            CompareFileExt is an Integer function used to compare the file extension in FIlename to the value in Ext.

CompareFilenameStarts calls CompareFileNames to perform the comparison, and get the return value for the function.

          <p>
            DirectoryIsWritable is a Boolean function used to determine if the specified directory name is writable in the file system. The path name in DirectoryName must already exist on the local file system. The return value is False if a directory with the specified name does not exist.
          </p>
          <p>
            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.
          </p>
          <remarks>
            Please note: DirectoryIsWritable calls InvalidateFileStateCache with the temporary file name if DeleteFileUTF8 cannot remove the file.

          <p>
            <var>ForceDirectories</var>  is a Boolean function which creates the specified directories if they do not already exist. ForceDirectories examines the value in Dir to determine if it contains a Windows device identifier or a UNC name. If a device identifer or UNC name is found, but not supported on the platform, no actions are perfomed in the function.

          <p>
            ForceDirectories raises an EInOutError exception with the message in SCannotCreateEmptyDir when Dir contains an empty string ('').

          <p>
            Each directory in the specified path is checked using DirectoryExistsUTF8.  ForceDirectories calls CreateDirUTF8 if a directory does not exist, and may exit with a return value of False if directory creation is not successful. The return value is True if all directories in the path information already exist, or are successfully created in the function.

          <p>
            OnInvalidateFileStateCache is a TInvalidateFileStateCacheEvent 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.

            InvalidateFileStateCache is a procedure used to signal the OnInvalidateFileStateCache 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:

            Resolves a symbolic link to an actual file name. It does not resolve symlinks in parent directories. If a symlink can not be resolved and if ExceptionOnError is False, the function returns an empty string (''). If ExceptionOnError is True, it raises an EFOpenError with a message, containing more details. On Windows it simply returns Filename.
