With the file transfer feature, you can transfer files between the client system and a remote desktop or published application.
A Horizon administrator can configure the ability to allow, disallow, or allow in one direction only, the transfer of files by modifying the Configure file transfer group policy setting for VMware Blast. This group policy setting has the following values.
- If the Disabled both upload and download value is selected, the File Transfer button is disabled.
- If the Enabled file upload only value is selected (the default setting), only the Upload tab appears in the Transfer Files window.
- If the Enabled file download only value is selected, only the Download tab appears in the Transfer Files window.
If the Configure clipboard redirection group policy setting is disabled from the server to the client, file download is also disabled.
For more information about these group policy settings, see the Configuring Remote Desktop Features in Horizon document.
This feature has the following limitations.
- You can download files up to 500 MB and upload files up to 2 GB.
- For 32-bit Internet Explorer 11, downloading a file larger than 300 MB might not work. To resolve the issue, run Internet Explorer 11 in 64-bit mode.
- You cannot download or upload folders or files that have a size of zero.
- Safari on iOS, and Safari 8, do not support upload or download. Safari 9 and later do not support download.
- If a file transfer is in progress in a remote session and you open a connection to a second remote session, and if a security warning appears, if you ignore the warning and continue to connect to the second remote session the file transfer in the first session aborts.
- If you upload a file with Internet Explorer 11, or with Chrome on a Chromebook, if you drag and drop folders, files of zero size, or files that are larger than 2 GB, you receive an error message as expected. After you dismiss the error message, you can no longer drag and drop files that can be transferred.
- You cannot use this feature with Linux remote desktops or Android devices.
