A desktop computer is a personal computer designed for use at a single location due to its size and power requirements, usually by one person. The most common configuration has a case that houses the power supply, motherboard, disk storage (usually one or more hard disk drives and optical disc drives); a keyboard and mouse for input; and computer monitor and printer for output. The case may be oriented horizontally and placed atop a desk or vertically and placed underneath or beside a desk.

How to find and eliminate duplicate files on your Windows systems.
Finding and deleting duplicate (picture) files can be a time consuming task. My wife and I, our three kids and their families all share one dilemma: Managing our pictures. Between desktops, laptops, phones, tablets, and cameras; over the last decade or two, we've accumulated and shared many 10s of thousands of pictures. And in an effort to begin managing them, it seemed that finding and deleting duplicates was a pretty good start. Easier said than done.

About 8 or 9 years ago, I wrote a program that enumerated all files of a type (extension) in any drive (or folder). Once all the file names are "listed", I added a section to then get an MD5 hash of each file. As each file is hashed, it writes 4 pieces of data to a tab (or comma) delimited text file:
32h byte hash,  file size,  file name,  full file name.

1. Select Drive

When you run DupeFF.exe, all available drive letters will be listed down the left side - choose one.

2. Select a Folder

You can search entire drives, or select a specific folder. Whatever you select will be searched entirely including all sub-folders.

3. Select a File Type

You can search for any file type. If you want to select ALL files (all types),
click the last type "*" listed. Or select any other type by entering the extension where the "*" is. To select any excel spreadsheet type, enter "xl*" (it will find xls, xlsm, xlsb, etc.)

4. Click the #4 Enumerate File List button
