FSRW has the following limitations. Some of these will be addressed in future releases.

• Files larger than 2GB are not supported.
• On FAT32, only the first cluster of the root directory is supported (but for 32K clusters, this is up to 1000 files.)
• Subdirectories are not supported.
• Long file names are not supported.
• Seeking is not supported.
• Only one file at a time may be open.
• We ignore the write-protect tab on cards (we have no signal line for this presently).
• For cluster sizes below 32K, write speed can be significantly slower because the Propeller does not have enough memory to buffer much of the FAT.
• If a card is somewhat full, writing the initial block of a new file could take a while as the FAT is scanned. We can improve this somewhat.
• No explicit date or time support yet.
