There are 3 states to files in HCP Anywhere:
1) Save local - PINNED to desktop for offline access
2) Cached - locally available for temporary use - when reading a file or updating a file
3) Stubbed - pointer to a file in HCP Anywhere
When you read a stubbed file it is brought into the client cache for access on the desktop. When you write or modify a file on the desktop it is stored in the cache and saved to HCP Anywhere.
In addition to SAVE LOCALLY setting, the admin can control the cache size. It is can small or large. This determines how many files are stored temporarily for the user.
Also, we have a new setting in AW 3.1 Hotfix1 that allows customers to clear the cache on logout.
