Case Study: Editing Files with Multiple Data Formats

One problem you commonly encounter when attempting to edit files is multiple data formats. Some files contain a mixture of binary and ASCII data. Almost all modern applications store data and documents in proprietary file formats that contain binary elements. Many of these proprietary formats use a binary header. A header is a block of information at the beginning of a file that is used by a program as a map to the contents of the file.

Editing this type of file with a tool other than the program that created it can be dangerous. You can change the file so that the parent program no longer recognizes the file as being in the proper format.
