Document Library Services (QDLS) File System

The Document Library Services (QDLS) file system supports the folder objects. It provides access to documents and folders.

User Access

To work with the QDLS file system through the integrated file system interface, use the integrated file system commands, user displays, or ISO stream I/O functions and system APIs.

All users working with objects in QDLS must be enrolled in the system distribution directory.

Path Names

QDLS does not distinguish between uppercase and lowercase in the names containing only the alphabetic characters a to z. A search for object names achieves the same result regardless of whether characters in the names are uppercase or lowercase.

Other characters are case sensitive and are used as is.

Each component of the path name can consist of just a name, such as:


/QDLS/FLR1/DOC1

or a name plus an extension, such as:


/QDLS/FLR1/DOC1.TXT

The name in each component can be up to 8 characters long, and the extension can be up to 3 characters long. The maximum length of the path name is 82 characters.

The directory hierarchy below /QDLS/ can be 32 levels deep.

The characters in names are converted to code page 500 when the names are stored. A name may be rejected if it cannot be converted to code page 500.
