Hi all,
just wondering, I have this application that does a lot
of file processing and the size requirements of one
of my installations may pass the 2 gig limit soon!

I am using the BCB stock file routines
like FileOpen, FileCreate, FileRead, FileWrite.

I had realize some time back that there are
both 64 and 32 bit routines in the same name
now my questions:

1. Does the FileWrite routine writes pass 2 or 4 GIGs nowhere do I see 
that FileWrite is 64 bit based?

2. Similarly does the FileRead routine work pass the 2 or 4 GIGs point?

. It is clear that FileSeek is both 64 and 32 bit based. So
doe it mean that most of my recoding will be based on
using a 64 bit file pointer for seek operations and thats it!! (?)

I am using BCB6 on XP

BTW: Should I switch to Vista Ultimate (got it as a gift!)


Thanks
