The primary caution to be considered is memory. CTools™ can handle fairly big files, but has its limits. If you do a big operation, don’t expect to b able to do another big operation without saving. For example, if yo do Pascal to C on a file, then Source Code Formatter, it will crash. If you do Pascal to C on the same file (after you restart), then save, THEN do Source Fomatter, it will probably not crash (didn’t for me). See?
