In order for MantaDB to be able to index a file it has to be able to separate the words from the remainder of the information. File processors must be specifically written for each type of file format. Having said that, there are many files of differing types that can use the same file processor.
Text files are the classic case.
They are listed, along with a more detailed description of the files they support, on the File Processor Overview page. Installing a New Processor Download the zip archive from the File Processor Overview page and unzip it to a temporary directory. Copy this processor dll file into the MantaDB home directory. The MantaDB home directory is the directory which contains the other MantaDB executables such as MantaSV.exe and MantaCL.dll. The readme.txt file contained in the zip archive will have further information about the capabilities of the file processor.
