I discovered a method of freeing storage space on my Samsung SGH-T399 Android phone. Podcasts had stopped streaming, probably because the phone had run out of free storage space for caching. How could I create free storage space? I learned that the hidden /mnt/sdcard/.face folder had grown to 2.65 gigabytes and contained 67,000 files(!). I gambled that the facial recognition files contained there were nonessential.
I deleted the /mnt/sdcard/.face folder, then created a new empty /mnt/sdcard/.face folder. Suddenly the phone had 2.65 GB of free storage. Yesssss!
I used a terrific Android app, ES File Explorer, to discover this bloated folder, delete it, and create a new empty one. Its SD Card Analyst tool displays folders sorted in descending order by size. The .face folder was at the top of the list.
Note that the folder named sdcard isn’t actually the physical sdcard. For some reason, Samsung’s Android file system calls this phone’s internal storage folder /mnt/sdcard. The physical sdcard is named /mnt/extSdCard.
