Blender seems to randomly save as incremental rather than overwriting the existing file

Hello,
I have been running into an issue lately in multiple versions of Blender (5.2, 5.1.2, 5.0, and 4.0 releases) where sometimes when I press ctrl + s to save the file, instead of overwriting the existing file, Blender saves as an incremental file. This means that in my project folder I accumulate lots of Blender files; this doesn’t happen all the time, but it seems to be completely random timing when it does.

I’m not sure if this a configuration I might have, or a mistake I am making, but I thought it was unlikely that it was a bug, since it is happening on lots of different versions of Blender.

I am using an Intel Core i5-14600k, RTX 3070, and a NVME SSD, all of my drivers are up to date, and I am running the latest version of Windows 11.

Weird question, but do you happen to have Pie Menu addon or something like that?

It’s unlikely, but I’ve run into something like this once, until I realized that I was accidentally opening a menu for split second and gesturing in the direction of Incremental Save :sweat_smile:

Saving incremental blendfile2.blendblendfile3.blend

or incremental backup files blendfile.blend2blendfileX.blend3 ??

Setable in Blender → Preferences → Save Versions: some_number ?

I have a few addons, but not Pie Menu.

It is saving incremental, my folder is full of blendfile2.blend, blendfile3.blend and so on.

Hm… alternatively look at your keymap, maybe you’re pressing something by accident.
By default it says: “Ctrl + Alt + S” is for Incremental Save.

Mine also says Ctrl + Alt + S, however recently I have been using the file > save button to see if it was just on the keyboard shortcut, and it still saved incrementally.

:thinking:
Well, that certainly changes the situation. I’m out of ideas :saluting_face:

…maybe keep “Info” space opened and check which operator was used when saving?

At least better than not saving.. :sweat_smile:

That’s a good idea, the weird part is sometimes the pop-up says saved incremental when I pressed the normal save button, but sometimes it brings up the normal saved pop-up yet it has saved as an incremental.

Hello !

Just basic debugging-fu… as I have no idea about what it could be…
First, try on a basic scene and make sure you can reproduce the bug !

Then restore default settings and try again …

Then disable all addons…

Then look at shortcuts / keymaps…

Is it random in sometime it works, sometimes it don’t ?
Then that sounds pretty weird…

Sadly to say that but wish you good hunt…

Yes completely random, some days it doesn’t do it at all and then sometimes it will just do it loads.

Generally if it does save incremental it will do it for the next few saves, and then go back to being normal.

I only ever seem to have the issue with my large scenes, it happened on my previous project as well, but it never occurs on test files or smaller weekend challenge ones.

Outch… those problems are pretty hard to catch… trying to disable some addons might be a first step… I suppose nothing pops out in the terminal when this happen ?

I have a theory. Workspaces let filter add-ons. So you might have some add-ons enabled in some files maybe? I don’t use it myself, so not really sure how that works, but maybe you have something like this:

Can you show us the keymap settings for Crtl+S?
Mine looks like this:

if you press numpad+ in the file save menu, it will increment the file number. any chance there’s an extra plus sneaking in there somehow?

Sure, the only thing mapped directly to Ctrl + S is save Blender file, there are other shortcuts mapped to Shit Ctrl S and Ctrl Alt S.

I don’t think so, I primarily do it by the keyboard shortcut, not the menu, plus it happens in both.

But show us the settings for the operator call (the expanded version of Crtl+S)

Ah OK, I thought you meant the overview:
