By default FileLocator Network opens files in their raw binary format. While this works well for text based formats other formats, such as Microsoft Office files, do not work as well. Extensions help FileLocator Network in processing non-text based formats so that their underlying data is correctly retrieved and searched.





FileLocator Network lists the default extensions available plus any IFilters specified in the IFilters tab.


To switch on an document extension simply check the box next to the extensions name. To have the extension apply to other file types add the extension for the file type to the list of file types.


Safe Mode


An extension is normally run in the same process space as the FileLocator Network Search Agent, since it is the fastest way to communicate with the extension. However, running the extension in the same process space does mean that if the extension has a catastrophic failure it can crash the Search Agent. To avoid crashing the Search Agent troublesome extensions can be run in 'Safe Mode', which causes them to run in their own process space, but it does mean that using the extension may slow the Search Agent.


Indexing Service Filters (IFilters)


While FileLocator Network provides extensions for some well know file types, e.g. DOC, XLS etc, it is sometimes faster to use Indexing Service Filters if they are available. The 'Use IFilter (if available)' check box instructs the Search Agent to try and find an IFilter on the remote machine and use that instead of the FileLocator Network extension if one exists.


Note: Using an indexing service filter does not require the indexing service to be switched on merely that the IFilter is installed on the remote machine.


Search Raw Data


If 'Search raw data' is checked FileLocator Network will try and search the underlying raw data of the file when the extension is not active. For file types where this is not desirable, such as encrypted files, uncheck this option to stop FileLocator Network from searching the raw data.
