Use hierarchical image directories

[tkem]

One level of subdirectories is probably enough, with the base directory containing max. 256 entries.

with the base directory containing max. 256 entries.

Sorry if this is a stupid question but what is this referring to?

[adamcik]

My guess would be an optimization around FS limitations for number of files in a directory, or speed thereof?

[kingosticks]

That was my guess but I can't find where 256 is a limit.

[adamcik]

Probably just 16² due to using the first two characters of the hash?

[tkem]

@adamcik: correct ;-)
The limit was completely arbitrary, just something that I thought would be "manageable" in some way. In my (somewhat dated) experience, 256 entries per directory would be rather nice to navigate, and 256*256=65K tracks would probably be a larger-than-average collection.
