MobileSheetsPro makes a copy of every file you import and places it into the folder listed under Settings->Storage->Set MobileSheets Storage Location. If you don't like that behavior and would prefer to control your own files, just uncheck Settings->Storage->Let MobileSheets Manage my Files. Then any file you import after that point will be used from its original location. If you let MobileSheets manage your files, then you really shouldn't be worrying too much about how the files are named or where they are located. If you want to replace a file, long press the song on the library screen, tap the three dots at the top right and select "Swap File". I do plan on adding support for renaming files, I just haven't got around to adding that yet.
