you prefer.
Assuming windows xp, I can adapt for earlier later or unix if you need.
Open the folder get a command prompt there.
type
dir /b *.sav >>a.txt
If you want post up the text file here (spoiler box or something) and I can make something to do the rest for you.
After hitting return a file called a.txt will appear in the same directory with all the names of the save files in there.
Open the spreadsheet app up.
In Excel 2003 there is an option to "import external data" in the data pulldown menu. Two things now need to be done, I find it easiest now to import a normal version first.
Repeat the process and use the fixed width box instead to slice off the names as you need them.
In open office (I only have 2.2 on this machine) it is available when you try to paste it in from another source (open in notepad and paste across), same theory as above other than that.
You should now have two lists.
use the fill option to add rename in the first column
do the same but with something like # (a character not likely to be in a name) for the second
If the names have spaces add a " next
original names
another " column if necessary
# again
" again
new names
" again
Highlight the lot and paste it into notepad. Each section will be bounded by a tab so highlight it and copy it.
Search and replace it for nothing
Do the same for # but use a space instead
You should start out with something like
Code:
RenameÂÂÂÂ#ÂÂÂÂ"ÂÂÂÂAtest.txtÂÂÂÂ"ÂÂÂÂ#ÂÂÂÂ"ÂÂÂÂt.txtÂÂÂÂ"
RenameÂÂÂÂ#ÂÂÂÂ"ÂÂÂÂxoffset.txtÂÂÂÂ"ÂÂÂÂ#ÂÂÂÂ"ÂÂÂÂFset.txtÂÂÂÂ"
RenameÂÂÂÂ#ÂÂÂÂ"ÂÂÂÂFyset.txtÂÂÂÂ"ÂÂÂÂ#ÂÂÂÂ"ÂÂÂÂyset.txtÂÂÂÂ"
and become
Code:
Rename "Atest.txt" "t.txt"
Rename "xoffset.txt" "Fset.txt"
Rename "Fyset.txt" "yset.txt"
Save the whole thing as a batch file (extension = .bat) and copy it to the save directory.
Double click it and a second or so later all your files will be renamed.
