I am very sorry to blame UnrealEngine for the things I have encountered. The facts have proved that I may have suffered a mysterious mass file damage, so far the cause is unknown. Because the hard disk test results are normal, other data on the hard disk can be visit normally, except that my project file massively destroyed … I am now seeking help from Seagate, I really hope that this is only UnrealEngine’s problem now:(.
**Thank you very much for the help of all the technology big guys in this post.
Especially , he spent four hours to help me recover the file, thank you very much very much. **
But unfortunately, now I can only check the files one by one, see how many can be saved…
