To manage and organize my photo collection, I use...

Anyone can post in this thread and vote in the poll, even if you're not registered. But registering is recommended.

Windows Explorer. It can do what most or all of those other options can do, if you learn how to use it. ;))

Why add 3rd party software if you don't require it. :D

Photshop Elements Organizer. By using "tags" you can view sets of pictures in many ways.

This is similar to an earlier poll asking pretty much the same thing?
I suggest the multiple choice option be enabled for polls such as these because more often than not, singling out one option is not an accurate reflection of common workflow.
I haven't voted because I use both options. In fact, I'd not be surprise if everyone actually uses both at some stage of their photo management workflow.

I agree with sledger. I use BibblePro (on a mac) and finder to organize photos. It would be interesting to know what alternative software is being used and if there is a difference between amateurs and pros in their choice. I have voted though :)

In most cases I use XnView. :)

Adobe Bridge. Awesome for just this sort of thing.

Google Picasa for the excellent face recognition feature and to publish on-line albums.

XnView for quick browsing pictures.
