Often, it is more efficient to read a directory many entries at a time, to minimise client-server interaction. <codeph>RFs</codeph> functions and the associated <codeph>CDir</codeph> class support this requirement.</p> <p>A directory entry is represented by the <codeph>TEntry</codeph> class which may represent a directory, file or even a volume label. Attributes such as archive, hidden, system and read-only are available, as in <keyword>VFAT</keyword>.</p> </conbody></concept>
