This section discusses how to recognize
the most widely used types of files in a directory/folder. Some
examples are word processing files, spreadsheet files, database files,
presentation files, rich text (RTF) files, and image files. The main
parameter used is the file extension, mentioned earlier in this
chapter.
The following file extensions describe the file format or the
type of application that was used to create the file (* indicates
the given file name such as client_accounts_12-05-01):
- *.doc – Microsoft Word or WordPad
- *.xls – Microsoft Excel
- *.dbf or *.dat – database files
- *.txt – ASCII text with no formatting (bold, underline,
and so on.)
- *.exe and *.com – executable programs
- *.sys – DOS or Windows driver files
- *.dll – Windows dynamic link libraries
- *.htm or *.html – Internet Hypertext Markup Language (web
page)
- *.ini – Windows or other configuration files
- *.rtf – Rich Text Format (a safer form of word
documents that has no macros but retains page formatting)
- *.wks, *.wk1 – Lotus 123 spreadsheet files
There are many more extensions that describe other types of
file formats:
- *.bmp, *.jpg, *.mpg, *.gif, *.tif, *.pcx – Image files
- *.ppt – Power Point
- *.wav, *.mp3 – Sound
- *.log, *.bat – batch files or Log files
