I want to be able to test it myself.

why were you torturing yourself with the android version in the first place

v3.1.0 Preview 4 is where the file transfer process became available, which we have a Linux build available.  I would recommend running Preview 4 on your Linux device first, then copying the transferred files from Linux ($HOME/.config/unity3d/VyletBunni/DELTATRAVELER) to the Windows directory (%userprofile$\AppData\LocalLow\VyletBunni\DELTATRAVELER).  As ever, you can download the preview versions on the DELTATRAVELER website.

We have plans for this, but I have to spend $900 on a Mac first.

It should automatically transfer the file(s) to the new location.
