The Manage Media page has three columns of information:
- Media sources
- Missing media
- Uncached files
There are three types of location that Relative History can access in order to store and look for media files:
- Application storage
- One or more folders on the device
- One or more folders on OneDrive
The app matches media records to files by using the filename specified in the record (ignoring any path information to the file). It searches the folders in the order in which you specify them and you can re-order the list and then use the Rescan button to tell the app to re-match the media records.
The Application storage folder is private to the app. It is added by default because, initially, it is the only location that the app can save to. If you prefer to save your images elsewhere, e.g. on a different drive, you can specify that folder and then remove the Application storage folder.
You can remove any sources you no longer want to use. Note that you must have at least one source from the device that is running the app.
When adding a OneDrive folder, it is also possible to pick a folder that has been shared with you.
The integration between Relative History and OneDrive means that it is not necessary to have configured your device to synchronise the required OneDrive folders to your device first. The app is able to access files stored on OneDrive directly.
If you specify any OneDrive folders, you can get the app to cache copies of any files it uses from OneDrive. This is controlled in the apps’s settings. If you enable caching, the first folder you specify that is local to the device will be used to store the cached copies. Please note that only image files are cached.
If there are images associated with a given record, a thumbnail will be displayed instead of the default icon for that record type.
If the thumbnail needs to be rotated, tap on the item so that you can navigate down to the image itself.
You can then rotate the image clockwise or counter-clockwise on the screen, and the thumbnail display will rotate to the same amount.
You can also zoom and pan on the image this way, which is particularly useful if you want to read (for example) a certificate in more detail. The pan/zoom information is not kept when you navigate away from the image page.
For files that are not image files, the app will display an appropriate thumbnail and tapping to open the file will cause the computer to use the most appropriate method, e.g. your default web browser for URLs.
