Geez!! I didn't realize Explorer will show the total time of selected media files if you have Details Pane selected in Layout(or at least it does on both my Vista PCs but I have MediaInfo installed on each so I'm not sure who is doing what.)
-oh, how I have been struggling to figure out how to replicate this. I have fumbled for several hours with Vista Explorer, MediaInfo, and QTTabbar, but so far Vista will still only tell me "last modified date (period)". No 'Total Playtime' info!
What do you say, Miles; any idea how you've managed to have Explorer tell you the total playtime?
only MP3 files selected:
(see attachment in previous post)
I can't find where the setting is hidden but you need to enable Preview for the Explorer folder. That should give you a pane at the bottom and when media files are selected you get info including playtimes. I have MediaInfo installed with explorer extension enabled.
Edit: or just use skwire's PlayTime. I believe it's not in memory all the time. Just launched when you run it via shell extension or manually. And the shell extension works in both 32 and 64 bit. I have it on both Vista64 and W7 32 bit. It's more versatile than Explorer method because you can select some files, do Add To Playtime, then select more files in another folder and add them.
edit: ok, see from other posts you are already working with skwire.
Also I've tried several file types like .mkv and .m2ts and it doesn't seem to work with those afa display of total time or run times generally. It's likely .avi and a few other types. Best to go with PlayTime as Explorer looks like it will be imcomplete afa media file type support.
