# BinaryFileFilter Task Parameters

The parameters in this section customize the `BinaryFileFilter` task.

This task rejects any documents that have been filtered as binary. This can occur when the file associated with a document is corrupt and KeyView filtering fails. When CFS detects a non-UTF8 character, it replaces the character with a hexadecimal character code. The `BinaryFileFilter` task detects these character codes and rejects documents where the proportion exceeds the limit set by the ThresholdPercent parameter.

You must configure `BinaryFileFilter` as a Post task.

The task reads configuration parameters from the section of the configuration file that you specify in the `Post` parameter, for example:

    [ImportTasks]
    Post0=BinaryFileFilter:BinaryFileFilterSettings

    [BinaryFileFilterSettings]
    ThresholdPercent=10
    OnErrorIndexerSections=IdolErrorServer
    IndexDatabase=IdolErrorReview
