Scan Criteria tab

The Scan Criteria tab is where you tell Duplicate Cleaner what you are looking for, and how you want to match duplicates. (The Scan Location tab lets you say where).
 
On this page you can set in what way you want Duplicate Cleaner to match files. You can also specify additional duplicate matching options and search filters - these narrow down the type of files you are scanning for. 
 
 
 

Mode of operation

There are four modes of operation -
 
 
Select the appropriate tab to activate this scan type, and then specify the criteria.  Only one scan mode can be active at a time.
 

More duplicate options

These are additional scan criteria relating to file and folder attributes that can be used with all scan modes.
 
E.g
“File - Copy.txt”
“File - Copy (1).txt”
“File - Copy (2).txt”
“File - Copy (3).txt”
“File (1).txt”
“File (2).txt”
 
So using this “MyFile.txt” can be matched to “MyFile – Copy(16).txt” when matching file names. Note this current only works with the English 'Copy' suffix.
 
Same file size - Matched files have to have the same size (in bytes).
           A matching tolerance can also be set. The tolerance can be set in Bytes, Kilobytes, Megabytes or by percentage difference.
Note: This is unavailable if the 'Regular mode' - 'Same Content' option is selected, as this type of scan already assumes the files will be the same size.
 
You can also set a matching tolerance in Hours, Minutes and Seconds.
You can also set a matching tolerance in Hours, Minutes and Seconds.
 
 
Is case sensitive - Checks are case sensitive
Similar text tolerance - Checking tolerance (lower is stricter)
 
 

Search filters

Search filters allow you to narrow down the files to scan before any matching takes place.  Having filters in place can speed up large scans.
 
File types
 
Having 'All file types' checkmarked will scan all the file types supported by the current Scanning Mode. (e.g. just image types for Image Mode).  Unchecking this setting allows you to set custom filters or use an editable preset.
 
You can choose from one of the preset filters (graphics file, office files, movies, etc) by clicking on the 'Presets' button or you can type in your own. 
 
Multiple filters are separated by a semicolon (;).  For example:
*.txt;*.bak;*.ini
 
You can also choose to exclude certain file extensions should you wish. This feature is most useful when a wildcard is used in the 'included' box.
 
For example:
Included: *.*
Excluded: *.db;*.ini
 
Additionally, folder names can be excluded from the scan. This option will apply to anything in the Excluded box (For example: .picasaoriginals)
The file presets can be saved and edited from the settings tab.
 
File sizes
You can set the file size range of the search (Minimum and Maximum). You can also set the units for this value (Bytes, KB, MB, GB or TB).  If 'Any file size' is selected then all file sizes are scanned.
'Ignore zero size files' will exclude all empty (zero bytes) files from the scan.
 
File dates
 
This allows you to search between certain file dates (Created or Modified). 'Any Date' will scan all file dates.
 
 
Image / Movie dimensions
 
This filter is for Image and Video modes. Here you can limit the scan to pictures or videos which fall between specified dimensions, in pixels (px).  'Any dimensions' will scan all sizes.
 
Hard-links
 
 
Hard-links are a way of having a single file show in multiple places on the file system. Hard-linked files may show up as duplicates, though they actually will only take up the disk space of one file.
