Filename Extension


  • In DOS and some other operating systems, one or several letters at the end of a filename. Filename extensions usually follow a period (dot) and indicate the type of information stored in the file. For example, in the filename LETTER.DOC, the extension is .DOC, which indicates that the file is a word processing file.  1  2  3
