Blender can't open blend file using Append. Says "Listing Dirs..." but does nothing Maybe I have a bug here or maybe someone has seen this before, which is why I am asking.

I have a .blend file that I purchased, which has groups of trees in it. In the scene with my terrain, when I go to File> Append Shift + F1  and select the tree Blend file, Blender just shows "Listing Dirs..." at the top of the screen and acts like it is doing something, but never does. I would love to be able to solve this problem if I knew what might be preventing Blender from listing the contents of a .blend file. Has anyone seen this before? Anyone know of a solution?

I would love to post the asset but since it is one that I paid for, I have an issue with posting it here for anyone to grab.
Sounds like a bad blend file.

You mentioned having purchased it, so I am assuming you downloaded it from some kind of online store, right? Have your tried downloading it again, file might be incomplete or have become somehow corrupted.

Is the file very big, does it contain a lot of images (like say textures for the trees or something) or very big meshes? It might just take a while to load all information.

Can you open the file directly?
