So, I have a SanDisk ULTRA USB 3.0 Flash Drive, I have some files in it (mostly avi and .TS files from my cam and some editing)...

I have checked the files on my PC and its there. But when I plug it onto my friend's laptop, the file isn't there and it shows that there is no "used space"...

Panic, then I rushed to my PC and the file is still there...

What is happening?!

Btw, I use WinXP and my friend's laptop is Win 8.1 , I tried copying other files, and they shows... only this .AVI and .TS files aren't. (but other type like MKV are shown too)
