File type is just an extra few letters on the name, e.g. thistextfile.txt. It has no real meaning beyond being a useful visual aid for the system user. If you want to show all types in Windows explorer then select the Folder options in the Tools menu item, and uncheck the selector titled "Hide extensions for known file types". To get the information in a Java program you would need to get a list of all the files in your directory and separate the extension field from the path name.

Solution 1

to identify the type of file we must know the MIME Type of the file . While going through the java api i found javax.activation.FileTypeMap. This class has methods, by providing the file object it return the file mime type.

See can this suffice you requirement.
