This feature of Acrobat Pro is especially useful for academics - how many times have you downloaded an older journal article and found the PDF contained images rather than text? Not very useful when you'd like to search for key words rather than read through every potentially relevant article. With the excellent OCR (optical character recognition) technology available in Adobe Acrobat Professional, I was even able to recognize the text in the scanned documents, enabling full-file searching in modern operating systems (e.g., Windows 7, OS X, most Linux distributions). (Also, the papers were starting to pile up and turn my office into a huge mess.) My solution was to scan my paper files and organize them digitally.

Even if every single document I had saved was incredibly useful, they'd never be useful if I couldn't find the right file at the right time.

Several years ago, though, I realized that my filing system was a mess, and it was time to go digital. If it seems like a document might be useful to me at some point, even in the very distant future, I keep it.
