Duplicate cleaner FAQ:

Should I scan my entire hard drive?

It's generally not a good idea to run Duplicate Cleaner over your system files, applications, or anything that you might not be sure what it is for.
Duplicate Cleaner is at it's most useful when used on your own data - Documents, Photos, Music, Movies, Code files, etc. This way you can make an informed descision when deciding what to delete!  Your My Documents folder is a good place to start.

Why is it taking a long time to scan?

Duplicate Cleaner is generally limited by the speed of your hard drives/network drives.  If there are a lot of identically sized files the software will have to check each one down to the byte level - this will take time.

I have lots of duplicate files found- which ones should I delete?

As a general rule you should only delete a file if you know what it is.  If you think you might need it then keep it!  It is always a bad idea to delete files from your Windows and Program Files folders unless you know what you are doing.

I can't delete a file because it is protected?

This is because you have ticked one of the settings in the Options menu -
Protect Windows/Program Files, or Protect DLL/EXE Files.  You should only delete these type of files if you know what you are doing.

I get access or permissions errors when deleting a file?

Try running Duplicate Cleaner as administrator.  In Vista or Windows 7 you can right click on the Duplicate Cleaner icon and select "Run as Administrator".

What is a (MD5, SHA-1) hash?

A Hash is like a fingerprint for a file.  Duplicate Cleaner compares these 'fingerprints' to help it identify duplicate files.
