File name limitations

The length of file names is limited by IBM® Storage Protect API, and by Windows® Explorer when using the HSM for Windows client GUI.

The length of a file name that is migrated by the HSM for Windows client cannot exceed 256 bytes. The path length (the API high-level qualifier) cannot exceed 1024 bytes. A path and file name includes the file server name, the volume, and the directory portion of the full Uniform Naming Convention (UNC) name, for example \\FILESERVER\E:\directory\filename.ext. The Unicode representation of a character can occupy several bytes, so the maximum number of characters that a file name might contain can vary.

When using the HSM for Windows client GUI, path names can be a maximum of 254 characters only. For path names that exceed 254 characters, you must use the dsmclc.exe command from a Command Prompt window.
