Description
Returns the extension portions of a file name.
Use ExtractFileExt to obtain the extension of a file name. For example, the following code returns the extension of the file name specified by a variable named MyFileName:
MyFilesExtension := ExtractFileExt(MyFileName); // Delphi
MyFilesExtension = ExtractFileExt(MyFileName); // C++
The resulting string includes the period character that separates the name and extension parts. This string is empty if the given file name has no extension.
Note: This function works for multi-byte character systems (MBCS).
