This network location can't be included because it's not indexed.
Apparently, you can't choose to do the indexing on your Windows 7/8 system and that's that.
It took me some time to come up with a good solution, but the guys and girls at My Digital Life have put up a workaround. See the lower half of this page.
Here are the steps:
- Create a dummy folder with any name. You can use the same name with the network folder name.
- Add and include the dummy folder into the Library.
- Delete the dummy folder (it won’t be removed from the Library).
- Open an elevated Command Prompt window (Run as Administrator), and use the following command to make a symbolic link which links the dummy folder to the network location:
mklink /d "\full\path\to\dummy\folder" "\\full\path\to\remote\folder"
Change the "\full\path\to\dummy\folder" and "\\full\path\to\remote\folder" to actual full path to the folders. - Visit the Library, and the contents from the non-indexed remote location linked via symbolic link is now appearing inside the Library.
