What is a .bin document?

.bin are binary files, they are used for lots of things like to save images, cd's etc. These types of files can sometimes hurt your system by running them if they are corrupted. What you should do is right click on it and go to properties to check what program created it. If the .bin file is accompanied by a CUE file you will have to burn it in order to run it. You might also want to visit www.filext.com to find out more about these files.

The suffix .bin is often used to identify a binary file (as opposed to a text file). A frequent use of the suffix these days (epecially since you mention a movie trailer) is in combination with a .cue file.

You can usually use the two files to burn a dvd/cd. To burn these, select "burn from image" in, say Nero or EasyCD, and click on the .cue file. This tells the program how to burn the .bin.

However, if you do not have the .cue file, a program called winISO will extract the data from the .bin and make it into a burnable ISO image.

Hope this helps.
