From windows Commande Help

Advanced

These advanced search options are only used in some special cases, for example if the date of a letter is known, but not its file name.

Field Meaning

Date between: These two fields allow to specify the period of time when the file was last modified. Only one or also both fields can be given.

Not older than: Allows to specify how old the file can be.

File size: Here you can search for files smaller or larger than a specific size

Attributes: Search for files with special attributes, like hidden, system, or for directories.

Duplicate file finder Searches the given directories for files which have the same name, size, and/or same contents. Only files occurring multipe times will be shown, grouped together by same files, and separated by a dashed line.
same name If checked, files will only be compared if they have the same name. If unchecked, the option 'same size' must be checked. Not checking 'same name' is useful to find e.g. identical backup copies.

same size If checked, files with the same size are considered to be identical.
same contents If files are found with identical size, they will also be checked for same content. Although this takes much longer, it ensures that the files are 100% identical.

If 'same name' is checked, the files will be sorted by name, otherwise by size, so identical files can be grouped together.
