Download – Downloading Files in Thru Web

The Download button allows you to download files and folders that are already uploaded to your Thru server.

Use the Folder Tree on the left to navigate to the files or folders you want to download.

You cannot access disabled folders; they are grayed-out to indicate they are not available for download.

A user can choose browser or Java as the download method, as well as select a default using the download drop-down menu.

Browser method is HTML 5 if it is supported by the browser.

 Google Chrome, Mozilla Firefox, and Microsoft Edge only support downloads and uploads in a Browser method. Internet Explorer 11 still supports Java, Browser, and Active X for uploads and Java/Browser for downloads.

  1. To open a comparison chart of download methods, click Select Default from the Download drop-down bar.

    The Content Panel will change to display the contents of that folder once it has been selected.
  2. Place a checkmark in front of the file you wish to download, and then click Download.
    This will open the standard folder view window where you can select where to download the files.
    If you selected more than one file or folder, all of the contents will be zipped before the download begins.
    If a large amount of files and folders is being downloaded, it may take several minutes for the download to begin while the zip package is created.

Thru Java Application Download

Thru's external download pages now offer download options via a Java web start.

For the browsers that do not support traditional Java applets any longer such as Chrome, Firefox, and Edge, please download and run .JNLP file with Thru Java Application to browse and download the files.

If your browser saves .JNLP file to a default download location, please navigate to the location in the file system and start .JNLP file.

Java is required to be installed on this machine to download the files.

Please contact your IT administrator to install and configure Java on your computer.

Please note that Chrome browser does not support Java. Use Firefox or Internet Explorer to download the files.

Internet Explorer versions 10 and 11 support traditional web application.

Considerations when Downloading Using Java

People that receive Thru download links requiring Java will need to install and configure Java on their computer and in their browser.

The recommended location to get the Java software is Java Download. Install the 32-bit version of Java if you are using 32-bit browsers.

For more information on 32-bit vs 64-bit Java, visit which Java should I use.

Google Chrome, Mozilla Firefox and Microsoft Edge no longer supports Java applets. Internet Explorer 11 still supports Java.

For more information on this subject please read this Java FAQ.
