show length of .flv files in explorer
It only shows the length of mp4, mpg, and wmv files.

To see the properties of all media files, there is a utility that is usually installed alongside K-Lite codec pack. If you haven't any other codec pack installed, it is a good idea to install K-Lite codec so you can play almost any audio and video format available and also have this utility. Then you can right-click on the file, select Media Properties (or similar) and see all the data you want, like resolution, frames per second, duration, video codec, audio codec etc.
Right click in the white space of any folder where the audio files are kept. View --> Details; then right-click on the field bar, click Length. This applies to Windows 7 which I use on three computers, Windows 10 may very well be different!
Maybe the flv files are associated with another application. Change them to open with Media Player Classic and the could report their length.
