# DS file (Android)

DS file is ideal for managing files stored on your Synology NAS, such as uploading and downloading files between your NAS and Android device or perform basic editing tasks, through secure HTTPS connection. Additionally, DS file is useful for browsing pictures, watching videos, or checking work documents when you are on the go.

## Before You Start

Before using DS file, please make sure your Synology NAS device is running DSM 5.0 or later. Otherwise, certain features will not be available. Basic configurations must be managed from a computer with access to File Station.

## Login and Logout

DS file allows you to log in to File Station securely and effortlessly. You can protect your connection via SSL/TLS connections and verify the server certificate installed on your Synology server.

#### To log in to File Station with DS file:

1. Do either of the following:
   - Enter the following information on the login page:
     - Address or QuickConnect ID of the Synology server: This can be either the internal or external IP address, DDNS hostname, or Synology QuickConnect ID. To use QuickConnect ID to log in, make sure you have enabled it at Control Panel > External Access > QuickConnect (for DSM 7.0 and above) or Control Panel > QuickConnect (for DSM 6.2 and earlier) in DSM.
     - Your user account and password
   - Tap the arrow button next to the Address or QuickConnect ID field to select previous login credentials from the list of your login history or find Synology servers in your local network. A set of credentials can be removed by tapping on the right of the chosen entry and then Delete.
2. If you want to secure your connection, turn on HTTPS to use SSL/TLS-encryption.

#### Troubleshooting:

- If you are unable to log in, do the following:
  - Log in to DSM with an account belonging to the administrators group, and go to Control Panel > Application Privileges (for DSM 7.0 and above) or Privileges (for DSM 6.2 and earlier) > File Station > User to check whether the user account has permissions to use File Station.
  - Check if File Station is using a customized port. For example, if the port is 9920, you may need to add the port to the IP address/DDNS hostname as in "fun.syno.com:9920".

#### To use multi-factor authentication:

When multi-factor authentication is enabled or enforced by the admin, sign in to this app with Synology Secure SignIn or other third-party authenticator apps.

#### Note:

- When multi-factor authentication is enabled on DSM (6.0 and above), your mobile device can be remembered for convenient and safe login:
  - To have your device remembered, select Trust this device on the login page. Your device will be remembered for 30 days; if you log in again within its validity period, your device will be remembered for another 30 days.
  - To stop trusting the device, go to DSM > Personal > Security, click 2-Factor Authentication, enter your password, click Manage, and click Revoke Other Devices.

#### To simplify logging in:

You can enable Remember me on the login page to remember the password your user account. You will always be automatically logged in until you log out of the app. Note that enabling this option will only save the password for DS file but will not share it with other Synology apps.

#### To log out of DS file:

Simply tap > > Logout.
