# Media Library

### Opening the Media Library
You can open the Media Library from several places in the CMS:
* The **Media Library** button in the top navigation bar
* Any **Icon**, **2D Model**, or **3D Model** field inside a Display Rule editor
* Under Solution Details → App Settings → App Configuration → **App Categories.**
***
### Browsing and searching
All uploaded files are shown as a grid of previews. Hover over any file to see its filename, dimensions, and upload date.
Use the controls at the top to find what you need:
* **Sort** — order by filename (A–Z or Z–A) or upload date (newest or oldest first)
* **Type filter** — show only `.svg`, `.png`, `.jpg`, or `.glb` files
* **Source filter** — switch between your own uploads and the default MapsIndoors icon set. Default icons can be used freely but cannot be deleted
* **Search** — find files by name. Partial matches work — searching `off` will return `office.svg`, `offsite.png`, and so on

### Selecting a file
Click a file to select it — it highlights to confirm your choice. Click it again to deselect, or click a different file to switch. When you're ready, click **Select** to apply it.
***
### Uploading files
Click **Upload** to open your file browser and choose a file to add. A few things to be aware of:
* The maximum file size is **8 MB**
* If a file with the same name already exists, you'll be asked whether to overwrite it. Overwriting replaces the file everywhere it's currently used in your solution
* Filename matching is not case-sensitive — `Logo.png` and `logo.png` are treated as the same file
***
### Syncing media to other solutions
If you manage more than one solution, you can share media between them without re-uploading. Find the file you want to share, click the **Sync** icon, and select which solutions to sync it to.
If the target solution already has a file with the same name, it will be overwritten. If not, the file is simply added.
