How to get rid of unsupported format warning when copying files from Windows to Android device?

Question

Android

This warning pops up every time I try to record a video from a computer (Windows 7) to an android phone (Android 4.1).

There is a choice to copy or not. Another option - depending on the file format, it may offer to convert (to WMV) and the choice will be to copy as is or convert.
It swears at absolutely all files, except for the very WMV that it does by itself if you agree to the conversion. The file can be "as simple as five kopecks" baseline MP4, which even a standard player reads perfectly (not to mention VLC) - it still swears at it.
Not that it was very annoying, but somehow I want to turn off this nonsense if possible. Tell me how. Thanks in advance.

Answer 1

check the pc for viruses, because something stubbornly wants to run these files on the pc

Answer 2

this is what it is.
