Hello SketchUp friends! Guz here to monitor the CFileException0 issue. We are narrowing the issue down to applications locking the .skp file during a manual or autosave attempt. This is usually related to overzealous antivirus applications (like AVG) closely monitoring all read/write actions. The short lock time to analyze the file is usually enough to cause the error. Other applications involved in file security during transfer, like cloud backups apps, local network synch applications along the transfer path can also have a negative impact ESPECIALLY if the files are exceptionally large or if the network speed is lagged / slow.
Now we’re trying to discover which applications are grabbing hold of the file while it’s being saved. That should be possible with a Microsoft tool called Process Explorer (Process Explorer - Windows Sysinternals | Microsoft Learn)
If you are experiencing a CFileException error and are comfortable with experimenting with Process Explorer, would you mind launching it the next time you are getting that error? If you want to participate in this research but are not comfortable with using Process Explorer, let me know and we can try to schedule a remote access session where we can take a look at it for you.
Cheers!
