Hello,

how is your data transfered to your PC? If your PC depends on visible FS
on your device (e.g. your device acts as USB mass storage device) you
also can emulate a FS with exactly one file on it. Your log data is
written block-by-block and the PC side read the "file" transparently
through "virtual FAT file system".
If you upload your data via serial line or something else a FS is
definitely not needed.
