File System is an unstructured way to store data. File manipulation is a process of manipulating the data stored in file. In our project, we will use the Reader-Writer Scenario to manipulate the data in a file. In our project, if one of the people tries editing the file, no other person should be reading or writing at the same time. However if some person is reading the file, then others may read it at the same time.

• One set of data is shared among a number of processes.

• Once a writer is ready, it performs its write. Only one writer may write at a time.

• If a process is writing, no other process can read it.

• If at least one reader is reading, no other process can write.

• Readers may not write and only read.
