Files files files.. SD card questions.

[jim lee]

I'm beginning work on something kinda' like a micro database library. Hence, I have to get up to speed with what is available to me working with SD cards. Up 'till now I've happily used the stuff supplied with the Arduino to get by.

So, in my quest I've run across SDFileSystem. It seems like it would do what I want. I'd love long filenames and the ability to rename a file. My question is : has anyone used this stuff? It would be nice to have an honest "I used it it works great" or "Don't bother its just marketing hype." From someone before putting a lot of time in it.

Or even, "Never heard of it. Why aren't you using XXX? like everyone else?"

Because if there is something more popular, that's the direction I'd like to go in.

Many thanks in advance!

For teensies,
there are the following libraries in use
SdFS by Bill Greiman https://github.com/greiman/SdFs
uSDFS by Elm CHaN https://github.com/WMXZ-EU/uSDFS
both support exFAT and SDIO access on T3.5 T3.6

For T3.2and TLC, Bill Greiman's library also supports SPI access to SD card (SPI access with ELM CHaN's library is untested)

there is stock SD Teensy library which supports SPI and also SDIO but only up to FAT32 and 8.3 filenames (AFAIK)
