If theDestinationPath ); destination file does not exist, a new file is created with the specified name in the specified pathCreate( string Path ) Used to create a file with the specified name in the specified pathDelete( string Path ) Used to delete a file from a specified pathExists( string Path ) Used to verify whether a file with the specified name exists in the specified path. It returns a Boolean valueMove( string Used to move the specified file from theSourcePath, string source location to the destination locationDestinationPath )Directorymethods Methods DescriptionCreateDirectory (String Creates all the directories in the specifiedPath) pathDelete( string Path ) Deletes an empty directory from a specified pathExists( string Path ) Checks whether the given path refers to an existing directory on diskMove( string Used to move the specified file from theSourceFilePath, string source location to the destination locationDestinationFilePath )GetCurrentDirectory() Returns the current working directoryGetDirectories ( string Gets the names of subdirectoriesPath)Ge ...
