share is a command for MS-DOS that allowed 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.
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.
share [/F:space] [/L:locks] /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.
