I have to admit that I was wrong.  The RISC OS 3 v. 3.6 limit is 4GB.

And, in the new FileCore they have increased this to 256GB.

My source of information is a couple of information sheets
that were sent to the Clan in September 1995.

I quote from the RISC OS 3.60 sheet:
"... FileCore and ADFS have been extended to support hard discs
of up to 4GB ... "

I quote from "The New FileCore":
"... the new version has been extensively rewritten and has been
designed to support discs of 128GB. ..."

In other words, there are three different FileCore's out there:
1) The one in RISC OS 3 up to and including v. 3.5 which only
supports up to 512MB.
2) The one in RISC OS 3 v. 3.6 which supports up to 4GB.
3) The new one that is soon to be released and that was
beta-tested by Clan members.

Of course there may have been changes to 2) and/or 3) since
September 1995, but this is the information I was refering to.
I have not received information from Acorn that denies this
information through the Clan, and I assume that would have
been the case if it had been changed.


I am sorry about the confusion I have caused, and I hope
that this settles the issue.
