The caching mode will determine how the client will refresh the content of the data source when changes are detected. On large data sources, caching is essential as it increases performance significantly.
This feature is only available when using an Advanced Data Source.
If the cache is outdated, press Ctrl+F5 to refresh the local cache. This will force the application to retrieve the entire content of the data source to recreate the cache.
The Caching mode option can be accessed via File – Data Sources – Edit Data Source – Advanced in an advanced data source.
|Disabled||Prevent an offline cache from being used.|
|In-Memory||Use the offline cache only for recent changes, but prevent it from writing on the disk (in-memory only).|
|File||Use the offline cache only for recent changes. The cache will write on the disk.|
The client cache is persisted to disk in %LocalAppData%\Devolutions\RemoteDesktopManager[GUID:DataSourceID]
There are three engines for the cache:
- SQLite (offline.db)
- MCDF (offline.mcdf)
- MCDF v2.0 (offline.mcdf2)
If using a version of Remote Desktop Manager prior to 11.2, the default engine will be the SQLite, in that case the database is encrypted using a non-portable computed key hash.
If using version 11.2 or newer of Remote Desktop Manager the default cache engine will be the Microsoft Compound Document Format (MCDF) files.
You can enhance the security of the offline file by setting the Enhanced security in File – Options – Security – Offline Security.
Depending on the configuration of the Caching mode & the Offline mode the offline file may still exist since the file servers as a dual purpose caching & offline line support.
