Computer viruses get more and more intelligent every day, trying to sneak into your system under the disguise of innocent image files. Another problem may arise when you have a file without extension, or you can't open it with the program it is supposed to be run with. To find out what those files are really are you can use File Investigator.
     File Investigator is a tool that identifies a file by its content rather than its name. This program recognizes more than three hundred different file types and lists all available information about a specified file. The program can be accessed both from the command line with parameters (path to file) and the context menu.
     The program window consists of four tabs: Details, Background, Preview and Setup. The Details tab lets you view information about the file type - declared and real, comments and more. The Background tab provides information on what applications may be used to open this type of file - though it is somewhat out of date. The Preview tab lets you view the contents of the file and the Setup tab provides access to the program settings. This program is freeware, but a nag window is displayed on startup, urging you to purchase advanced versions of the application. Download it today and check it out yourself.
