The comparison criteria can be defined under the menu item "Tools → Settings → Compare folders".
If the option "Show dialog with options" is checked there, the comparison criteria can be adjusted in the following dialog before the comparison is carried out:
If this setting and at least one setting for files are checked, files are compared.
File name
If this setting is checked, files with different names are assumed to be different. This option is available only if the setting "Files" is checked.
Ignore extension
If this setting is checked, when comparing files, the file extensions are ignored. This option is available only if the setting "Files" is checked.
File size
If this setting is checked, files with the same name are compared by their file size. If their file size is different, the files will be assumed to be different.
This option is available only if the setting "Files" is checked.
If this setting is checked, files with the same name are compared by the timestamps (date and time) of their last change. If the timestamps of their last change are different, the files will be assumed to be different.
This option is available only if the setting "Files" is checked.
If this setting is checked, only files with same MD5-checksums are considered identical, This option is available only if the setting "Files" is checked.
If this setting and at least one setting for folders are checked, folders are compared.
Folder name
If the setting folder is checked, the setting folder name is checked automatically and therefore folders with different names will be assumed to be different.
Folder size

This option works correctly only if the folder size is displayed in both panels (menu item "Folder → Size of folders" or the hotkey "Alt+F9").
This option is available only if the setting "Folders" is checked.
If this setting is checked, folders with the same name are compared by the timestamps (date and time) of their last change. If the timestamps of their last change are different, the folders will be assumed to be different. This option is available only if the setting "Folders" is checked.

Same
If this setting is checked, only items are shown, that exist in both panels
If this setting is checked, the comparison of the timestamps (date and time) of the last change to files and folders will ignore a time difference of two seconds or less (this is important for the comparison of NTFS and FAT hard disks).
If this setting is checked, diacritical marks are ignored, Example: "a" is equal to "á", "ä", "à", "â", "å", "ă".
Show only selected items
If this setting is checked, only items selected by the comparison are shown. To show all items again, activate the menu item "View → Only selected items" or the hotkey "Ctrl+S".
