Here are a couple pointers without purchasing extra software ....
One thing you can do is rename each image - changing the number to a descriptive name. Then you can quickly see what each image file is and the search funtion of windows explorer, etc. will let you search by name. Rename the image by right clicking on the name of the file and selecting "rename".
You can also view the photo folders as thumbnails, which gives you a quick view of all photos in that folder.
You can view several folders at a time like that by doing a search and seleccting all the folders you wish to see. Put nothing in the search fields and click on search. It will list all files in the selected folders.
I am sure someone else can point out some programs that can help in cataloging your photos. These are just a few quick, free tips.
