There may be up to 2^18 objects (files, directories or whatever).  Limited by 
the objectId bitfield in the Tags structure.

No limit.

2^20 x512-byte pages = 512MB. The biggest file I've ever seen was approx 
480MB on a 500MB partition. Limited by the chunkId bitfield in the Tags 
structure.

No limit for Linux (except those imposed by Linux). 
For WinCE and YAFFS direct (the RTOS version) the open files are tracked in a 
table. The default size is 100, but this is just a compile-time constant that 
can be modified.

Hope that helps.
