Compressed .blend files

Hi

Somewhere I read about compressed .blend files (with GZIP).
Is this option somewhere or is this something of old blender versions?

In the save-as dialog:

Good luck.

Does anybody use the compression?
What is the biggest blend file you ever made in MB or GB? Just curious

Isn’t compression on by default?

Using the compression is a great idea- it can shrink files by 30% or so in my experience, and with files that are a GB (it happens), that’s 300 MB of savings. It also makes it significantly easier to share your files and upload them to websites such as this

It isn’t, but it’s probably smart to enable it in the startup file.

@anon30479565 It works pretty seamlessly, I don’t notice any difference when saving or opening compressed files.

The biggest my blend files get is usually a 200-300 mb. Once they hit that point, I usually turn on compression, which does significantly reduce file size.

Ideally, I don’t like working with such big files, and I would prefer to link in other assets as needed to reduce my working file size. While compression doesn’t have much of an effect on saving speed, file size definitely does. if there are a lot of packed textures in your .blend file, that can increase the size pretty drastically. unpacking those to local copies helps to reduce the time spent saving (particularly when syncing files to the cloud)

Two things:

  1. Blend compression is not enabled by default.
  2. You don’t need to enable the compression per-blend. Instead, you can enable it globally in your User Preferences.
