DelphiBasics RmDir Procedure Remove a directory System unit

procedure RmDir(const DirectoryName string);

Description The RmDir procedure removes a directory from the current directory.   If the directory does not exist, an EInOutError exception is thrown.   You can avoid such an exception by preventing IO errors using the {$IOChecks Off} compiler directive. You must then check the IOResult value to see the outcome of your IO operation (rememering that use of IOResult resets the value). Related commands $IOChecks When on, an IO operation error throws an exception ChDir Change the working drive plus path for a specified drive CreateDir Create a directory GetCurrentDir Get the current directory (drive plus directory) IOResult Holds the return code of the last I/O operation MkDir Make a directory RemoveDir Remove a directory SelectDirectory Display a dialog to allow user selection of a directory SetCurrentDir Change the current directory ForceDirectories Create a new path of directories  Download this web site as a Windows program.
