1. VIEWING QUAKE FOLDER LOCATION ON WINDOWS PC WITH USB CORD TO PHONE


If you have just installed reboot your phone first.
Connect the USB cable to your PC.
Select "media sync mtp" to browse all files (name varies by phone model).




Note: If you want to move Quake files to your phone like maps or registered
Quake pak1.pak, reboot your phone first. Android uses a protocol called MTP which relies
on MediaStore for new files, and Quake cannot update it, so there are likely folders and files you cannot see.
This will save you many headaches/confusion. It rescans on a reboot. This only applies to USB.

If you have File Manager app, go to Apps->File Manager (name may vary).
Otherwise, you may wish to get one from the Play Store (example - used to be free, now $0.99 per year).
