To transfer files to Compute Engine instances, different options are available depending on your workstation OS and the target instance OS.

Transferring files to Linux and Windows instances
You can use Cloud Storage to transfer files across all operating systems.
Transferring files through Cloud Storage
Cloud Storage buckets can be a convenient intermediate transfer point between you and your instances, regardless of OS.
This file transfer method works on almost all operating systems and instance types as long as your instance has access to your Cloud Storage bucket through a service account or through your personal user credentials.
Upload your files from your workstation to a Cloud Storage bucket. Then, download those files from the bucket to your instances.
Create a new Cloud Storage bucket or identify an existing bucket that you want to use to transfer files.
From your workstation, upload files to the bucket.
Connect to your instance over SSH or RDP:
On your instance, download files from the bucket.
If you need to transfer files in the other direction, reverse the process. Upload the files from your instance and then download those files to your workstation.
Transferring files to Linux instances
Transferring files using SSH in the browser
If you can establish an SSH connection to an instance using the SSH from the Browser window, you can use that connection to transfer files to the instance.
- In the Cloud Console, go to the VM instances page.
-
In the list of virtual machine instances, click SSH in the row of
the instance that you want to connect to.
- After the connection is established, click the gear icon in the upper right
of the SSH from the Browser window and select Upload file. Alternatively,
select Download file to download a file from the instance.
- The transfer dialog opens. Specify which file you want to transfer.
If you uploaded a file, the file is in your user's /home directory.
If you downloaded a file, the file is in the default download folder on your local workstation.
Transferring files using the gcloud command-line tool
The gcloud command-line tool provides an SCP file transfer utility, creating
an SSH key pair for you the first time you connect. Your private key is stored
on your local device and its corresponding public key is copied to project or
instance metadata.
To transfer files using SCP, you must have a firewall rule on the network
that your instance uses that allows SSH connections on port 22. Read
Using firewall rules
to learn how to set the necessary firewall rules to allow these connections.
You can install
the gcloud tool and use it to copy files and directories to your
instance using the scp
command.
The following example copies a file from your workstation to the home directory on the instance.
gcloud compute scp local-file-path instance-name:~
Replace the following:
local-file-path: The path to the file on your workstation.instance-name: The name of your instance.
You can also copy files and directories from an instance to your local workstation. The following example recursively copies a directory from your instance (the source) to your local workstation (the destination).
gcloud compute scp --recurse instance-name:remote-dir local-dir
Replace the following:
instance-name: The name of the instance.remote-dir: The path to the directory on your instance.local-dir: The path where you want to put the directory on your workstation.
For more information, see the
gcloud compute scp
reference documentation.
Transferring files using SCP on Linux and macOS workstations
The scp command-line tool works similarly to the
gcloud compute scp command but requires you to
manually manage your SSH keys.
To transfer files using SCP, you must have a firewall rule on the network
that your instance uses that allows SSH connections on port 22. Read
Using firewall rules to learn how to set the
necessary firewall rules to allow these connections.
The scp tool uses the same key files that you use to
connect to your instances using standard SSH.
If you have not yet applied a public key to your Google Cloud Console project or instance, obtain an SSH key pair and apply the public SSH key file to your project or instance.
Find the external IP for the instance that you want to send files to. In the Google Cloud Console, go to the VM instances page.
Use the
scptool to copy a file from your workstation to the home directory on the target instance. For this example, the private key is at~/.ssh/my-ssh-key.scp -i ~/.ssh/my-ssh-key local-file-path username@ip-address:~
Replace the following:
local-file-path: The name of the local file that you want to upload.username: Your username.ip-address: The IP address for your instance.
You can also copy files from an instance to your local workstation by reversing the source and destination variables. For this example, copy a file from your instance to a path on your workstation.
scp -i ~/.ssh/my-ssh-key username@ip-address:remote-file-path local-file-path
Replace the following:
username: Your username.ip-address: The IP address for your instance.remote-file-path: The name of the remote file that you want to download.local-file-path: The location on your workstation where you want to download the file to.
Transferring files using WinSCP on Windows workstations
On Windows workstations, the WinSCP client lets you manage files on your instances through a graphical file browser interface.
WinSCP uses the same key files that you use to connect to your instances using PuTTY.
If you have not yet applied a public key to your Cloud Console project or instance, obtain an SSH key pair and apply the public SSH key file to your project or instance.
Download and install WinSCP. The default install settings work for most users.
Start the WinSCP program. A login window opens where you can configure your connection settings.
Find the external IP for the instance that you want to send files to. In the Google Cloud Console, go to the VM instances page.
In WinSCP, configure your connection settings.
Set the File protocol field to
SCP.In the Host Name field, specify the external IP address for the instance that you want to connect to.
In the User name field, specify the Google username that you use to access your project. For this example, the user is
example-user.
Click the Advanced drop-down list to open the advanced settings, and navigate to SSH > Authentication.
In the Private key file box, specify the path to your private key file. For this example, the key file is
my-ssh-key.ppk.
Click Ok to save the advanced settings.
Click Login to connect to your instance. If the connection is successful, the window opens your local file system on the left and the instance's file system on the right. You can navigate to different directories in these file systems and drag files to transfer them to and from your instance.
You likely do not have permission to manage most files outside of your home directory on the instance. To navigate to the home directory on the instance, enter your home directory and
usernamein the path field in WinSCP./home/username
Use the WinSCP interface to move files between your workstation and the instance.
After you copy your files to the instance, connect to your instance so that you can execute or move files with full
sudopermissions.
Transferring files to Windows instances
Transferring files through the Windows RDP client
Desktop RDP clients let you connect local devices and resources, including local drives, from your workstation to the Windows Server instance that you connect to. This makes your local workstation file system available as a remote resource while you are connected over RDP. Note that this is not available if you use the Cloud Console with the Chrome RDP extension.
For example, on a Windows Server 2016 workstation:
- Open RDP.
- Click the Local Resources tab.
- Under Local devices and resources, click More.
- Select the Drives checkbox. When you open a connection to a remote instance, the local drives that you selected are available through Windows Explorer.
For more information, see Remote Desktop clients.
What's next
- Connect to your instances to use the files that you uploaded.
