Blender is by default config to save backup file from previous saves like .blender1, .blender2 and this is a good thing in case you mess up. What i want is to config blender to place this specific files in a subdirectory. Right now they show up in the list of blender files and make the list really long if you have a few scenes. Is it possible to config blender to do this?

Illustration of the structure.

.blender_folder
..Backup
...file1.blender1
...file1.blender2
...file2.blender1
...file2.blender2
..file1.blender
..file2.blender

I took a little time writing an addon for Blender, which will move the backup save files to a sub directory every time you save. You may change it however you want it to work.

I hope it works for you guys. :)

Simply save the code below into a file called something .py, I called mine "blender_move_backup_save_files_to_a_sub_directory.py".

Then import the file by clicking: File > User Preferences > Addons > Install From File... > Finally select the file and activate the addon.

First of all, thank you Jonathan for writing this script. I'm much happier with this arrangement of backup files!

It didn't work out of the box on my Mac because the some of the OS paths were constructed with hard-coded Windows backslashes, so I went in and changed them to be platform independent.

I hope this is helpful to someone. Since I hadn't seen any later versions of this script, I went ahead and advanced the version #.

In Blender the file selector window have a filter for excluding BLEND1/BLEND2/... files. It's located inbetween the show BLEND files and show image files (a grey icon with the Blender logo). enter image description here

Don't forget to activate the filter altogether by clicking on the funnel icon to the left of all the possible filters.

In Windows 7 you can right click and select group by type, and then click on the arrows next to "BLEND1 file", "BLEND2 file" et.c. in order to collapse these. This helps to remove clutter when browsing the files in Windows Explorer. Windows remembers your selection.

And consider using software for version control like GIT (http://git-scm.com/). Then you do not need the BLEND1/BLEND2/... files at all! And have greater flexibility experimenting.
