This section explains which settings are available with Photo Deduplicator.
Photo Deduplicator comes equipped with a Profile feature that allows you to have several sets of settings in parallel. This allows you to quickly switch between different settings. Settings that are Profile dependent are:
The following features are available for working with a Profile:
While there is some level of standardization of EXIF, TIFF and other metadata properties, by far not all camera or tool vendors comply with it. This results in different metadata property names used for the same logical information – e.g. in some cases the timestamp of when a photo was taken is stored in the property named "DateTimeOriginal" and the timezone offset is stored in "OffsetTimeOriginal", but Canon, for example, has decided to store the latter in the property "TimeZone" instead, and some video formats use "CreateDate" instead of "DateTimeOriginal". To be able to determine a photo files creation time properly, it is possible to provide alternative property names that Photo Deduplicator will use if the standard properties can't be retrieved from a particular input file.
The properties listed are default properties that Photo Deduplicator relies on to understand the creation timestamp of your photo or video files. he alternative property names on the left to each default property are the most common alternatives found. Should you run into a situation where your photo or video files' creation date (expected property is "DateTimeOriginal") is apparently not properly detected, check if your camera perhaps stores this information with a different name. You can then add this property's name – separated by a comma – to the list of alternatives, and retry.
If you change the list alternatives for a property, you have to reload all input files to have those changes take effect. This will not happen automatically.
Normally, you shouldn't be concerned about any of this – in particular if you only use folders – not individual files – as input to Photo Deduplicator: When selecting a folder as input for Photo Deduplicator, you have implicetely granted access to all files and sub-folders within that folder, and hence Photo Deduplicator can do its intended job without any access problem. If you decide to drag & drop or select individual files as input though, things can become more tricky. Because selecting individual files does not allow you to make any changes to their enclosing folder. But moving an input file somewhere else is already a change of that folder and that is not allowed by default. So you need to provide explicit access rights to the folder – or any of its parent folders – containing those files in such cases. Photo Deduplicator checks whether – depending on your intended operation – the necessary access rights have been granted and only then allows you to press the "Start" button. It will provide you with a hint about an access problem for a certain operation otherwise.
Application Sandboxing: Like any other application distributed through the Apple App Store and hence being "sandboxed" for security reasons, Photo Deduplicator needs to be explicitely granted access to the file system to perform its file operations. Sandboxed applications can only access files and folders – and sub-folders of these folders - to which you as a user have granted access rights. This is usually accomplished in two possible ways: either the application presents you with a File or Folder Picker dialog and asks you to select files or folders for performing a certain action (e.g. reading the file's content, renaming the file, changing its content or file properties, etc.), or you drag & drop files and/or folders onto the application and implicitely grant access to them. The access right for such folders or files by default ends with the running application being quit: if you restart it afterwards, the access right is gone again. But applications can also "bookmark" folders and files that you've granted access to before – Photo Deduplicator also does it. Bookmarking of security-scoped files and folders is required if you expect the application to re-open previously loaded files automatically when getting restarted. If you want to remove previously granted access rights again, Photo Deduplicator allows you to do so in the Settings section – so you remain in full control of what's allowed and what's not allowed.

Enable the Process sub-folders option to the right of the input folder field on the Home screen to automatically scan all folders of your external device (e.g. SD card).
