I tried various things, but couldn’t recover anything useful from the file. Was there an SKB file next to the SKP? If there was, try renaming that with an .SKP extension, and see if it opens ok.

these are all the files that i found and i tried your suggestion but it didnt work
@colin

Still no success. What file system are you on that creates RAR files?
