It is usually are movie files created for viewing in Quicktime. File Extension Mov will tell you that, as well as give you a quick introduction to .mov files and what usually happens when you try to open one from Windows File Manager and you don’t have Quicktime installed.

With the size of hard disks that come with computer or laptop systems these days it is not difficult to have almost every media player there is that can be safely downloaded from the internet.

File Extension Mov offers a free downloadable program on their website that they say can help you determine if you need any extra drivers or programs to run or open whatever files you have open on your computer.

In my opinion, however, unless the file is something you know you yourself created, or if it was from a reliable source, whatever is needed to open it is already on your computer. On a Windows system this would mean Media player to open video or audio files, Notepad to open any text files, or Windows write to open a document in rtf format. File Extension Mov may also help you find out which program you need, if in case you don’t have them on hand.

It just takes a bit of research and the right sources to make sure you get the right programs.
