    Article Summary

    FileZilla Pro is a File Transfer Protocol (FTP) tool that supports Backblaze B2 Cloud Storage. Using FileZilla Pro, you can quickly browse and transfer data into and out of your Backblaze B2 bucket.

    This article provides the steps to configure and optimize FileZilla Pro on a Windows computer.

    Enable Backblaze B2

    Before you begin: You must have a Backblaze B2 Cloud Storage account. You can sign up here. If you already have a Backblaze account and the left navigation menu contains a B2 Cloud Storage section, your account is already enabled for Backblaze B2.

    1. Sign in to your Backblaze account.
    2. In the left navigation menu under Account, click My Settings.
    3. Under Enabled Products, select the checkbox to enable B2 Cloud Storage.
    4. Review the Terms and Conditions, and click OK to accept them. 

    Create an Application Key

    Application keys control access to your Backblaze B2 Cloud Storage account and the buckets that are contained in your account.

    1. Sign in to your Backblaze account.
    2. In the left navigation menu under Account, click Application Keys.
    3. Click Add a New Application Key, and enter an app key name.
      You cannot search an app key by this name; therefore, app key names are not required to be globally unique. 
    4. In the Allow Access to Bucket(s) dropdown menu, select All or a specific bucket.
    5. Select your access type (for example, Read and Write).
    6. Select the optional Allow List All Bucket Names checkbox (required for the Backblaze B2 S3-compatible API List Buckets operation).
    7. Click Create New Key, and note the resulting keyID and applicationKey values.
    Note
    When you create a new app key, the response contains the actual key string, for example N2Zug0evLcHDlh_L0Z0AJhiGGdY. You can always find the keyID on this page, but for security, the applicationKey appears only once. Make sure you copy and securely save this value elsewhere.

    Set Up FileZilla Pro

    Before you begin: You must download and install FileZilla Pro on your computer.

    1. Sign in to your FileZilla Pro account.
    2. In the menu bar, select File and select Site Manager.
    3. Click New Site.
    4. Change the name from New Site to a more descriptive name for the connection, for example, Backblaze B2.
    5. Configure the settings on the General tab.
      1. Select Backblaze B2 in the Protocol field.
      2. Enter api.backblazeb2.com in the Host field.
      3. Enter 443 in the Port field.
      4. Enter your Backblaze B2 key ID in the Application Key ID field.
      5. Enter your Backblaze B2 application key in the Application Key field.
    6. Click OK.

    Create a New Bucket

    You can create a new Backblaze B2 bucket in FileZilla Pro. To create a bucket using the Backblaze web UI, click here.

    1. In the menu bar, select File and select Site Manager.
    2. Double-click Backblaze B2 to connect to your account.
      Your local files are displayed on the left side of the screen, and a list of the buckets in your Backblaze B2 account are displayed on the right side of the screen.
    3. Right-click the right side of the screen, and select Create directory.
    4. Enter a globally unique name for your bucket.

    Transfer Files

    After you set up FileZilla Pro, you must connect FileZilla Pro to your Backblaze B2 account.

    FileZilla Pro displays your local files on the left side of the screen and a list of the buckets in your Backblaze B2 account on the right side of the screen. You can use either of the following options to transfer your files. 

    1. Drag and drop files from the left side of the screen to the right side of the screen.
    2. Select one or more files, right-click the files, and click Upload.

    Optimize Reliability and Speed

    When transferring large files, a disruption in your Internet connection can result in your file failing to transfer. FileZilla Pro has optional settings that you can use to improve the reliability of your file transfers. Increasing the file timeout and number of connection retries can help prevent file transfer failure due to network disruptions.

    By default, FileZilla Pro only allows you to transfer one file at a time. But if you have a fast Internet connection, you may want to transfer multiple files at the same time. You can increase the number of concurrent file transfers up to a maximum of 10 files.

    Improve Connection Performance

    1. In the menu bar, select Edit and select Settings.
    2. In the left side panel, click Connection.
    3. Enter 300 in the Timeout in seconds field.
    4. Enter 15 in the Maximum number of retries field.

    Transfer Multiple Files 

    You can transfer multiple files at the same time if you have a fast Internet connection.

    1. In the menu bar, select Edit and select Settings.
    2. In the left side panel, click Transfers.
    3. Enter the number of file transfers that you want to run concurrently in the Maximum simultaneous transfers field.
    4. Enter 0 in the Limit for concurrent downloads field.
    5. Enter 0 in the Limit for concurrent uploads field.
