Braille graphic saved in the QuickTac Alternative Graphic format and created by QuickTac, a program used to emboss a graphic as a tactile graphic; stores a braille drawing, which may include shapes, lines, and text.

A SIG file is similar to a .BMP file and is designed to be imported into other programs, such as Duxbury Braille Translator and Duxbury MegaDots, in order to complement text. You can import the file into a Duxbury .DXB file using the Duxbury Braille Translator. Once the SIG file is imported into the Duxbury document it can no longer be edited. NOTE: Duxbury MegaDots has been discontinued.

A SIG file is a small text file that can be automatically attached to the end of e-mail messages. It contains the sender's name and email address. SIG files are supported by most email programs and can be selected from within the "Create New" message window.

Depending on the context, SIG files may contain more than just the sender's name and email. In work-related emails, the signature may also include the name of the person's company, the person's title, and contact phone numbers. In casual emails, some people choose to include a quote or Bible verse in their e-mail signature.
