What complications could arise in a time-sharing system if two processes require access to the same file at the same time?
File manager could grant several processes access to the same file if the processes are merely reading data from the file, but conflicts can occur if more than one process tries to alter a file at the same time. Thus, a file manager may allocate file access according to the needs of the processes, allowing several processes to have read access but allowing only one to have write access. Other systems may divide the file into pieces so that different processes can alter different parts of the file concurrently.

This helps prevent conflicts and ensures that only one process can access the shared resource at any given point.
