When logged into my.pogoplug.com, type your query into the Search bar at the top left. From there, select the file or folder you are looking for.
Selecting ‘Show Folder’ from the dropdown menu beside each search result will take you to that file or folder’s location.
If you use Pogoplug Team, you have additional options. Clicking the arrow next to the search icon lets you can select which types of files you would like to include in your search: your files, team folders or all files.
