Oftentimes, you may need to share data on an HPC resource with others who aren’t on it. Globus allows users to share files with these people with guest collections, which are mini-collections that you as a user can create and add others to as you need.

Creating a Guest Collection to Share Data

Guest collections created on CCS resources now allow you to grant write permissions to those with whom you share your files (except for public). This means that they can write over/delete already existing files like you would be able to, albeit to only the files in this guest collection that you have shared with them. It will be YOUR responsibility to ensure that those you share with have appropriate access to the files you share with Globus. If you have any questions regarding permissions or sharing files in Globus, please contact the CCS Helpdesk.

  1. On http://globus.org, search for the collection from which you wish to share files.

  2. To the left/right of the file display, there should be a “Share” option you can click.

  3. This will take you to a screen on the collection that shows all associated guest collections. Click “Add Guest Collection“at the top-right of the screen.

  4. Name the collection on the following screen and click “Create Collection“.

    1. You may optionally add information to the other fields or require transfers from the collection to be encrypted.

  5. Once created, you’ll be taken to a permissions screen. By default, only you will have access to the new collection. Click the “Add Permissions—Share With“ button at the top-right of the screen.

  6. On the following screen, you can give permissions to one of the following types of users:

    1. A specific Globus user, who you can look up by name.

    2. A Globus group

    3. All Globus users

    4. Public (anyone, even those without a Globus account)

  7. After you grant permissions, you will be prompted to add another one. Click “Add another Permission“ if you have more to add to your collection, and you’ll return to the previous screen. Click “ Done” otherwise.

Sharing and Updating Permissions on your Guest Collection

Once you have created a guest collection, Globus users can search for the guest collection in the File Manager like any other collection in Globus.
You can share a URL by clicking “Get Link“ on the sidebar in File Manager. You can also share a URL to a specific file if you select it.


You can access the details of the guest collection, including the page to add/remove permissions, by searching for the collection in File Manager and clicking on the “triple dots” icon to the right of the collection.

That same icon is present when you have opened the guest collection in File Manager.
