I use to try to keep files in specific folders etc. but it really was just the digital version of a shoebox. I have since started using Yojimbo about 6 months ago. I put nearly all my files in it with. Some things I tag but even if I don't, I can do a keyword search and find anything I need pretty quickly. The only feature I still wish it had was OCR support for pdf's. What are you guys/girls doing to stay organized??
