I had an older program that I used to manage/file images (ie: both pictures and documents), that I scanned into my computer from my multi-function printer. What is the best program for me?
There are many alternatives nowadays that you can use for file management on your Windows PC. While the standard Windows Explorer does the job properly, you can use the two applications I have found to meet the needs:
