You can also enable shares to be managed centrally from the CTERA Portal. For details, see [Configuring and Managing Shares from the Portal](/v1/docs/configuring-ctera-edge-filer-shares-2-1-1-1-1#configuring-and-managing-shares-from-the-portal). **To define a network share:** 1. In the **Configuration** view, select **Shares > Shares** in the navigation pane. The **Shares** page is displayed. ![Image](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-CPU7XDQE.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A29%3A07Z&se=2026-11-11T05%3A29%3A07Z&sr=c&sp=r&sig=WeztOpBEGz6LgCyDlszkZMnDDUAN%2FPeeK158CN%2BDI40%3D) 2. Click **New Share**. 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%3A07Z&se=2026-11-11T05%3A29%3A07Z&sr=c&sp=r&sig=WeztOpBEGz6LgCyDlszkZMnDDUAN%2FPeeK158CN%2BDI40%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%3A07Z&se=2026-11-11T05%3A29%3A07Z&sr=c&sp=r&sig=WeztOpBEGz6LgCyDlszkZMnDDUAN%2FPeeK158CN%2BDI40%3D) - To create a new subfolder to select as a nested share, select the parent folder, click **New Folder**, and then assign the subfolder a name. - You can define nested shares based on subfolders within the own cloud drive, which are available to users based on the permissions defined when creating the share. If the share has NT ACL settings, these settings are applied to the nested share and to every share below this share. For example, if the administrator has a personal cloud drive named *MyGateway*, to which he migrated a full old Windows File Server with the following structure: ``` /Cloud /WIN-File-Server /Share1 /Share2 /My Files /Shared with me ``` If, before the Windows File Server migration, `\\Win-File-Server\Share1` and `\\Win-File-Server\Share2` shares were exposed in the old file server, users logged in to MyGateway can access the content of the shares: `\\MyGateway\Share1 and \\MyGateway\Share2` after they are defined: ``` Share1 = \\MyGateway\Cloud\WIN-File-Server\Share1 Share2 = \\MyGateway\Cloud\WIN-File-Server\Share2 ``` 4. Click **Next** and then assign the network share a name. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-1AC2CI92.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A29%3A07Z&se=2026-11-11T05%3A29%3A07Z&sr=c&sp=r&sig=WeztOpBEGz6LgCyDlszkZMnDDUAN%2FPeeK158CN%2BDI40%3D) 5. Click **Next** and choose through which sharing protocols to expose this share. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-JYISTFMZ.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A29%3A07Z&se=2026-11-11T05%3A29%3A07Z&sr=c&sp=r&sig=WeztOpBEGz6LgCyDlszkZMnDDUAN%2FPeeK158CN%2BDI40%3D) **Windows File Sharing** is checked by default and cannot be deselected. From the drop-down, select one of these access levels for the share: For more information, see [Configuring Windows File Sharing](/v1/docs/network-sharing-protocols-7-1-1#configuring-windows-file-sharing). **Client Side Caching** – Server files are designated for off-line work so that a copy of the files is cached on the client computer and can be accessed when the client is off line in exactly the same way as if they were stored on the Windows file server. - **Windows ACL Emulation Mode** – The share will be a Windows ACL emulation mode share. 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. Windows ACL Emulation Mode also allows you to block users from writing specific file types into the CTERA Edge Filer share or gaining control of the content located on it. 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-5-1-1-1-1#copying-files-from-an-external-file-server-to-the-ctera-edge-filer). - **Only Authenticated Users** – Users will be required to authenticate using their CTERA Edge Filer user name and password, in order to access the network share. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-J99K6PPB.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A29%3A07Z&se=2026-11-11T05%3A29%3A07Z&sr=c&sp=r&sig=WeztOpBEGz6LgCyDlszkZMnDDUAN%2FPeeK158CN%2BDI40%3D) - **Automatic caching for documents** – A copy of the files is cached automatically. - **Disabled** – The client computer cannot cache files locally and the updated copy must be retrieved from the file server. - **Manual caching for documents** – Users must cache files manually. 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%3A07Z&se=2026-11-11T05%3A29%3A07Z&sr=c&sp=r&sig=WeztOpBEGz6LgCyDlszkZMnDDUAN%2FPeeK158CN%2BDI40%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%3A07Z&se=2026-11-11T05%3A29%3A07Z&sr=c&sp=r&sig=WeztOpBEGz6LgCyDlszkZMnDDUAN%2FPeeK158CN%2BDI40%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. Either, click **New** to configure each client to which you want to grant access. A row is displayed in the table: Or, Click **Remove** and then select the client's IP address to remove the client from the list. **Note** Concurrent access to files using both NFS and SMB is supported. However, writing files concurrently with both protocols introduces potential risks of data incoherence. For details, see [Concurrent Access to Files Using NFS and SMB Protocols](/v1/docs/network-sharing-protocols-7-1-1#concurrent-access-to-files-using-nfs-and-smb-protocols) 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**. 11. Click **Next** and set which users can access this network share. ![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%3A07Z&se=2026-11-11T05%3A29%3A07Z&sr=c&sp=r&sig=WeztOpBEGz6LgCyDlszkZMnDDUAN%2FPeeK158CN%2BDI40%3D) **Note** 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. 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 who should have access to the network share. 4. For each user and user group, click in the **Permission** field, and then select the access level from the drop-down list. 12. Click **Next** and then **Finish** to complete the wizard. ## Copying Files From an External File Server to the CTERA Edge Filer **Notes** To copy a whole file server (such as a Windows or NetApp file server) by migrating it to the CTERA Edge Filer requires in-depth planning and should be done in conjunction with CTERA support. To copy individual shares from a file server, use the procedure described in [Migrating Shares](/v1/docs/migrating-shares-3-1-1-1-1). You can also perform a delta migration when you previously set up the migration, as described in [Completing a Migration and Performing a Delta Migration](/v1/docs/migrating-shares-3-1-1-1-1#completing-a-migration-and-performing-a-delta-migration). ## Modifying Shares Select the share and click **Edit Share**. Proceed as for defining a new network share. ## Removing Shares Select the share, click **Remove Share** and then **Yes** to confirm. This removes the share from the volume or folder it was defined on.
