- SIZE (and ATSIZE) Art Merrill
- Command(s) PC Magazine Vol 5, No 1
- Copyright 1986 Ziff-Davis Publishing Company
- ______________________________________________________
-
- 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.
-
- Notes:
-
- 1. Requires DOS 2.0 or later.
