Usage

Warning:
Always remember that data should be backed up regularly. We take no liability for any data lost or damaged through use or misuse of this software.  We recommend that important data is backed up prior to the use of this software, and deletion to the recycle bin is always selected. Also, you should always check that your recycle bin is enabled in Windows' own settings (right click-properties on bin).

 Duplicate Cleaner looks for files on your hard disc that appear twice.  There may be a good reason for this - a program may require a file in a certain place to work.  If in doubt, do not delete a file!

 
Search Location - where to look.
First we need to tell the program where to search. On the 'Search Criteria' tab you can choose folders by clicking on the folder icon, or type in the name yourself. Add the folder to the search list by clicking on the 'Add Search Path' button.  All paths in this list will then be included in the duplicate scan.  The program will also search all subfolders contained within the folders in the list as well. If you don't want this to happen, untick the 'Scan all subfolders' checkbox.

 There are two modes of operation - File Search and Music Search.

 File Search

This default mode will scan any file according to the filter criteria you specify. You can choose from one of the preset filters (graphics file, MS Office files, Movies, etc) or you can type in your own.  The filters are separated by a semicolon (;).

You may specify to search for duplicates by any combinition of:.
    

            * Same Content (CRC 32 checksum)          

            * Same File Name

            * Same Size

            * Same Date (Note - this is the file's Modified Date)

Same content (CRC) is the default option. When this option is ticked files will be classed as duplicates if they have identical content. This means they could have a different date, file name, etc.

Music Search

This special mode will seach music files and read the extra information contained within the file - Song title, Artist, Length, Bit Rate, etc. The currently supported formats are MP3, WMA,OGG,APE and FLAC.  This information can then be used as an additional tool when deciding which files to delete.

You may specify to search for duplicates by any combinition of:.

            * Same Artist

            * Same Title

            * Same Album

Some examples:

I want to find duplicates that are exactly the same

- Select 'Same Content' only

I want to find different versions of the same named document

- Select 'Same name' only

I want to find if I have multiple copies of MP3 files

- Try Music Search with 'Same Artist' and 'Same Title' only checked.  You should also do a separate 'Same Content'  file search as well, to catch any duplicate files with missing tags.

Size Range

In both modes you can specify and minimum and maximum file size in KB (Kilobytes).  If this is set to 0 then it is ignored.

Scanning
Now you are ready to start the scan. Click on the 'Start' button to the bottom left to begin. This may take a while depending on the number of files in your folders and the size of the files. It may take longer to scan a networked drive than a local one.  A Percentage progress is displayed to the bottom left of the window.  Once the scan is complete a summary is displayed and any duplicate sets are show in the main window.  You can cancel the scan by clicking on the 'Cancel' button which appears in place of the 'Start' button once the scan is underway.  Note that this may take a short time to respond depending on the status of the scanning process.

Results
Results are displayed in the various tabs:

Duplicate files
The duplicate sets are listed here. They are divided into colour coded 'groups'.  Each item in a group is classed as 'the same' according your search criteria.
You can right-click on a file to get a context menu with additional actions for the selected file.

All Files Scanned
This is a list of all files included in the scan, with attribute information. Double click on a file to open/view it.

Zero Size Files
This is a list of files which have a size of 0, ie. No content. Technically, they are all duplicates.  They will be listed in the main duplicate files list if specified in the options.

Deletion of files
You can now select files to delete. This should only be done if you are sure that the deleted files are not required! If in doubt, leave alone. To mark a file for deletion, in the 'Duplicate Files' tab either click on the checkbox or use the right-click context menu. You can also double click on a file to open it in it's native application for further investigation.

The selection assistant can also help with the marking of files. It can-

* Select oldest or newest file date in each group

* Select smallest or largest file size in each group

* Select all but one file in each group

* Select everything

* Select nothing

Additionally, when in Music Search mode you can select for deletion by audio tags. Options are-

            * Keep highest bit rate

            * Keep highest sample rate

            * Keep longest length

You can also select by a pattern in the file or folder name. For instance if you want to mark everything contained in a 'temp' folder you can use the expression */temp/* in the Path section. Or to select all .bak files you could enter *.bak in the Filename section.

When you are happy with your selection, click on the 'Delete Checked Files' button to delete your selection. The files will be moved to the recycle bin unless otherwise specified in the options.

Exporting Scan Results

At any point after the scan your results list can be exported to a CSV (Comma Separated Value) text file which can be open in a spreadsheet or database program. Click on the 'Export Results' button and specify a file name.
