# This is a combination of 4 commits.
# The first commit's message is: SD Card Alpha Sorting First iteration of alphabetical sorting for SD cards, both slow+efficient and fast+rammy. Option for folders to sort first, last, or not at all. # This is the 2nd commit message: Expand on More RAM concept, address minor bugs # This is the 3rd commit message: Improvements, more SORT_USES_MORE_RAM With this option, always keeps the dir in RAM, doubling as a cache for getfilename. A board with only 8K of SRAM is cutting it very close. # This is the 4th commit message: Completed SORT_USES_MORE_RAM implementation For the MORE_RAM option we need to buffer both the short and long names, even though long names are sometimes redundant. Worst case, all the names are max length. We can save some RAM by not storing these. We could save more RAM by only storing the visible part of the long name.
