Which is why I keep no TIF files, unless I've made some serious changes in Photoshop. After using a TIF, I keep the RAW file which can be reconverted at any time to the original settings, and a small 40K JPG preview file for identity. This system makes a nice tidy and compact bunch of files to archive and backup. Here's a tip I'll give anyone going digital. Always keep the camera assigned file number in the filename no matter what other name you add to it. That way you can always find it later. I learned the hard way about this. My files end up something like oshidori_2036_web.jpg. I also file them in folders according to the year, month and day. I keep RAW files in a sub folder of each day. I backup only my RAW files and previews, plus extra copies in high quality JPG files of my best shots. It's a complicated thing, saving all these files, there's no way around that.
