Deciphering!?

[brispuss]

Thanks.

But on checking FreeArc commands, there don't appear to be options -a1, -mfbt4, -d????, -fb???, and -mc* available. Therefore this suggests that FreeArc wasn't used in the example in my first post.

Also quickly checked 7-zip commands, and it appears this doesn't have many of the lzma options either! So presumably 7-zip was not used in the example above(?)

So, any other ideas which program was used that used ALL of the example options?
