Several .docx and .xlsx documents were saved on a flash drive, edited in word and excel applications, and changes saved directly to that flash drive again.
These files, when opened, now contain only gibberish of the "}eZ1Ѕqдњ]2^ХЭ*sЖЎfЮcнv1Т2TN" type. Using different encodings to view the file produces only different sets of gibberish. The files have correct names, extensions, and seemingly correct sizes on the flash drive.
An attempt was made to recover the files on the PC where files were edited using word version control (it came up with no files) and recuva (it failed citing "the system cannot find the path specified").
Is it possible to somehow recover the contents of the files?
