You can access these settings in the **Settings** application under the **Content ->** **Media** category. | General | | | -------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | Max subfolders | The maximum number of folders that can be displayed under an expanded folder node in the tree view. | | Enable media files usage tracking | **Note:** This setting is only available after applying [hotfix 13.0.85](https://devnet.kentico.com/download/hotfixes) or newer. In older versions, media files usage tracking is always enabled.
Enables a search index that allows users to find where individual media library files are used within the system's content. For example, the usage of a media file should be checked before a significant update or deletion of the file.
See: [Viewing media files usage](https://docs.kentico.com/13/managing-website-content/working-with-files/media-library-files/viewing-media-files-usage.md) | | Security | | | Media file allowed extensions | A list of file extensions that can be uploaded to [media libraries](https://docs.kentico.com/13/managing-website-content/working-with-files/media-library-files.md). Separate the extensions by semicolons.
See: [Configuring supported file types in Media libraries](https://docs.kentico.com/13/configuring-xperience/configuring-the-environment-for-content-editors/configuring-media-libraries/configuring-supported-file-types-in-media-libraries.md) | | Check files permissions | Indicates if the "See media library content" permission is checked for users who view media files through permanent URLs (see [Displaying content from media libraries](https://docs.kentico.com/13/developing-websites/retrieving-content/displaying-content-from-media-libraries.md)). | | Storage | | | Media libraries folder | The folder where [media library](https://docs.kentico.com/13/configuring-xperience/configuring-the-environment-for-content-editors/configuring-media-libraries.md) files are stored. You can use:
**physical disk path** – e.g. c:\myfiles\mysite
**root-relative path** – \~/UploadedFiles
**UNC path** – \\\server\folder
If no value is entered, the default location is: **\~//media**
**Note**: When you change the location of the media library folder, the system does NOT automatically move existing media files and sub-folders to the new location. To ensure that your media content is accessible and works correctly, you need to manually move the files from the old location to the new one in the file system. | | Use site-specific subfolders for custom media libraries folder | This setting is applied only when a _Custom media libraries folder_ is configured. If enabled, media library files will be stored in a sub-folder named as the site code name under the custom files folder, i.e. _/_. It is useful for better orientation in files when multiple sites are running in the system. | | Media file hidden folder | Name of the folder where thumbnails of media files will be stored. This folder is hidden in the file system by default and thumbnails are generated within it. | | Media file thumbnail suffix | Suffix added to thumbnail files. The thumbnail file names are in the following format:
