I truly have a plethora of PDFs. If I printed all of them out, not only would I kill multiple printers I'd probably get fined for being a fire hazard. I have them on my hard drive, my back up external drive, a portable external drive, on flash drives, on SD cards, on my Sony 505 e-book reader, my Nokia 810 internet device, my iPhone... I'm sure I'm missing a thing or two on that list.
What does all that mean? It means I can rarely find the PDF I want when I want it.
Why? Because 9 out of 10 publishers of PDFs don't give it a descriptive title (something that Windows from XP on handles very well). Nope, instead of calling the file "Killer Dungeon for 3e ver a" they use "kd010" if you are lucky. Many times it seems its just a random selection of letters and numbers that leave you scratching your head as you open multiple PDFs in the hopes of finding the one that you've been hankering to read for the last 2 nites.
I know, I should be downloading in an orderly fashion to sorted folders just for that reason. It is not in human nature to do so... the vast majority of us dump our downloaded documents in the "Document Folder" and then curse our inability to navigate the sea of seemingly randomly named files.
I think I'll need to spend some time on my vacation sorting this mess out.
Then again, I'm the same guy who has hardly sorted out his bookmarks in Firefox. That's my own mess tho'. The PDF mess is not mine alone.
