I have a database of 250,000 tiny audio files that will grow to perhaps 500,000. I need to copy this to my Android phone's ext4-formatted internal storage.
I have discovered that some computers are unable to support such a large number of files in a single directory.
Will an Android 5.1 phone prevent me from moving 500,000 files to a single directory? If it permits this number of files, will it experience a slowdown in reading the files if they are all placed in one directory as opposed to distributing them numbered directories?
