Unexpected file format :(

[marcell86]

Hi Guys,
I will be very thanful if you could help me with my file.
I just recovered my deleted project file but sketchup warning message keep telling me
“Unepected file format.”
I tried renaming file name and file format .skp->skb.->skp.
Nothing helps

Version of sketchup is fine.
The model in corrupted file must be existing because i can see it in file thumbnail.

Your .SKP file is 'broken'.
The previously saved .SKB file is the previous version, just prior to your last save.
Renaming that file as .SKP should let it open in SketchUp...

If you haven't set your preferences to make backup files [SKB] all is lost !

Note that on a MAC the PC's SKB backup file format is replaced by a ~.SKP file...
