Hello... So I've perused my Titanium backup folder in the past and I'm familiar with the various files that are produced and kept when making backups of APK files. There is MORE THAN ONE file associated with a given app's apk files in Titanium. So I was looking into the "Send this backup..." option in Titanium to send someone the apk file that I had. That option attached THREE files:...one with the filename/extension ".properties" one with "tar.gz" and one "apk.gz" I was wondering the significance of each of these files?? I'm assuming that the ".properties" file is a settings/data file. I'm familiar with the extensions "tar" and "gz" as archive/compressed files...but I was wondering the difference between tar.gz and apk.gz?? Also if I simply wanted to send the apk file to someone "manually" through my computer or keep the apk file on my computer archived without caring about the data, do I simply download/save the apk.gz file, decompress down to the apk and keep that?? THANKS!
