___jb_bak___ and ___jb_old___ files in PyCharm

Question

When I got some PyCharm project from my colleague I saw some backup files of *.py files.

This files have types: *.___jb_old___ and *.___jb_bak___.

I open the files in Notepad++ and see that these are identical backup files of the corresponding *.py files. I asked my colleague, but he didn't know what these are.

1. Why are there TWO identical backup files for each *.py file?
2. How can I tune PyCharm? We want to turn off this backup.

Google gave me nothing :(

You can disable "safe write"

Use "safe write" (save changes to a temporary file first) If this check box is selected, a changed file will be first saved to a temporary file; if the save operation is completed successfully, the original file is deleted, and the temporary file is renamed.
