Recently copied some files (photos and videos) from phone (Android) to laptop (win7) to USB HD (WD passport) to desktop (Win7).
All the files have appropriate sizes, but attempting to open any of them gives a message that they are corrupted. They all have a string appended to their extensions of space, vertically centered dot, space.
Removing the extra characters from the extensions does not fix the problem. Does anyone know of a cause, or more importantly, fix for the situation?
