I downloaded an MP4 video file on my work laptop (Windows 7) and was able to open and watch it on Windows Media Player. I copied the file onto an external memory drive to watch the video at home but when I open the drive on my personal laptop (Windows 10) the file changes format to XML Document. I cannot open it on either Windows Media Player or on VLC. On Windows Media Player I am getting the "unsuported file format " error message. I took the external memory drive back to work today to check if I maybe copied the file incorrectly; however on work laptop the file shows as MP4 video. I don't know why it's not showing as MP4 on my personal laptop. I just purchased my laptop a few months ago so the technology should not be outdated. I don't believe the file is corrupt as it opend on work laptop with no issues. Please help!!!
Can you go to Settings> System>default apps>default apps by file type and see what it shows for .mp4?
Hi aardvark, thank you for your reply.
It shows Films & TV next to MP4:
Just changed it to VLC but it's still showing as XML Document
OK, just to be clear. When you transfer the .mp4 file to your laptop, it remains an .mp4 file type; correct?
Update: I'm not quite sure what you mean when you say it is still showing as an xml document. So, can you go to file explorer and show file extensions and then post a screenshot?
No, it shows as XML Document:
That's the Properties screen shot from the external memory drive. When I open the external drive on work laptop, type of file shows as MP4 but when I open on personal laptop it changes to XML Document. I tried to copy the file from external drive to my personal laptop but it just copies as XML
Holy moley? Can you try and play it right from the external drive to see what happens?
Scratch this request after reading your last post.
click CHANGE . next to where is says , OFFICE XML Handler and choose VLC
I tried that already but VLC doesn't open the file at all and Windows Media Player gives this message:
It's the most bizzare thing! have no clue what is going on!?
Hi caperjack,click CHANGE . next to where is says , OFFICE XML Handler and choose VLC
Tried that also and no luck - VLC still won't play the file. Under Type it says XML File but when I try to open with VLC it won't play.
UPDATE: Here's the Properties screenshot after I changed to VLC:

Should that box be unticked?
