I accidentally deleted a complete project folder, 2 days before releasing the song we have being working for 2 months. I managed to restore the whole project using data recovering software, and it actually did an amazing job, it restored everything (7GB), but all of the project files, back ups, autosaves, wont work, (about 20 project files, and 40 autosaves). It says.. the file is broken.. I tried all I can think of, please help, if someone has an idea on how can I open the project files. They wont open as zip files nether. It seems so strange, the data recovery restored all audio files, they play with no apparent problems, and not even ONE project file. how can that be possible? is there any other known way to open a corrupted project file?
