Select the setting you want.
Manual caching of documents
Provides offline access only to those files other users specifically identify. This caching option is ideal for a shared folder containing files that several people will access and modify. Manual caching is the default option when you make a shared folder available offline.
Automatic caching of documents
Makes every open file in a shared folder available offline. Older copies of files are automatically deleted to make way for newer versions.
Automatic caching of programs and documents
Provides offline access to shared folders containing files that cannot be changed. This caching option reduces network traffic because offline files are opened directly without accessing the network versions. The offline files generally start and run faster than the network versions.
When you use Automatic caching of programs and documents, be sure to restrict permissions on the files contained in the shared folder to read-only access.
