Isso seria útil? É para uso no Vista então deve funcionar com 7
- Create a folder on your ordinary hard disc, “Shared”.
- Go into “Shared”, from a command prompt (Start->Run->cmd)
- Type “junction “Stuff” F:\My_Removable_Drive”
That creates a symlink called “Stuff” under “Shared”, which will point to F:\My_Removable_Drive
You can now share the folder “Shared” and have network access to your Removable drives whenever they’re plugged in, without having to tediously recreate the share every time.
