How can I send someone a .blend file with cache folder included? I've been trying to send a person my .blend file with an external cache folder (.bphys format) to render a fire for me, and when he opens it, he can't connect the two. Any solutions?
Set blender to use relative paths.

Copy the folder with the cache on the same folder as the blend file.

Pack all the images used as textures.

Zip the folder with all those files into a single compressed file.

Send the zip file.
