I am about to wipe the stock ROM from my LG G3 and put in Resurrection Remix to get 5.1.1. My current stock ROM runs 4.4.2 of Android. In prep I downloaded the GApps and ROM zip files to "/storage/external_SD". I see them in there just fine.
I also told my Titanium Backup program to backup everything in the system for good measure. It seems to only backup to "/storage/emulated/legacy/TitaniumBackup". That is fine except I want to be completely sure this is going to the external SD card before I go wiping anything.
From what I have read it seems like "/storage/emulated/legacy" may be going to the external SD card. However that is a bit unclear.
Are there simply two partitions on the external SD card? Are both of those paths on the SD card? Is there an easy way to tell?
