Net Folders in Filr provide access to files on your corporate OES, Windows, Share Point, or NetWare file servers. In essence, a Net Folder is simply a pointer or a reference to a specific folder on a specific file server.
Configuring Net Folders in a sub-optimal way can result in unsatisfactory performance of your Filr system. The ideal Net Folder configuration can vary greatly depending on the number of files that you want to synchronize to Filr, the frequency in which files are modified, and so forth. Before configuring Net Folders, become familiar with the various subtleties related to Net Folders, such as the various synchronization methods and the impact of indexing content.
