- Waste does just one thing: it tells you just how much total "wasted"
- or slack space there is on a specified drive.
-
- Slack space is the difference between the filesize that DOS's DIR command
- tells you and the actual physical space taken by the file.
-
- "Huh?" you may ask? Or, "why do I care?" might be another one of your
- questions.
-
- First, let's point out that DOS cannot allocate anything smaller than
- a "cluster" to any file. Sometimes this cluster is called an
- "allocation unit."
-
- So how big is a cluster? Well, that depends entirely on how the size
- of your hard disk and how you've partitioned it. Here is a table
- relating the volume size of a disk (or partition) to the cluster size:
-
- VOLUME SIZE SECTORS/CLUSTER CLUSTER SIZE
- ------------------ --------------- ------------
- 16 MB to 127 MB 4 2048
- 128 MB to 255 MB 8 4096
- 256 MB to 511 MB 16 8192
- 512 MB to 1023 MB 32 16384
- 1 GB to 2047 MB 64 32768
-
-
- This leads us into the "why do I care" part. You care because every
- single file on your disk will take a whole number of clusters. That
- little one line batch file you wrote that DOS reports as having a size
- of 62 bytes? Well, it REALLY takes up 8192 bytes (8K) of your 340 MB
- drive. This is over 8100 bytes of completed wasted space. Space that
- can't be used by anything thing else on your drive.
-
- So with a cluster size of 8K, every file on your disk will waste from
- zero to 8191 bytes of space. But with a cluster size of 4K, each file
- will waste no more than HALF of that. And with a cluster size of 2K,
- each file will waste no more than 2047 bytes!
-
- So, with this simple utility, you can intelligently decide how best to
- partition your large hard drive. If you have LOTS of files, and
- especially if they are little, you will waste an enormous amount of
- space. And WASTE will tell you exactly how much. You no longer have to
- guess.
-
- To Run WASTE just type WASTE at the DOS prompt. It will analyze the
- default drive. Or type WASTE D: for example, to have it analyze drive
- D. WASTE will also analyze floppy disks.
-
- Examples:
-
- WASTE analyzes default drive
- WASTE C: analyzes drive C
- WASTE A: analyzes drive A
- WASTE /h help & credit screen

- This utility is free. Enjoy it, and let's reduce our waste out there!
