Transferring Files

Initiate and manage file transfers.

CAUTION:
Do not use the following characters in filenames:
/ \ " : ' ? > < & * |
  1. Connect to the remote host

    Start the application by launching asperascp, and double-click the connection within the Connection panel, or select it and click Connect.

    Select a connection.

    In the connections panel, the Target Directory shows either a specific path when the target directory is set, or the last-visited folder when left blank. For how to set up the target directory, see Managing Connections.

  2. Initiate the transfer

    To transfer a file to or from the remote computer, select the file to transfer and then click the upload or download arrow.

    Download a file from the remote host.
  3. Transfer files using drag-and-drop or copy-and-paste.

    You can transfer files or folders between the right and left browser panels using drag-and-drop or copy-and-paste.

    Within either the left or right browser panel, you can move files or folders using drag-and-drop or cut-and-paste, and you can copy them using copy-and-paste.

  4. Transfer files without browsing the remote host
    If you have entered the target directory for this connection (See Managing Connections), you can also transfer files without browsing the remote computer. To do so, select the files from the left panel (local), select the connection name from the right panel (remote) and click Upload to push files to the remote computer's target directory (as shown in the screenshot), or Download to pull files from it.

    Upload files without browing.

    Note: If you attempt to transfer too many files, regardless of the method, the transfer is disabled and the following warning message is displayed:
    Too many files selected. Select fewer files, or transfer the folder containing your selection instead.

    The file limit is OS dependent.

    The limit does not apply to copy-and-paste operations within the same file browser panel.

  5. Manage the transfer sessions in the Transfers panel

    Once the transfer has been successfully initiated, a progress bar will appear in the Transfers panel. If you have multiple ongoing transfers, use the Queue-forward and Queue-backward to change the selected transfer's priority. The # field indicates the transfer's order in the queue. Also the Start transfer, Stop transfer, and Delete transfer can be used to control the selected transfer session.

  6. (Optional) Make adjustments to a transfer session's target rate, minimum rate and/or policy (if allowed)

    The Details button provides additional visibility and control (if granted the proper permissions) over transfers. Select a transfer session from the Transfers panel and click Details to view details and/or adjust settings.

    Show a session's detail.

    The following items are on the Details display:

    Transfer detail.
    Item Name Description
    A Details (tab) Transfer details, including status (rate and ETA) and statistics (session size, files transferred vs. total files to be transferred, average speed, time elapsed, RTT delay and average loss in percent).
    B Files (tab) All files being transferred in this session, along with each files' size and transfer progress.
    C Transfer controls Set the FASP transfer policy and transfer rate, if allowed.
    • fixed – Attempts to transfer at the specified target rate, regardless of the actual network capacity. This policy transfers at a constant rate and finishes in a guaranteed time. This policy typically occupies most of the network's bandwidth, and is not recommended in most file transfer scenarios. In fixed mode, a maximum (target) rate value is required.
    • high – Monitors the network and adjusts the transfer rate to fully utilize the available bandwidth up to the maximum rate. When congestion occurs, a it transfers at a rate twice of a session with fair policy. In this mode, both the maximum (target) and the minimum transfer rates are required.
    • fair – Monitors the network and adjusts the transfer rate to fully utilize the available bandwidth up to the maximum rate. When other types of traffic build up and congestion occurs, it shares bandwidth fairly by transferring at an even rate. In this mode, both the maximum (target) and the minimum transfer rates are required.
    • low – Similar to fair mode, the low policy uses the available bandwidth up to the maximum rate, but is much less aggressive when sharing bandwidth with other network traffic. When congestion builds up, the transfer rate is reduced to the minimum rate until other traffic retreats.

    Important: If --policy is not set, ascp uses the server-side policy setting (fair by default).

    D Transfer Monitor The transfer graph. Note that you may use the sliders to adjust the transfer rate up or down (if allowed).

  7. Update preferences for the transfer rate and maximum number of concurrent transfers

    If you have administrator privileges, you can set the target transfer rate for all users from the Global Preferences dialog. As an individual user, you can override the global settings from My Preferences. To update these settings, go to Tools > Global Preferences or Tools > Preferences. You can also open My Preferences from the Preferences button in the upper-right corner of the application's main window; from there you can also reach the Global Preferences dialog by clicking Global Preferences.

    The preferences' Transfer window.

    The following options are available under the Transfers tab:

    Item Description
    Global Bandwidth Limits The aggregated bandwidth cap for all FASP transfers on this computer.
    Default Target Rate The initial download and upload rates for all transfers.
    Maximum Active Transfers The maximum number of concurrent upload transfers and download transfers.
