/**
* Puts a file on RouterOS's file system.
*
* Puts a file on RouterOS's file system, regardless of the current menu.
* Note that this is a **VERY VERY VERY** time consuming method - it takes a
* minimum of a little over 4 seconds, most of which are in sleep. It waits
* 2 seconds after a file is first created (required to actually start
* writing to the file), and another 2 seconds after its contents is written
* (performed in order to verify success afterwards).
* Similarly for removal (when $data is NULL) - there are two seconds in
* sleep, used to verify the file was really deleted.
*
* If you want an efficient way of transferring files, use (T)FTP.
* If you want an efficient way of removing files, use
* {@link static::setMenu()} to move to the "/file" menu, and call
* {@link static::remove()} without performing verification afterwards.
*
* @param string $filename The filename to write data in.
* @param string|resource|null $data The data the file is going to have
* as a string or a seekable stream.
* Setting the value to NULL removes a file of this name.
* If a seekable stream is provided, it is sent from its current
* posistion to its end, and the pointer is seeked back to its current
* position after sending.
* Non seekable streams, as well as all other types, are casted to a
* string.
* @param bool $overwrite Whether to overwrite the file if
* it exists.
*
* @return bool TRUE on success, FALSE on failure.
