Large folders in video and graphics production are normal, let's face it. There are 2 challenges when working with large folders with the RAP server that deserve further discussion. The first is throughput but the 2nd is what happens if it fails or spins the wheels. You don't want to redo the entire transfer and we are using the internet for the transfer which can have issues out of everyone's control.
The first way to transfer folders is to use the RAP Public links.
When the upload into a public link breaks and it is re-initiated by the remote user, it recognizes the files already uploaded, skips them and starts from the next one. That all sounds great but this presents a problem. The problem is, it will not start from the latest one since a part file or a "chunk" of the file it failed on already exists. So it will start from the next complete file and you will lose one file each time the connection is lost. You will need an additional QC step of parsing the folders to make sure
The second way to transfer folders is to use the Guest user feature
With Guest, you can share a folder with an outside user that is identified by an email address. The recipients receive an email containing an activation link for this after you enter their email into the share dialog for a folder in the RAP web browser. They can then log in using the email and password they chose during activation. Guests may even use the RAP-sync desktop app to connect to the RAP and work on shared content. Since you would share a folder with your Guest, they may also upload folders/files there.
When a Guest uploads a folder with files and gets an internet connection fail, it just stops. The uploaded content till that point will stay in the server. When going to upload the file again, they will get a pop-up stating that there are file conflicts. The Guest will just have to click on "Already existing files" and the rest of the files will upload themselves.
If they upload the folder/files through the desktop client and have the RAP server synchronized there, it will start automatically again after there is an internet connection. Using the RAP-sync client the Guest User will not have to do anything manually and there will be no data loss.
