Managing assets
Browsing assets
You can browse the Magnolia DAM in three views:
Tree view displays a hierarchical tree, including the folder structure.
List view displays the items individually.
| You can sort them alphanumerically by clicking the column headings. |
Thumbnail view displays thumbnail images of the assets. There is a zoom control at the top for resizing.
How to handle large amount of assets
The DAM can handle a very large number of assets. However, if you have more than 20,000 assets, you should organize them into folders. If your number of assets drastically exceeds the 20,000 guideline, we recommend that you use an external storage system with our DAM Connector Pack, our DAM API, or one of our Incubator modules extensions.
As a rule of thumb when using JCR for assets, you should keep it to about 500 assets per folder. This is independent of the asset type. So, whether it’s an image, pdf, or some other type of asset, let’s try to keep it under 500.
Avoid storing too many assets in the same folder. Instead, create subfolders and organize your assets. Storing too many assets within the same folder may lead to performance issues. If you need a large and unstructured flat list of assets, disable the thumbnail and list views.

Character restrictions
Website content, asset, configuration and everything else is stored in the content repository. Each item is stored in a node. The node name is generally displayed in the first column in AdminCentral, for example the page name in the website workspace and asset name in the dam workspace. Besides being an internal reference to the node, the name is also used for various purposes such to create a page URL.
Character restrictions apply only to node names and not to other user-entered content. For example, you can only use certain characters in a page or asset name but any character in the page or asset title. When a disallowed character is used it is automatically substituted with a hyphen (-).
The info.magnolia.cms.core.Path class governs
character restrictions. All alphanumeric characters (a-z, A-Z, 0-9), hyphen (-) and underscore (_) are safe to use in node names. We recommend that you use lowercase letters separated by a hyphen.

Apart from the exceptions above, Magnolia allows you to use the full UTF-8 character set for node names and other properties, but UTF-8 encoding is disabled by default.
See UTF-8 in pages names for instructions on how to enable it. When enabled, all special characters and notations covered by the Unicode specification can also be used.
The dot character (full stop, Unicode 2E) can be used in node names with the single limitation that it cannot be the first character. You can create a user john.smith, a page article.one, a document Magnolia-Flyer-4.0.pdf, a configuration node option.one or a JavaScript file jquery.tabtree.
