+of paths and filenames</title><shortdesc>This topic describes the structure of path and the components of
+a filename.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>A full filename consists of four components:</p>
+<ul>
+<li id="GUID-FA2E4BB1-3228-5E88-8F78-0BF7EAB14E8B"><p>the drive: a single
+letter followed by a colon.</p> </li>
+<li id="GUID-E98DCE36-6BFA-57E4-A03F-8CAB1CE587D1"><p>the path, starting with
+a backslash and ending with the final backslash in the name. The backslashes
+divide the path into components.</p> </li>
+<li id="GUID-32B125E6-9328-5AF0-AEBE-9D64CA801B61"><p>the file name: everything
+from the character following the last backslash to the character preceding
+the final dot.</p> </li>
+<li id="GUID-33B61BC0-F53C-5D50-840A-1EB1B6015227"><p>the extension, which
+consists of everything after the final dot.</p> </li>
+</ul>
+<p>In "8.3" filing systems such as FAT, the meanings of these components are
+well understood. In non-8.3 systems, the mapping is straightforward, except
+for the split of the final component of the name between filename and extension.
+The rule is that anything following the final dot of this component is the
+extension, anything preceding it is the filename. If there is no dot, or nothing
+after the final dot, the entire component is the filename, and there is no
+extension.</p>
+<p>The following table shows some sample filenames and their component parts:</p>

+<p>Note that not all parts need be present. Note also that the directory navigators <filepath>..</filepath> and <filepath>.</filepath> are
+not an intrinsic part of the file system model, and are not therefore supported
+directly in names.</p>
+<p>A directory is identified by a trailing slash: thus, <filepath>c:\wrd\</filepath> indicates
+a directory, but <filepath>c:\wrd</filepath> indicates a file with no extension.
+This mandatory requirement allows parsing to function without ambiguity, and
+also without reference to any session with the file server.</p>
+<p>The classes described here are used to handle all filename parsing requirements
+in a uniform way. Because they handle the logic consistently, and because
+this logic contains some subtle rules, you should always use them rather than
+writing your own code.</p>
