[Bug 1364941] Re: Win 8.1: Device becomes un-responsive during MTP transfer of multiple files

 

This problem seems to occur more with directory structures. I copied a
large series of files in the same directory and it worked ok. But when
the files are spread across a directory structure, the problem seems to
occur more quickly.

The music files I am copying have a directory structure:
artisit/album/tracks.

I will also do some more testing around the filenames/attributes to see
if there is anything that triggers it.
