Can not open path with \ at windows 10

[hgyxbll]

I use sublime text and sublime merge, and they can not open path end with \(path at double quotation).
e.g.

>"c:\Program Files\Sublime Merge\sublime_merge.exe" "C:\Users\xxx\AppData\Roaming\Sublime Text 3\Packages\"

it think the path is C:\Users\xxx\AppData\Roaming\Sublime Text 3\Packages".

Sublime text version: 3176.
