 ====== Sharing files with other users ======
-Sometimes you need to share files with some colleagues or your research group.
+Sometimes, you may need to share files with colleagues or members of your research group.
-We provide two types of shared folders :
+We offer two types of shared folders:
-  * in "home" (''/home/share/'') - to share scripts and shared libraries for a common project
-  * in "scratch" (''/srv/beegfs/scratch/shares/'') - to share datasets for instance
-If you need one, please fill the form on DW: https://dw.unige.ch/openentry.html?tid=hpc
+  * **In the "home" directory** (`/home/share/`): Ideal for sharing scripts and common libraries related to a project.
+  * **In the "scratch" directory** (`/srv/beegfs/scratch/shares/`): Suitable for sharing larger files, such as datasets.
-If you are an Outisder user and you don't have access to DW,  please request to your PI to fill the form.
+To request a shared folder, please fill out the form at [[https://dw.unige.ch/openentry.html?tid=hpc|DW]]. As part of the request, you'll be asked if you already have a *group* you’d like to use. If this isn't the case, you'll need to create one ([[https://dw.unige.ch/openentry.html?tid=adaccess|link]] on the form)
+A **group** is a collection of users used to manage shared access to resources. These groups are defined and stored in the **Active Directory** and allow us to control who can access specific folders.
+If you need more details about groups, please contact your **CI** (*correspondant informatique*).
+If you are an *Outsider* user and do not have access to DW, please ask your **PI** to submit the request on your behalf.
 <note important>
 You are not allowed to change the permission of your ''$HOME/$SCRATCH'' folder on the clusters. Even if you did, our automation scripts will break what you did.

+===== EOS =====
+You can mount root filesystems using EOS.

 ====== Robinhood ======
 Robinhood Policy Engine is a versatile tool to manage contents of large file systems. It daily scans the scratch beegfs filesystems. It makes it possible to schedule mass action on filesystem entries by defining attribute-based policies.
