Hi,
Had 17mb blender file…
No new object, working for about an hour… Small things…nothing great… Now saving 850mb…
I began to delete objects and collections one after another and save everytime to see maybe where the candidate hides…Monday I will go on. If I find the problem I post an update. Maybe I post a blender file with the problematic object.
Any idea, any tip ? … In 3dsmax there is something called “garbage collector”…
Anything like this in blender?
Thanks for help!

I am a bit in a hurry, so cant help in detail, but as a simple rule of thumb, turn on file compression in the prefs under “save & load”
Outliner → Orphan data… maybe you should delete some things…
hi ,
so i checked it down. compress did not do anything…860mb
orphan showed this at this moment…so, much of materials and images…after purging it went down to 360mb
after deleting ALL objects in outliner i still got this in orphan…
after deleting all this orphan i had 1mb…
so can anyone explain me how this could come…as it seems i have node groups, images,materials,and the one time meshes. how can i see what the big player was? i feel that it was the meshes…but how do i get orphaned meshes if all meshes are deleted ?
it would be super if someone could explain what is / was going on here. do i get images of materials saved in the file?
big thanks!

It looks like you were importing assets with a lot of textures, I’d bet it was the textures. but high res geometry can take up a lot of space too.
i think textures are only a reference ? can i define that, if they are included in the file? it seems that the materials shot that up…so it has to be the textures…why are they saved in the file?
Usually, using an image file does not attach the file, but only the path goes in, so it has nothing to do with increasing the capacity of the saved file.
However, if automatically pack resources is enabled, the image is stored inside the project and the capacity is increased.
If you save a simple scene like an image.
The typical storage method is 1 Mb.
However, if you save it after automatically pack resources is enabled, it will be 120 Mb.
and to unpack all i check “unpack resources” or “unpack linked libraries” , or both? and then…
It’s a function that I don’t use. 
Please refer to the manual.
https://docs.blender.org/manual/en/latest/files/blend/packed_data.html
so i checked “unpack resources” then “remove pack” and all is good now. 
…so maybe i ticked a wrong hotkey or a combination that enabled this packing…?
The shortcut does not appear to be specified. I don’t know why 
If you didn’t set the default setting to the after automatically pack resources, it won’t happen.
…in the problematic file this is UNCHECKED ! 
…maybe this came in “objectrelated” with appended objects ??
