Configuring file sync and share requires that the CTERA Portal is configured before the CTERA Edge Filer. For details, see [Configuring the CTERA Portal as a Precondition to Setting Up the CTERA Edge Filer](/v1/docs/configuring-the-ctera-portal-as-a-precondition-to-setting-up-the-ctera-edge-filer-4-1-1-1). **Note** When using CTERA Migrate to migrate shares from a file system to a CTERA Edge Filer, the shares are setup in the CTERA Portal as part of the migration process. **To configure CTERA Edge Filer shares:** 1. Verify that the CTERA Edge Filer is connected to Active Directory. 1. Log in to the CTERA Edge Filer as an administrator. 2. In the **Configuration** view, select **Shares > Windows File Sharing** in the navigation pane. The **Windows File Sharing** page is displayed. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-51ONA7SY.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A29%3A15Z&se=2026-11-11T05%3A29%3A15Z&sr=c&sp=r&sig=ZNd4RZ29HiI9toP4bAGv0curn2lSdvDHvx1gLva1TPA%3D) 3. In the **Domain/Workgroup** section, verify that the **Operation Mode** is **Domain** and that the **Status** is **OK**. Otherwise, click **Connect to Domain/Workgroup** to connect to an Active Directory domain, as described in [Defining Users From an Active Directory Domain, Tree or Forest](/v1/docs/adding-and-editing-users-6-1-1-1#defining-users-from-an-active-directory-domain-tree-or-forest). 2. In the **Configuration** view, select **Cloud Drive > Cloud Drive** in the navigation pane. The **Cloud Drive** page is displayed. ![Image](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-AJ7C9QEW.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A29%3A15Z&se=2026-11-11T05%3A29%3A15Z&sr=c&sp=r&sig=ZNd4RZ29HiI9toP4bAGv0curn2lSdvDHvx1gLva1TPA%3D) 3. Click **Settings**. The **Cloud Drive Settings** window is displayed. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-76LJ2XC3.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A29%3A15Z&se=2026-11-11T05%3A29%3A15Z&sr=c&sp=r&sig=ZNd4RZ29HiI9toP4bAGv0curn2lSdvDHvx1gLva1TPA%3D) 4. Make sure the **Operation Mode** is **Caching Gateway**. 5. Click **Save**. To work with Windows ACL, the sharing protocol must be **Windows ACL Emulation Mode**. Windows ACL enabled folders on the CTERA Portal cannot be synced unless the cloud share is defined as **Windows ACL Emulation Mode**. **To configure CTERA Edge Filer shares with ACL support:** **Note** NT ACLs cannot be applied to root cloud folders. Therefore, do not share root cloud drive folders. CTERA recommends appending `-CF` as an identifier to root cloud folders helping to prevent it from being shared. 1. In the **Configuration** view, select **Shares > Shares** in the navigation pane. 2. Click the **cloud** share that was automatically created when it synced to the CTERA Portal. The **Select a Folder to Share** window is displayed. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-Z20DEVOI.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A29%3A15Z&se=2026-11-11T05%3A29%3A15Z&sr=c&sp=r&sig=ZNd4RZ29HiI9toP4bAGv0curn2lSdvDHvx1gLva1TPA%3D) 3. Drill-down to display the volumes and folders on the edge filer and select the volume, folder, or subfolder on which you want to define the share. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-JLPHMXD5.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A29%3A15Z&se=2026-11-11T05%3A29%3A15Z&sr=c&sp=r&sig=ZNd4RZ29HiI9toP4bAGv0curn2lSdvDHvx1gLva1TPA%3D) 4. Select a subfolder below the cloud drive folder to share and click **Next**. The **Specify the Network Share Name** window is displayed. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-J5UX8Y63.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A29%3A15Z&se=2026-11-11T05%3A29%3A15Z&sr=c&sp=r&sig=ZNd4RZ29HiI9toP4bAGv0curn2lSdvDHvx1gLva1TPA%3D) **Note** Root cloud drive folders with ACL support cannot be shared directly as an SMB share. The SMB share must be a folder under the root cloud drive folder. 5. Optionally, change the **Network Share Name** and click **Next**. The **Sharing Protocols** window is displayed. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-FQKUU3DM.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A29%3A15Z&se=2026-11-11T05%3A29%3A15Z&sr=c&sp=r&sig=ZNd4RZ29HiI9toP4bAGv0curn2lSdvDHvx1gLva1TPA%3D) Users access the shared files and folders through standard Windows client computers; for example, using Windows File Explorer through the SMB access provided by the CTERA Edge Filer. **Note** **Windows File Sharing** is checked by default and cannot be deselected. From the drop-down, select **Windows ACL Emulation Mode**. The share will be a Windows ACL emulation mode share. To copy the files with their ACLs to the CTERA Edge Filer, see [Copying Files From an External File Server to the CTERA Edge Filer](/v1/docs/managing-network-shares-5-1-1-1#copying-files-from-an-external-file-server-to-the-ctera-edge-filer). 6. Specify how you want to share the files. **FTP** – Users will be able to access and download files on this share from the FTP site. To configure the FTP server, go to **Shares > FTP Server**. 7. Click **Next**. The **Block File Types** window is displayed. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-KNVSH6YN.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A29%3A15Z&se=2026-11-11T05%3A29%3A15Z&sr=c&sp=r&sig=ZNd4RZ29HiI9toP4bAGv0curn2lSdvDHvx1gLva1TPA%3D) 8. Check **Enable Blocking File Extensions** to block file extensions. Enter the file extensions per user and group: 1. In the Local Users drop-down list, select one of the following: **Local Users** – Search the users defined locally on the CTERA Edge Filer. **Domain *domain* Users** – Search the users belonging to the domain called *domain*. **Local Groups** – Search the user groups defined locally on the CTERA Edge Filer. **Domain *domain* Groups** – Search the user groups belonging to the domain called *domain*. 2. In the **Quick Search** field, type a string that is displayed anywhere within the name of the user or user group you want to add, or click **...** to list the users. A list of users or user groups matching the search string is displayed. 3. Select the user or user group in the table. The user or user group is added to the list of users and user groups for who, you want to block some file extensions. 4. For each user and user group, click in the **Extensions** field, and then specify the extensions to block, with each extension separated by a comma (,). List only the letters of each file extension. For example, to block EXE files, list the `exe` file extension; to block PDF files, list the `pdf` file extension. To block both EXE and PDF files, list them as `exe,pdf`. Blocked extensions are not case sensitive. Wildcards (for example, `*.exe`) are not supported. 9. Click **Next**. The **NFS (UNIX File Sharing)** window is displayed. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-SJX5V5KG.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A29%3A15Z&se=2026-11-11T05%3A29%3A15Z&sr=c&sp=r&sig=ZNd4RZ29HiI9toP4bAGv0curn2lSdvDHvx1gLva1TPA%3D) **Note** The NFS mount path for the share, when NFS access is enabled, is displayed. 10. Check the **Enable NFS Access** option to enable NFS clients to access the share. Both NFS versions 3 and 4 protocols are supported, depending on the protocol used by the client. 11. Click **New** to configure each client to which you want to grant access. A row is displayed in the table: **Note** All shares on all edge filers for the same portal cloud folder **must** be NFS enabled. 1. Enter the client's IP address in the **Host** field and the netmask in the **Netmask** field. 2. Select the permitted level of access to the network share via NFS. Options are **None**, **Read Only**, or **Read/Write**. 12. Click **Next**. The **Configure Permissions** window is displayed. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-MO9FYHN0.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A29%3A15Z&se=2026-11-11T05%3A29%3A15Z&sr=c&sp=r&sig=ZNd4RZ29HiI9toP4bAGv0curn2lSdvDHvx1gLva1TPA%3D) 13. Specify the share permissions. **Note** These permissions are not inherited from the CTERA Portal. Read only and Read/Write permissions follow the Samba convention of using the less strict permission. Therefore, specific permissions for a user or group do not override the permission in the **Permission** field. For example, a user with read only permission can access a share with read/write permission if the user is in the group, like the **Everyone** group, that has a read/write permission. **Workaround**: Make sure all users that have the read only permission are in a group that only has a read only permission and not in a group that has read/write permission. 14. Click **Next** and then click **Finish**. 15. Repeat for all the shares you want to work with Windows ACLs. The shares are displayed in the **Shares** page. Users can access their files directly with SMB by mapping the share name in the file manager. Both Windows File Explorer and macOS Finder report that the total space and available free space for the mapped drive is a very high number to simulate the caching ability of infinite storage. **Note** Share names cannot include two spaces together in the name. You can achieve the nested sharing without imposing Windows ACLs. **To configure CTERA Edge Filer shares without ACL support:** - When configuring the CTERA Portal, on each cloud drive folder that you do not want ACL support, uncheck **Enable Windows ACLs**. - When configuring the CTERA Edge Filer, set **Only Authenticated Users** and not **Windows ACL Emulation Mode**, which is set by default in the **Sharing Protocols** window. ![Image](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-6POOUDWL.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A29%3A15Z&se=2026-11-11T05%3A29%3A15Z&sr=c&sp=r&sig=ZNd4RZ29HiI9toP4bAGv0curn2lSdvDHvx1gLva1TPA%3D)
