# NMC Appendix Case Sensitivity

### Configuring case sensitivity for Windows systems with SMB/CIFS

On Windows systems that do NOT require case sensitivity for any reason, Nasuni strongly suggests configuring case sensitivity as follows:

- Specify the volume to NOT be case-sensitive. This is the default configuration of volumes.
- For the volume’s **Permissions Policy**, select **NTFS Exclusive**.

> *Note: Most Windows applications are not case-sensitive.*

If case sensitivity is REQUIRED, such as for SMB/CIFS volumes that also have NFS protocol enabled, configure case sensitivity as follows:

- Specify the volume to be case-sensitive. This is not the default configuration of volumes, and must be specified for the volume. To specify the volume to be case-sensitive, on the “**Create Volume**” page (NMC), select “**Case Sensitive**”.
- Specify the share to use “**Case-Sensitive** **Paths**”.
- For the volume’s **Permissions Policy**, select **POSIX Mixed Mode**.

On Windows systems, if some applications require case sensitivity and other applications require not being case sensitive on the same volume, configure case sensitivity as follows:

- Specify the volume to be case-sensitive. This is not the default configuration of volumes, and must be specified for the volume. To specify the volume to be case-sensitive, on the “**Create Volume**” page (NMC), select “**Case Sensitive**”.
- Specify one share on the volume to use “**Case-Sensitive Paths**”. The case-sensitive applications can use this share.
- Specify another share on the volume to NOT use “**Case-Sensitive Paths**”. The applications that are not case-sensitive can use this share.
- For the volume’s **Permissions Policy**, select **NTFS Exclusive**.
