    Video files won't play: is this an indexing problem?

    I have a folder of mp4 files on my hard drive, contained in a dozen or so subfolders. When I single click on any of them, the Windows 10/Explorer info pane (or the file in 'details' view) shows not only the file size but also the length, frame width & height, frame rate, data rate, bitrate and a video thumbnail. I have just copied the files over to a flash drive so that I can plug it into my TV and watch the videos there.

    I suspect that I messed things up though by deciding, half-way through copying these files (over 100 gigabytes worth), that I did not need to have Windows index the files on the flash drive, so I turned Indexing off for the whole drive in the properties box. Now files on the flash drive copied there after that point (I assume, I didn't note timing specifically, but seems very likely that was the cause) no longer show any of the video information I mentioned above, just the file size (+ rating & date modified & created); no thumbnail (screenshots). Now, unlike the files with all the data showing, or the ones on the hard drive, which open immediately in VLC Player for instance, these mp4 files cause VLC to hang - and worse, they will not play on my TV either ('unsupported format'). The MP4s that show the video data in Explorer, as above, all play perfectly, in VLC and on the TV.

    I had no idea turning off indexing would be so crucial (as I wanted the files for the TV, not PC). I have turned indexing back on for the whole flash drive , and checked in Indexing Options that the drive is included: I tried the 'modify' option + 'OK" and Indexing was running for a time, then showed 'complete'. But the same mp4 files are still missing the video data in an Explorer window, and will not play in VLC (odd) - even when I delete them and recopy them from my hard drive they end up with no video data (unindexed??) or on the TV .

    How do I resolve this, does anyone know? If I can force Windows to show the video data (does that come from the indexing service in Windows??), I imagine the files will then work in VLC and on the TV. If I make a second copy of one of the files that plays fine on the flash drive, back onto the flash drive again, that second copy is now a 'bad' one - no data shows and won't it play.

    I hope I don't have to start over from scratch, reformatting the drive and copying them all again - it took forever!

    Thank you!!

    Yes, I imagined it to be a Windows problem really, but I will do that (now you mention it, I remember I am already a member there in fact - a long time since I visited the site, but I can still log in - I just tried). I'll check back here too though in case anyone has any ideas.

    Thank you.

    The drive is faulty, I have ascertained. Returned for a refund, at least..

    Just a note: indexing would have nothing to do with whether a file is playable.
