Adobe Acrobat very, very useful ...

I also bought myself the ScanSnap only without Adobe Acrobat, not least because the Publisher in many reviews as superfluous.
But this is not so! Only with the Adobe Acrobat can also be the contents of entire folders for keywords in "searchable PDF files" found. If you have Adobe Acrobat not, one has to rely on the Windows Search index - and is not nearly as good.

I have certainly bought later my Adobe Acrobat.
