The SketchUp model I’ve been working on has the “Unexpected File Format” error… for awhile.
I changed the file from .skp to .skb numerous times and still give me the same error.
Please respond, as this will save me a lot of extra work if this can be fixed…
Note that I have never used any plugin to work on this model.
Changing the name from skp to skb actually worked for awhile, especially when I could not open skb on SU. When the main skp file failed, I could use the other one to access the recently changed, uncorrupted files. Now, the same error occurs regardless.
If I understand, you were manually creating a backup by renaming the skp file to skb?
The problem with that idea is that SketchUp itself creates an skb file each time you open a skp, and if the skp is corrupted this will overwrite your supposed backup. If you want to make a manual backup, make a copy of the skp, don’t just change its extension.
