Export to a custom location

1. Android supports encryption of the internal memory device. SD card is not encrypted.
2. Entering an extra password to export and unpack is inconvenient.
3. Getting the SD card out of my smartphone is inconvenient (taking the cover off, thick card) and long (reboot); it doesn't seem to actually work as USB storage (even if I unmount the SD card); a bug in Android prevents new files from becoming visible on MTP immediately. PTP, however, works, so I can put the file into Pictures/ on the device and add ".jpg" to its name, which is faster. Maybe there is a saner way, but I hope it doesn't benefit from the file being in the card's root. // A saner way is to use PTP while MTP is selected, but I still had to make a script to copy all the apps' backup files without navigating.
4. TTT supports import from a custom location, so why not export?

5. It's easier to rsync a dedicated folder to a computer than to build an rsync filter expression that covers all possible export file names.
