DotNetMatt offers more insight:

The screenshot shows they used a data recovery software (https://www.r-studio.com/Data_Recovery_Technician.shtml) so it is likely that they were able to restore the files, however we can't know for sure. We can see 2 files have a size of 0 bytes so these are probably lost forever. When you delete a file on a computer, it's not really gone. It's still on the hard drive, but it is not visible to the user and the space used on the disk by this file is marked as free so it can be used to write something else when needed. So if nothing was written over the file then it is recoverable.

There are also possibilities to calculate what are the missing parts of a file, it looks like the software has this capability (file repair)."
