Here's the updated source code for v5 of set_empeg_max_fid.c (attached).

Just cosmetic changes this time. No need to re-run it if you've already used v4.

-- improved parsing of /proc/partitions
-- fixed display of "sectors" value
-- tidied up display of program name
-- modified license terms to permit embedding within player app in case Peter or others decide to do so. (hint hint..)

Cheers
