Question: I am trying to upgrade an old project, but the Project Editor keeps telling me "Not Enough Disk Space For Temporary File". But I have more than enough room. What is the problem? 

This problem appears when you have a large partition with more than 2 Giga-Bytes of space free and is caused by a bug in one of the Windows kernel's standard functions. This is a problem in Windows 95 and Windows NT 3.51. This function returns an incorrect value when there is a large amount of free space and causes the Project Editor to think there isn't enough room.

As of Windows 95 OSR2 and Windows NT v4.0, this function has been replaced by another, and the problem will not occur. If the problem appears, a suggested work-around is to temporarily reduce the available space on the hard disk to less than 2 Giga-Bytes. This may be achieved by:

a) Copying a sufficient number of files into a temporary directory.

b) Increasing the size of the windows swap file on that partition to occupy the required space. This may be done using the Virtual Memory settings of the computer's system properties.

Once the upgrade has completed the storage space may be freed.
