Juergen, 

Könnten Sie bitte mir helfen... can you point me to the source of this information, since some networks have legacy devices, and different classes of flash file systems.

Dankt meinem freund,

no, the compact flash cards have "dos" filesystems,
squeeze is not needed and not offered by the ios
on those filesystems. Esp. after format squeeze on the compactflash
is not needed. 

The old , linear fast PCMCIA FLASH Cards (but not compatible with 
the Newton :-( as a former form of ip* was named) )
did also not need squeeze but you had to delete a file 8? 9 ? times
to free the blocks, or use squeeze if offerde by yoru IOS.
