CIFS case sensitivity

The Windows operating system is case preserving but not case sensitive. The HCP CIFS implementation, by default, is both case preserving and case sensitive. One result of this discrepancy is that Windows applications that don’t observe differences in case may not be able to access objects by name.

For example, suppose a Windows application adds a file named File.txt to the namespace by using the CIFS protocol. CIFS preserves case, so the namespace then contains an object named File.txt. Now suppose the application tries to retrieve that object using the name file.txt. CIFS is case sensitive, so it passes the request to HCP with only the name file.txt. It doesn’t include any case variations on the name, such as File.TXT or FILE.txt. As a result, HCP cannot find the object.

You can ask your tenant administrator to make the CIFS implementation case insensitive. However, this change has two consequences that affect object reads:

  • It slows performance.
  • If the namespace contains multiple objects with names that differ only in case, HCP may return the wrong object.
