(Blank)

Description

Lists types of files that cannot be used offline. The list stored in this entry overrides the system's default list of file types that are never cached for offline use.

This entry stores the setting of the Files not cached Group Policy. Group Policy adds this entry to the registry when you enable the Event logging level policy. If you disable the policy or set it to Not configured, Group Policy deletes the entry from the registry and the system uses the default list of non-cached file types.

By default, the system never caches files of the following types, as identified by their file name extension:

File type Filename extension
.SLM Microsoft Source Library Management file
.MDB Microsoft Access database file
.LDB Microsoft Access security file
.MDW Microsoft Access Workgroup file
.MDE Microsoft Access compiled module file
.PST Microsoft Outlook personal folder file
.DB? Generic database file

The list you create in this entry replaces the system's default list of non-cached files. Thus, to add a file to the default list, type a list that includes the default files and the type you are adding. To remove a file type from this list, type a list that includes all file types in the default list, except for the type you are removing.

The system maintains a list of non-cached files to protect files that cannot be separated, such as database components. Non-cached files are excluded from automatic and manual caching for offline use. The system does not cache files of the type specified even when they reside on a network share configured for automatic caching. Also, if users try to make a file of this type available offline, the operation will fail and the system displays the following message in the Synchronization Manager Progress dialog box:

Files of this type cannot be made available offline
