Hi Rodrigo,
We understand it can be frustrating when trying to find the path of the Windows 10 edition Minecraft executable.
I recommend bringing up the start menu then doing a search for Run. Afterwards, type
%appdata% and it should show .Minecraft in a
roaming folder.
There is also the option of starting up Minecraft, on the main menu, go to mods and texture packs then open 'open texture pack'. That will open the file browser to the texture pack directory, which is a sub-directory of the .minecraft
directory.
Please check out the following link:

I hope this helps :)
