By default, the folder group is assigned a name based on the device's name. You can add new folder groups manually. **To add a folder group:** 1. Select **Folders > Folder Groups** in the navigation pane. The **Folder Groups** page opens, displaying all folder groups. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-MJQXFXLB.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A23%3A39Z&se=2026-11-11T05%3A23%3A39Z&sr=c&sp=r&sig=aFsu8kMp5r%2BBEmheNlkJhmh81t3LbOw2%2BsOrNH%2Bwtw8%3D) 2. Click **New Folder Group**. The **New Folder Group** window is displayed. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-Z55MX5KF.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A23%3A39Z&se=2026-11-11T05%3A23%3A39Z&sr=c&sp=r&sig=aFsu8kMp5r%2BBEmheNlkJhmh81t3LbOw2%2BsOrNH%2Bwtw8%3D) 3. Complete the fields in the **General** option. **Name** – A name for the folder group. **Owner** – An owner for the folder group. When editing a folder group, you can click on the owner's name to open the User Account Manager and manage the owner's user account. For information on managing user accounts, see [Managing Users](/v1/docs/managing-users-5). **Deduplication Method** – Whether to use the average block size or a fixed block size for deduplication. The options in the window change depending on what is selected to either **Fixed Block Size** or **Average Block Size**. Use **Fixed Block Size** if many of the folder groups that large files where deduplication is not common, such as media files, or if the global administrator defined direct mode for the storage node. **Fixed Block Size/Average Block Size** – The fixed block size used by the folder group or the average block size used by the folder group. The default value when set to **Fixed Block Size** is 4MB and 512KB when set to **Average Block Size**. CTERA Portal deduplication splits each stored file into blocks. Increasing the **Fixed Block Size** or **Average Block Size** causes the files to be split into larger chunks before storage, and results in increased read/write throughput at the cost of a reduced deduplication ratio. Increased block size is useful for workloads that require high performance, as well as for those that do not gain greatly from deduplication. For example, where the stored files consist mostly of videos, images, and music files that are not frequently modified. Decreasing the average block size can result in better deduplication, since the portal can better identify finer-grained duplicate data. If the global administrator defined direct mode for the storage node, CTERA recommends keeping the default 4MB fixed block size. **Average Map File Size** – The average map file size used by new folder groups. CTERA Portal uses file maps to keep track of the blocks each file is made of. The **Average Map File Size** represents the maximum size of file that will be represented using a single file map object. For example, if the average map file size is set to 100MB, files of up to approximately 100MB will have one file map, files of up to approximately 200MB will have two file maps, and so on. Reducing the average map file size causes more file maps to be created per file. This may result in smoother streaming of files; however, it will also result in some extra overhead for creating, indexing, and fetching the additional file maps. **Storage Class** – The storage class where content of the folder group is written. **Note** A storage class is a group of one or more storage nodes, defined by the CTERA Portal global administrator, where data is written and saved. When a storage class is defined, you can specify to which group of storage nodes content from the edge filer is written to. You must specify a storage class that is valid for the virtual portal and you need to check with the global administrator for the list of valid storage classes that you can chose from the list. After the folder group is created, the storage class cannot be changed. **Passphrase protected** – The folder is passphrase protected. **Note** Protecting a folder group is only relevant for backup folders. **Notes** You can only define a passphrase when creating the folder group and when **Passphrase protected** is checked. After the folder group is created with a passphrase, you can change the passphrase, described in [Changing a Folder Group Passphrase](/v1/docs/changing-a-folder-group-passphrase-5). The passphrase is applied to every new folder in the folder group. After creating the folder group the **Name** can be changed and the **state** can be changed from online to offline or offline to online. - **Your New Passphrase** and **Confirm New Passphrase** – A new passphrase. - **Passphrase Strength** – Displays the passphrase's strength. 4. Click **Save**. ## Editing a Folder Group You can edit folder group properties. **To edit a folder group:** 1. Select **Folders > Folder Groups** in the navigation pane. The **Folder Groups** page opens, displaying all folder groups. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-MJQXFXLB.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A23%3A39Z&se=2026-11-11T05%3A23%3A39Z&sr=c&sp=r&sig=aFsu8kMp5r%2BBEmheNlkJhmh81t3LbOw2%2BsOrNH%2Bwtw8%3D) 2.

For information on managing user accounts, see [Managing Users](/v1/docs/managing-users-5). **Change Passphrase** – When a passphrase is defined for the group, you can click the link to change a passphrase, as described in [Changing a Folder Group Passphrase](/v1/docs/changing-a-folder-group-passphrase-5). - **Online**– The folder group is online. Click **Make Offline** to change the state to offline. - **Offline** – The folder group is offline. Click **Make Online** to change the state to online.
