Troubleshooting: Mylio Photos Utilizes More Storage Than Expected on Android SD Card
Updated over a year ago

If you are using an SD card to store your Mylio Photos Library on an Android device, you may see unexpected storage use of the SD card when syncing the Mylio Photos Library. This is due to SD Cards being formatted by the factory in a way that makes them inefficient for storing large quantities of small files.

The chart below displays an estimated usable media count for various card sizes.

*256 GB cards are formatted by the factory in a way that makes them very inefficient to use with smaller files. You can choose to reformat the SD card to get more usable storage space.

WARNING: Reformatting an SD Card will permanently erase all of its contents.
