Processes And Files

• A Process, as we saw before, can open a File.
• The Process may open the File for reading, writing or both.
• When a Process is done working with a File, it usually closes the File.
• When a Process terminates, the operating system makes sure all Files it held open, are closed.
• When a File is held open by a Process, and we delete the File, the File is only removed from the Directory, but is NOT yet deleted from the disk. Only when the Process closes the File, will the File be actually deleted from disk.
