# Create and change connection files

| Show All

Remote Desktop Connection saves your connection preferences to a default connection file. To save time when you connect, you can save additional computer names and connection preferences for each Windows-based computer that you connect to. For example, you can choose to share all Mac disks when you connect to one Windows-based computer, and only a single Mac folder when you connect to a different Windows-based computer. You can also save different connection files for the same Windows-based computer.

Do any of the following:

| ##### Create a connection file

1. On the RDC menu, click Preferences.

   Note You are not required to type user information in the Login pane to continue setting preferences.

2. Select the connection preferences that you want for this connection, such as screen size, automatic login information, and security options.

3. On the File menu, click Save As.

4. Type a file name for the connection file, and then click Save.

   When you establish a connection, the options that you selected become the default preferences for all Remote Desktop connections.

Tip To quickly connect to a Windows-based computer, double-click the connection file, or drag the file onto the Remote Desktop Connection icon. Connection files are saved in Documents/RDC Connections.

| ##### Change a connection file

1. In Remote Desktop Connection, on the File menu, click Edit a Connection.

2. Select the connection file that you want, and then click Open.

3. Make the changes that you want.

4. On the File menu, click Save.

   When you establish a connection, the options that you selected become the default preferences for all Remote Desktop connections.

   Tip You can also change connection preferences while in a session. On the RDC menu, click Preferences, and then make the changes that you want. Changes take effect the next time that you connect.
