File types

The following file types are currently supported in the DMS file system:

• SAM files with fixed or variable record length.

• ISAM files with fixed or variable record length.

• PAM files.

The UFS file system does not distinguish between file types. In particular, there are no defined file types with record/block structure. Only the content of a file and the processing programs determine what can happen to it or what it is intended for (see section "Access methods").

As with java.io.File, only regular files and directories are supported under JRIO.
