Is there a size limitation on PDF when using Foxit PDF IFilter?

Yes. There is a size limitation caused by Microsoft Search Service.

Foxit PDF IFilter does not have any size restriction of the PDF and neither does the evaluation version.

You can change the size limitation in the registry if needed.

3) Get the current value of the MaxGrowFactor in the MSSConfiguration table by running:

    - $SSA.GetProperty("MaxGrowFactor")
