Are your IFilter products compatible with Windows Search service?

All our IFilters can be configured to work with Windows Search. You will need to configure custom temporary directory for each IFilter as described below:

  1. Stop Windows Search service.
  2. Open registry key "HKEY_LOCAL_MACHINE\SOFTWARE\IFilterShop"
  3. Open registry subkey related to the particular IFilter product
  4. Add new String value named "TempPath" and enter the full path to the new temporary directory.
  5. Start Windows Search service.
All IFilters can share the same temporary directory. Please note that when using custom temporary directory, we recommend that you set it as "not indexable" in all your indexing products. Otherwise temporary files may be indexed. This will pollute the index and also can prevent temporary files from proper removal by an IFilter.


Normally our IFilters install and work transparently, without any need for further configuration. If you are experiencing difficulties, try the steps below:
