Headers and footers of some important file types

The headers and footers of some important file types have been given in the table given next. The footers given in the table are either in the end of the file of specified file type or are in the ending Offsets of the file such that you can use them as footers to recover the data.

You can also search yourself for headers and footers, different from these file types, by using the EDIT command of DOS or by using any disk editing tool. I have used the hexadecimal system to represent the information to make it easy to understand.
