FTS3 controls transfers between an active and a passive endpoint at the involved centres. FTS3 controls transfers between an active and a passive endpoint at the involved centres.
The main advantage of using FTS3 compared to commonly used FTP or SCP based transfers is that no active involvement by the user is needed after commissioning the transfer. Hence, users can schedule the transfer, e.g. overnight, and have the data ready for use later.

#### How do I use HTS?
In order to use HTS, you need to:
* Know the URLs of the endpoints you want to use (available from the centre if they are participating in HTS),
* access [WebFTS](https://webfts.fedcloud-tf.fedcloud.eu/) in your browser,
* log in via Helmholtz AAI (upper left corner),
* click on 'Submit a transfer',
* enter the URLs of the endpoints between you want to transfer data,
* select the data you want to transfer on one endpoint,
* click on one of the arrows between the directory views according to the direction of the transfer.
After submitting, you should see a banner stating that your transfer has been submitted successfully. You can check the transfer status by clicking on 'My jobs'.

At the time of writing, HIFIS offers a passive endpoint solution in form of an Apache webserver for installation at a centre. At the time of writing, HIFIS offers a passive endpoint solution in form of an Apache webserver for installation at a centre.
