I have some home videos on my dropbox as mp4s, I wanted to download them again. I found the speed to be about 20KB/sec. However I noticed that if I renamed the file extension from mp4 to something else like dmg then it downloads much faster (like 200-500 KB/sec).
Is there something that can slow down files that appear to be videos. Renaming the file's extension doesn't affect the 1s and 0s, so it seems renaming should have no affect on the speed?
