Windows 10: show length of .flv files in explorer

It only shows the length of mp4, mpg, and wmv files.

:)

 

No video length data in File Explorer

Recently, File Explorer doesn't show the "Length" data in folders optimized for Video files. This appears to only happen in folders with MKV files, and not MP4 files, but it's not all MKV files. Some folders show the length data for all the MKV files,
some show data for some or just a few files, and some folders don't show any length data for any MKV files. I've viewed the folders from multiple PCs and have copied the folders to multiple PCs, and it doesn't seem to make a difference. Stranger yet, when
initially converted some of the files showed length data in File Explorer, but now do not. Any ideas as to what's going on with File Explorer in these cases?

the video's are on local drive

the controls show up for .MP4 but not .flv

and the MP4's don't change from file to file but they do change for .flv ?

 

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!

 

I have the current codec pack, and I can play all videos, but the length of flv files still doesn't show up in window's explorer. It does on other versions of windows.

 

Maybe the flv files are associated with another application. Change them to open with Media Player Classic and the could report their length.
