re: Inaccurate record of free drivespace after deletion Tuesday, June 17, 2003 at 2:38 pm Windows 98 Annoyances Discussion Forum Posted by Paul D (2162 messages posted) Clusters are indeed units of disk storage. On a 20gb drive your clusters are (from memory - it will do as an example) 4096 bytes. Files can only occupy complete clusters, so if you have a file of 4097 bytes, it actually occupies two complete clusters, or 8192 bytes. That's 4095 bytes of slack (effectively useless)space. Obviously, many small files will waste mor space than a few large ones. Cluster size increases with partition size. If you had partitioned your drive so that you had 3 logical drives, each less than 8gb, your cluster size would be 2kb instead of 4kb.
