Hey all,
As lou_dias said, sometimes there can be a limit imposed on files by windows. If your hard disk is formatted as FAT32, you will hit problems as files go over the FAT32 1gb limit. If this is the case, and if possible, convert your drive to NTFS for many GBs of uninterrupted file-on-file action. Use the windows command prompt and 'convert' command, your system will probably have to perform the conversion at restart...
Is it worth mentioning that such a large hard file may be quite slow to access, or did we already come to and burn that bridge in WinUAE? As far as I can recall, 4gb is also the maximum size the AmigaOS can handle.
Hope that helps.
Tom
EDIT: @adolescent; Absolutely right, FAT32 has a 4gb limit, not 1gb. I seemed to have pulled that figure from under my chair - excuse me, presumably I'm confusing it with something else. Should have noticed from the post that XP is involved, which is NTFS most of the way.
Edited to avoid bumping the thread - sorry no solution in my post!
