These CAID files should be the only ones you need with these keys.

MAIN is a standard file that will register the all the currently used (key.bin) CAIDs with your decoder at 
switch on. As Bulsatcom/Polaris is now open this includes CAID 0604 needed by some echostars.

CDNL contains only CAID 0622 for Canal Digitaal NL for anyone experiencing freezing problems.

BULSAT contains only CAID 0604 for Bulsatcom for anyone experiencing freezing problems.

IRDETO contains both 0622 & 0604.

D1 & D2 are for use with Diablo v1 & v2 cams when used in connection with Dragon/T-Rex CAM and latest Predator file,
only have CAIDs active for extra channels opened by Diablo. (v1 has 0D00, 2600 for alternative
Biss channel selection & for me TRAVEL on 4.8E which does not open on my Topfield with Dragon/T-Rex) (v2 has the same as v1
plus also 0500 for exclusive Viaacess hacks on Diablo v2 and 0604 but no 0622 in either for CD NL I2 as I use a Gamma Card).

Numerous other CAID files have been added over time, these are only for official cards or when channels are open with Control
Words (eg DSMART, SKYIT, ZEE, SKYUK, TRING etc)

Note:  Fixed CW can be left on as dead Control Words have been removed from the key.bin.
