Read the header to check the file type
What are File Headers? (Signatures)
A file header is a "signature" placed at the beginning of a file, so the operating system and other software know what to do with the following contents. Part of the header information is a sequence of bytes or numbers that specifies the file’s type. The common fear is if a custodian changes a files extension or the file wasn’t named using an applications default naming convention. A cybercriminal may, for instance, leave out .exe when he saves an incriminating Windows Media Audio/Video file.
