File deduplication policy settings
Identical files can exist among various user profiles in the user store. Having duplicate instances of files stored in the user store increases your storage cost.
File deduplication policies let Profile Management remove duplicate files from the user store and store one instance of them in a central location (called shared store). Doing so avoids file duplications in the user store, thus saving your storage cost.
