changing file extension

i have uploaded a video off my mobile onto my computer, and the file extension was missing. I then accidently changed it to .JPEG instead of .MPEg and now I don't know how to make it a video file, as it won't open as anything, or in any program.

Windows is normally set to hide common file extensions. You need to check if this is the case.

Open Windows Explorer and select Tools; Folder Options; and under the View tab, look for "Hide file extensions for known file types". If the box is ticked, de-select it and check your file again. You will probably find it has a double extension (the original and the one you gave it). If so, right click the file, select Rename and remove your extension. Alternatively, if it genuinely doesn't have an extension, now is the time to type one in (a full stop immediately followed by the extension.

For example;

for me to highlight the dangers inherent in changing file extensions. If you inadvertantly use the wrong extension Windows doesn't know what to do with the content, and you end up with an unuseable file.

i knew this already, but on uploading my photots from my mobile to my computer, the fiole extension was actually missing anyway, and I did not know the file extension for videos. It was a silly mistake, I just needed to know how to change it.

All the videos ive recived from mobile phones have been a .3gp file which quicktime will open.
