Find and Remove Duplicate Files to Free Up Hard Disk Space
. Duplicate File Finder
- This is the easiest software to find duplicate files and also with only a click of a button, it will remove all old duplicate files. Portable, simple graphical user interface and no configuration at all. The method being used to scan for duplicate file is raw binary comparison of the actual data inside the file. It is 100% accurate using this method. Original Files are determined by creation date, if it was created first, it is considered the original file. Took 2 minutes and 29 secs to scan 106GB (23950 files). Not able to select which folder to exclude scanning, so you have to avoid adding root of a drive to the path.

2. Heatsoft Clone Cleaner Lite
- Nothing much to configure. Just add the path that you want to scan and search. By default it protects Windows, Program Files and hidden folders. Took 2 minutes 5 seconds to scan 106GB (23950 files). It uses TABS to show you the scan result in same name, same size, same name and size, same content, full clones and zero size. It has Smart Mark where you can automatically mark the duplicate files to be deleted.

3. DupKiller
- DupKiller has all types of scanning methods. Same name, same date and time, same size, same type(extension), similar name and same content. The same content is raw binary comparison which is 100% accurate. Has very good exclusion option but unfortunately very slow in binary comparison. Took 4 minutes 55 seconds to scan 0.3% of 106GB (23950 files). It automatically saving and loading of previous scanned results by default. You can turn it off at the options page.

4. Easy Duplicate Finder
- Able to exclude system folders (windows and program files). It says that it search for true duplicates (files with same contents). Took 1 minute 46 seconds to scan 106GB (23950 files). This can be a really good duplicate finder BUT there is no way to easily select all duplicates and delete them with one click. It found 5809 duplicates on my computer and I am going to have a hard time selecting them one by one.

5. DoubleKiller
- Ability to scan for duplicates using names, sizes, dates and CRC32. All methods used here is not 100% accurate. CRC32 is not 100% because there is a very small probability of two files having the same checksum although they are not identical. If you want to use raw binary comparison, you need to PURCHASE the PRO version.

6. CloneSpy
- CloneSpy is another one that doesn't do raw binary comparison. It only compares checksums, same name and approximate size.
