There's certainly a possibility that the renaming issue is a limitation of Windows file names.
I know from experience that Windows doesn't handle all characters in file names as well as it might.
FWIW, I often avoid characters that are not in the normal alphabet and a few others like .-_ to avoid the risk of untoward interpretation as special characters like $ : ! ( ) and so on. In my case that's because I often use scripts like bash or Python to manipulate files, when some special characters can cause mayhem.
I am sure that is not the problem here.
I took one of the files that just will not rename and put it in a directory all by itself. I then renamed it simply 1.sgu on the hard drive.
Now the embedded name of the song was "Off Minor". That is about as simple as you can get. When I tried to rename it via the long filename utility, BIAB simply renamed it 1.sgu.sgu on the hardrive. It if worked properly, the file should have been renamed Off Minor.sgu
That did not happen.
That in essence is the problem. I have over 300 of these song files in my collection, dating back from the very early days of BIAB, that just simply cannot be renamed by the program. I can only assume that they might have been created by one of the earliest versions of BIAB and is just not comparable with being renamed. They open just fine in the program and they do play properly, ya just can't rename any of them using the built-in utility.
Like I said, anyone can go grab the song files I put on dropbox and play with them yourself to see if you can come up with a solution.
