put .AVI films on my computer but when i copy them to my FAT32 usb stick they will not play?
even when trying to play on the same computer
I came across this question a year on from your original post and had the same problem, but with music videos downloaded from Youtube.
Although the majority of files (.avi) would play fine on my PC from the original downloaded location on my PC, when loaded on to a USB memory stick, some would not play on my smart TV or with the stick back into the PC - with Windows showing an error, but with no definitive answer - as is often the case with Microsoft.
The only solution was to save the files already on the memory stick into a temporary folder on the desktop etc and then format the stick - transferring the saved files back afterwards. This worked for me. Hope it helps
anyone still tearing their hair out over this problem.
