Problem with Saving File- It Shows Message: " CfileException 0 in C:\folder\file.skp " and does not save file

Tried that - didn’t help…

Let me know if you are using any of the following…
-Dropbox or any other network / cloud storage or backup service
-Antivirus (like AVG)

That might help us narrow down on the issue. What we normally see with a CFileException is something locking the file temporarily, while SketchUp is trying to access the file or backup of the file. It may also be permissions related. I’ve seen situations where a user creates a new user account on their computer, logs in with that new account and suddenly, everything works. It has to do with a corruption in the user profile.


I would add the Preview pane in Windows Explorer to the list.

Hi Nathanz!
I can help with that. First off, this CFileException has something to do with your computer’s ability to allow SketchUp to take control of a .skp or .skb file. Things that usually affect this are:

  • Antivirus (AVG used to be a good example) will sometimes lock a file to scan it, during a save or autosave. Most AV applications have a ‘suspend’ option which can be used to see if the CFileException also ceases in that same time period.
  • Corrupt User Account can sometimes break the user access rights to save in particular folders. This can be tested by creating a new user account in your operating system, then logging into your computer with that new account. Under this account you can see if the CFileException stops.
  • Active files (you are working on) that are kept on remote storage (Network drives, cloud storage, backup sync services like Dropbox). Network speed and model size will often exacerbate this particular issue. Be sure that any active file is being saved on a local partition (like your C:/ drive).

We cannot fix those particular issues, that would be the a job for your local IT specialist, but most of what I’ve suggested can be self-diagnosed and successfully repaired pretty easily.
