wine users - Dec 2005 - quicken 98 deluxe (year 2000 solution) problem with backup space

I use quicken 98 deluxe (year 2000 solution) with wine 0.9 on a 
slackware 10.2 sysytem.

All has been perfect until now.

When I try to backup I get the following message:

Your backup disk is out of space.
Insert a different disk and press OK.

The problem is this I backup to drive c: (/home/samac/.wine/fake_windows/)

My home directory partition is only showing 8% usage.

So I should not be showing an out of space message, is there a 
configuration option for increasing disk space, or is it directly linked 
to the free space on the partition.

Regards

Steven
