GpuHub_Sync is a free data transfer application developed by iRender. This application enables you to transfer files easily from your personal computer to the iRender servers with data storage up to Terabytes. Even when the remote server is off, you can still use this application, which saves your money considerably.

We are launching an upgrade called iRender Drive for Windows OS based on Gpuhub-sync application. iRender Drive can massively improve the customer experience: easier, faster, and more effective.

Feature: Manual vs Keep Local Path

  • The Manual function is to upload files that will be under the current directory on GpuHub_Sync.
  • The Keep Local Path function allows our system to automatically create a directory on GpuHub_Sync and Z drive that is the same as the root directory on your PC.

Let’s take an example for Keep local path function. When you upload a file from C:/Documents/Render/, our system then creates a directory on GpuHub_Sync and Z drive like this Z:/C/Documents/Render/.
