ASC (file format)
SUMMARY: Defines the ASC file format that normally represents text files.
Files with an extension of ".ASC" are usually ASCII text files, similar to the TXT file format. For Windows, while double-clicking an "ASC" file does not normally open Notepad, these files can normally be viewed with such a tool.
Windows users: NOTE that unless you have configured your computer with the file extension viewing tweak, it is possible that a filename that looks like it ends with ".asc", especially one attached to an e-mail message, actually has a hidden OTHER extension, meaning that if you double-click the file, it may actually run a computer virus!
