How can I change the files of an appimage? How can I change the files of an appimage? I just want to replace the version of a program with another new one, the app that I need is the blender 2.79b version, and I only could find the blender 2.78c version appimage, in the appimages download site in bintray. They have the same file and folder structure so they can be replaced the files without any issue, but there is no such option to "decompress" an appimage file in fatdog64 800 which I currently use in live mode.

To be perfectly honest, there's no need to put yourself through all this aggravation. The tarball as downloaded from the Blender website unpacks to a self-contained directory. All you need to do is to click on the 'blender' binary, and it should fire-up.
