In computing, share is a command for MS-DOS that allows software to perform file locks. Locking files became necessary when MS-DOS began allowing files to be accessed simultaneously by multiple programs, either through multitasking or networking.[1][2][3]

The command is also available in FreeDOS[4] and PTS-DOS.[5] The FreeDOS version was developed by Ron Cemer.[6]

Design

There were five locking modes:

  • Deny None
  • Deny Read
  • Deny Write
  • Deny All
  • Compatibility (designed for backward compatibility with existing MS-DOS programs)

The program runs as a Terminate and Stay Resident program and is typically loaded at boot-up.

Syntax

  • /F:space Allocates file space (in bytes) for file-sharing information.
  • /L:locks Sets the number of files that can be locked at one time.
