#### Shared folders on demand

On Windows, you can share a folder "on demand" the first time a particular folder is used by a container.

If you run a Docker command from a shell with a volume mount (as shown in the
example below) or kick off a Compose file that includes volume mounts, you get a
popup asking if you want to share the specified folder.

You can select to **Share it**, in which case it is added to your Docker Desktop Shared Folders list and available to
containers. Alternatively, you can opt not to share it by selecting **Cancel**.




### Proxies

Docker Desktop supports the use of HTTP/HTTPS and [SOCKS5 proxies](/manuals/desktop/features/networking.md#socks5-proxy-support).

HTTP/HTTPS proxies can be used when:

- Signing in to Docker
- Pulling or pushing images
- Fetching artifacts during image builds
- Containers interact with the external network
- Scanning images

If the host uses a HTTP/HTTPS proxy configuration (static or via Proxy Auto-Configuration (PAC)), Docker Desktop reads
Title: Docker Desktop: On-Demand Folder Sharing and Proxy Configuration
Summary
The text describes Docker Desktop's on-demand folder sharing feature on Windows, where a popup prompts the user to share a folder when it's first accessed by a container through a volume mount. Users can choose to share the folder, adding it to the Shared Folders list, or cancel. The section also introduces Docker Desktop's support for HTTP/HTTPS and SOCKS5 proxies for various operations like signing in, image management, container networking, and image scanning.
