For platforms where <b>CaseInsensitiveFilenames</b> is defined, the value in IgnoreCase defaults to <b>True</b>. When IgnoreCase is <b>True</b>, the <var>UTF8CompareText</var> function is called to perform a case-insensitive comparison of the specified file names. Otherwise, the ordinal byte values in the specified file names are compared until a difference is found, or the entire file name in Filename1 has been examined.

            If either Filename1 or Filename2 are unassigned (contain <b>Nil</b>) or begin with a Null character (<b>Decimal 0</b>), the return value is set <b>0</b> (<b>zero</b>) and no additional actions are performed in the function.

            The return value is True when a file can be added, deleted, or modified in the specified path.  To get the return value, DirectoryIsWritable creates a temporary file in DirectoryName, adds content to it, and deletes the temporary file. DirectoryIsWritable calls the FileCreateUTF8, FileWrite, FileClose, and DeleteFileUTF8 routines to perform the file operations. The return value is True when FileWrite completes successfully.

            Please note: DirectoryIsWritable calls InvalidateFileStateCache with the temporary file name if DeleteFileUTF8 cannot remove the file.

            Please note: PathIsInPath ensures that a trailing path delimiter is included in the Path and Directory arguments prior to performing its comparison. On Windows, this results in a Path like 'C:' being treated as if it contains 'C:\'.

            The implementation of GetPhysicalFilename is platform- or OS-dependent. For UNIX-like environments (which support symbolic links), the <var>GetUnixPhysicalFilename</var> function is called to retrieve the file name for the symlink. For other platforms and environments, like Amiga and Windows, symbolic links are not supported and the return values always contains the value in Filename.

            <var>GetTempFileNameUTF8</var> is a <var>String</var> function used to get a temporary file name with the specified prefix located in the specified directory.

          <p>
            <var>Dir</var> contains the path on the local file system where the temporary file should be located.
          </p>
          <p>
            <var>Prefix</var> contains the prefix for the temporary file name. In other words, the temporary file name must start with this sequence of characters.
          </p>
          <p>
            GetTempFileNameUTF8 signals the OnGetTempFile event handler (when assigned) to get the value used as the temporary file name. When OnGetTempFile has not been assigned, a string is constructed using the path information in Dir and a numeric suffix to make the file name unique. For example:
          </p>
          <code>
/usr/tmp/TMP0.tmp
          </code>
          <p>
            GetTempFileNameUTF8 examines the files in the specified directory to determine if a file already exists which starts with the value in  Prefix. If a file is located in the directory, a numeric suffix (starting at 0) is appended to the base file name in Prefix to build a temporary file name which does not already exist in the directory.

            The implementation of IsUNCPath is platform- and/or OS-specific. For the Windows platform, IsUNCPath checks Path to see if it begins with the double backslash notation used for a UNC path. For example:

          <code>
  \\C:\directory\
  \\?\C:\directory\
  \\?\UNC\volume\directory\
          </code>

          <p>
            <var>ExtractUNCVolume</var> is a <var>String</var> function used to get host and volume information from a path specified using Universal Naming Convention (UNC). UNC notation is recognized using both the long and short formats defined for the naming convention.

            The return value contains information needed to access shared resources by their host and volume names, and contains one of the following formats:

          <p>
            ExtractUNCVolume calls the <var>IsUNCPath</var> function to determine if the value in <var>Path</var> starts with the UNC naming delimiters. The return value is an empty string (<b>''</b>), and no additional actions are performed in the function, when Path does not use UNC notation.
          </p>
          <p>
            ExtractUNCVolume examines the characters in Path to determine if it uses the long or the short format for UNC notation. Long format notation begins with the characters <b>'\\?\'</b>  or <b>'\\?\UNC\'</b> followed by a drive designation and optional path information such as 'c:\'. Short format notation uses a host name and a shared resource identifier such as <b>'\\mypc\nas-drive\'</b>.

          </p>
          <p>
            When FileName uses Universal Naming Convention (UNC),  the return value will contain any server and share/volume information included in the parameter. For example:

  \\?\C:\
         </code>
         <p>
           For UNIX-like environments (as well as WinCE), an initial path delimiter marks the root directory in the file system.

         <p>
           For the Amiga platform, any characters in FileName up to (but not including) the first ":" character are used as the root directory.

         <p>
           For the Windows platform, a drive designation up to and including the first path delimiter are used as the root directory. For example:

            <var>TInvalidateFileStateCacheEvent</var> is the type which specifies the event signalled for an invalid file state in the file cache. TInvalidateFileStateCacheEvent is the type used for the <var>OnInvalidateFileStateCache</var> event handler signalled in the <var>InvalidateFileStateCache</var> procedure.

        <descr>
          <p>
            <var>OnInvalidateFileStateCache</var> is a <var>TInvalidateFileStateCacheEvent</var> variable which implements the event handler signalled for a file with an invalid file state. OnInvalidateFileStateCache allows an application to respond to the event notification for a specific file. OnInvalidateFileStateCache is signalled when InvalidateFileStateCache is called by routines that perform file manipulation.

            OnInvalidateFileStateCache is significant for UNIX-like environments only, such as Linux and Amiga. OnInvalidateFileStateCache is not used in Windows environments.

          <p>
            <var>InvalidateFileStateCache</var> is a procedure used to signal the <var>OnInvalidateFileStateCache</var> event handler for the specified file name. InvalidateFileStateCache is used when an invalid file state is detected in routines which perform file manipulation, such as:

          <ul>
            <li>DeleteFileUTF8</li>
