Here a number of programs that may share a file simultaneously. While this is the case, it is necessary to prevent mutual interference among them. There are three types of concurrent sharing:
1. Immutable files: If a file is shared in immutable mode, none of the sharing programs can alter it. This mode has the benefit that sharing programs are independent of one another.
2. Single image immutable files: Here the modifications made by one program are instantaneously visible to other programs. The UNIX file system employs this file-sharing mode.
