Transactional FTA File System

Thanks for all.

I know that this libraries are expensive. CMX has also this implementation. That is why I'm finding an open source implementation. But I canÂ't find a transactional implementation of FAT.

But why do you want a transactional implementation of FAT? The transactional fats we have seen are not compatible with the FAT12, FAT16, FAT32 that our current PC are using. exFAT may use a file allocation table, but is a completely new file system.

I'm not so sure you can make a FAT16 or FAT32 transaction safe and still have it be compatible with a PC.

So in the end, you should probably look at _any_ transactional file system, and then figure out a way how to transfer files between your device and the PC.

I'm a newbie in this kind of things. But, how do you "build" a FAT File System that can operate with power fails?
That is to say, If you're writing a file in a Flash Memory or in a SD Card, the system must assure that if a power fail occurs in the middle of the writing proccess, data wonÂ't be corrupted.
