How to Find Duplicate jpg files across multiple hard drives

Jack Burn , Oct 01, 2006; 07:49 p.m.


I have a desperate need for software that will search all of the hard drives on my home network and find duplicate files. I have 4 computers on my home network, and each has two or three hard drives. Each computer may have 10 to 20 thousand jpg files, and many of the files are duplicated on different computer. The software needs to compair file name, file date, and file size, and maybe some EXIF metadata.

I plan to install a large network hard drive (500GB) so that I have just one place to store photos (jpg files) that everyone on the network can share. To do this I want to move all of our jpg files to the network drive, but I only want one copy of each jpg. All together there are over 60 thousand jpg files. If I can delete the duplicate files I think I can get that number down to 25 thousand.

After deleting the duplicate files, I then need to look at each photo and delete all of the bad ones. At that point I may be down to just a few hundred.

Any help finding a good program to do this would be appreciated.

I am not aware of any packaged software to do that, but I am sure you could get a simple custom script written for maybe $20 at rentacoder.com

Do you run UNIX or anything similar (MacOS X, Linux, Cygwin)? If so, `fdupes' works great,

Windows will ask you if you want to REPLACE the original or not far any given batch MOVE/COPY operation.

You could try www.tucows.com which has many free and shareware programs. I saw a few candidate programs by searching "duplicate" as a search term.

Imatch, from Photools (WWW.Photools.com), is an image management system and has the ability to find duplicates, catalog your work, create slide shows, etc. Works very well finding duplicates. Has a lot of other funtions as well. Great program. John

Ztree download a full function 30 day trial from their site. do this ( the trial will have a red block that goes away when you start to use the program)

I used xtree on networks ztree should work on networks , also. is a 32 bit and windows program, claims to log many many files. I have logged 130 gigs. supports long file names. kim henkel wrote a good program.

You can try Directory Report http://www.file-utilities.com/downloads/wdir.zip

It can find duplicate files based on the same name, size and/or CRC. All screens can be printed or saved to text, HTML, Excel or XML.

The trial version last for 10 days and is fully functional. So you have plenty of time to see if it meets your needs

You may want to try Thumbsplus. It will do a search based on similarity of images for jpgs.
