the Following
Extensions
By default, the File Extension field lists the most common file extensions. You can
manually add or delete extensions. Use commas to separate different extensions. You
can enter a maximum of 40 file extensions. The maximum total length of this field,
excluding the delimiter commas, is 160 characters.
You can also use the drop-down list to add predefined file extensions from a specific
category to the File Extension field:
• None. No file extensions are added to the File Extension field. This is the default
setting.
• Executables. Executable file extensions (exe, com, dll, so, lib, scr, bat, and cmd)
are added to the File Extension field.
• Audio/Video. Audio and video file extensions (wav, mp3, avi, rm, rmvb, wma,
wmv, mpg, mp4, and aac) are added to the File Extension field.
• Compressed Files. Compressed file extensions (zip, rar, gz, tar, and bz2) added
to the File Extension field.
