While saving, it was not possible to create the backup file.
Causes
The program is trying to save the existing file by creating a backup copy (for more info see the Save page).
The operating system prevents, however, to carry out the operation.
- You cannot rename the existing file "filename.ac2" because this file is protected.
- You cannot erase the "filename.ac2.bak" file.
Possible causes include:
- You are working on a directory without writing permissions
- The existing file has been opened by someone else on another computer, in another session or it is locked by another process.
- The "filename.ac2.bak" is write-protected.
Solutions
- Save the file with another name to avoid losing the changes made.
- Find out the possible cause.
- Manually delete the file "filename.ac2.bak"
