Hidden Folder - Missing Parts of Files

[Triple-X]

I have some private movies on a hidden folder, and when I hide/unhide the folder to watch, some of the movie shortens. It's really supposed to be longer, but it stops after about 1min. Each movie does about the same thing. If I fast forward by clicking like the middle of the movie (windows media player) it gets further, but still stops a little bit later without showing the full movie. Anyone know what's going on?

are they shortcuts perhaps?

No they're not.

 

[Osiris]

if you place them somewhere else will they play the full length? Can you take a known full movie, place it inside the folder and play it?

If I take the movie out of the folder, it plays the same. If I put one in, it does play normally. What could be the problem?
