This seems to happen at the end of back-ups sometimes. No disks are full. If I repeat the backup, the problem goes away. I have Windows 98 SE. A suggestion would be to print the name of the directory that it was unable to create. What directory is created at the end of a back-up? The catalog directory exists, and is on "D:\Program Files\Datahjaelp\Zip Backup to CD\Catalogs"
which is on the hard drive, and had a catalog in it before the back-up started. The log directory is "D:\Program Files\Datahjaelp\Zip Backup to CD\Log" which had logs before the back-up began. The zip file also existed after this error occurred. This problem has occurred twice in about 7 trials so far.
This is a copy of the log file. Note that the successful backup is first. The media is DVD-RAM, formatted to FAT32, which behaves like a 4.7GB hard drive.
