Tags to scan:

When using the Tags scan type, you can select the tags that will be used for comparison.

Word weighting:

See Word weighting.

Match similar words:

See Similarity matching.

Match pictures of different dimensions:

If you check this box, pictures of different dimensions will be allowed in the same duplicate group.

Match pictures of different rotations:

If you check this box, pictures of different rotations will be allowed in the same duplicate group.

Filter Hardness:

The threshold needed for two files to be considered duplicates. A lower value means more duplicates. The meaning of the threshold depends on the scanning type (see The scanning process). Only works for worded and picture blocks scans.

Can mix file kind:

If you check this box, duplicate groups are allowed to have files with different extensions. If you don’t check it, well, they aren’t!

Ignore duplicates hardlinking to the same file:

If this option is enabled, dupeGuru will verify duplicates to see if they refer to the same inode. If they do, they will not be considered duplicates. (Only for OS X and Linux)

Use regular expressions when filtering:

If you check this box, the filtering feature will treat your filter query as a regular expression. Explaining them is beyond the scope of this document. A good place to start learning it is regular-expressions.info.

Remove empty folders after delete or move:

When this option is enabled, folders are deleted after a file is deleted or moved and the folder is empty.

Partially hash files bigger than:

Only used by the Contents and Folders scan types. Files bigger than this size are first compared by samples taken from a few places in them, so files that differ there are never read in full. This saves time on big files of the same size. Files whose samples match are still compared in full.

Copy and Move:

Determines how the Copy and Move operations (in the Action menu) will behave.

• Right in destination: All files will be sent directly in the selected destination, without trying to recreate the source path at all.

• Recreate relative path: The source file’s path will be re-created in the destination folder up to the root selection in the Directories panel. For example, if you added /Users/foobar/SomeFolder to your Directories panel and you move /Users/foobar/SomeFolder/SubFolder/SomeFile.ext to the destination /Users/foobar/MyDestination, the final destination for the file will be /Users/foobar/MyDestination/SubFolder (SomeFolder has been trimmed from source’s path in the final destination.).

• Recreate absolute path: The source file’s path will be re-created in the destination folder in its entirety. For example, if you move /Users/foobar/SomeFolder/SubFolder/SomeFile.ext to the destination /Users/foobar/MyDestination, the final destination for the file will be /Users/foobar/MyDestination/Users/foobar/SomeFolder/SubFolder.

In all cases, dupeGuru nicely handles naming conflicts by prepending a number to the destination filename if the filename already exists in the destination.

Allow marking reference files:

On the Advanced tab. When this option is enabled, reference files get a mark box too, so that every file of a group can be deleted, moved or copied. See Results for how marked references behave and how dupeGuru protects them.

Custom Command:

This preference determines the command that will be invoked by the “Invoke Custom Command” action. You can invoke any external application through this action. This can be useful if, for example, you have a nice diffing application installed.

The format of the command is the same as what you would write in the command line, except that there are 2 placeholders: %d and %r. These placeholders will be replaced by the path of the selected dupe (%d) and the path of the selected dupe’s reference file (%r).

If the path to your executable contains space characters, you should enclose it in “” quotes. You should also enclose placeholders in quotes because it’s very possible that paths to dupes and refs will contain spaces. Here’s an example custom command:

"C:\Program Files\SuperDiffProg\SuperDiffProg.exe" "%d" "%r"
