A FAT32 directory can have 65,536 directory entries. Each file and
subdirectory takes from two to thirteen entries, depending on the
length of its name, so those entries can disappear long before you
think you've used them all up. Your total of 22,657 files could very
easily use 65,000 entries.
So, by having all of these empty dubdirectories, you will be limiting what you can put on your reader as these subdirectories will take two or more directory entries and they'll just sit there unused.
