file recovery

[helenabkl]

I accidently permenantly deleted an autocad drwaing. I managed to retreive the file, however now auticad says it's not valid. I tried almost every option on line and as suggested by chat GPT and nothing worked so far... anyone that may be willing to take a look at the file and help with it? Thanks!

Post a copy of it.

How did you retrieve it? From where?
