Repository
Tap 
Repository and then you can tap to drill-down through all the content
available to you. The repository is particularly useful if you want to find content outside of
site document libraries, such as in wikis.
Sites
SkyVault sites are where content is directly stored and are the quickest way to access content.
Tap 
Sites and you’ll see a list of sites that you’re a member of
(My Sites) with the account you’re currently using. You can filter the
view of sites you see to your Favorite Sites, or use the Site
Finder to search for sites.
Tap 
next to a site for options
to join or leave a site, favorite/unfavorite a site that you’re a member of, and view the site
members.
If you have multiple accounts set up in SkyVault Mobile, first select the account you want to use. Tap on a site to view its document library and navigate through the folders until you find the item you’re looking for.
See Searching SkyVault for more on finding content.
