Hello Wilfred,

Indeed..

 WV> For unpacking you need some kind of detection mechanism.

That could be circumveneted by allowing the user to not only specify a compression method for outgoing mail but to als allow the user to specify a decompression method per node. To be used if autodetection fails.

Or let the user specify the "fingerprint" for a custom compression method. From what I remember it is enough to look at the first two bytes of a compressed file. Fingerprint for ZIP is "PK"

OTOH... It may not be worth the effort this late in the game...

GUS... I never used it myself, never had a need for it. It is still under development or is it abandonware like so many other FTN stuff?


Cheers, Michiel
