- SIZE Art Merrill
-
- Purpose: Calculates the storage requirements of a file or group of files, based
- on the number of DOS clusters necessary to make floppy disk and hard
- disk copies.
-
- Format: SIZE [d:] (all files, default directory)
- or
- SIZE [d:][path]filename[.ext]
-
- Remarks: DOS stores files in fixed-length allocation units called "clusters."
- For floppy disks, the cluster size is 1024 bytes (two 512-byte
- sectors); for the PC and XT 10-Mb hard disk the cluster size is 4084
- bytes. On such a hard disk, whether a file is one byte or 4Kb in
- actual length (as reported by DIR), it requires the same amount (one
- cluster) of storage space. The PC AT's 20-Mb hard disk is less
- wasteful in handling small files; its minimum set-aside (cluster
- size) is 2048 bytes. AT users should use ATSIZE.COM.
-
- Entered without parameters, SIZE (or ATSIZE) returns the number of
- bytes used by all files in the current directory, the amount of space
- required to copy them to a standard (360K) floppy disk, and the
- amount of space required for hard disk storage.
-
- Entering B:SIZE returns the same information for a disk in drive B:.
- Pathnames and wildcards are supported, so you could enter
-
- SIZE \PROG\*.COM
-
- to learn the number of .COM files, their total size and storage
- requirements, contained in your \PROG subdirectory.
