Hi.
In http://dev.mysql.com/doc/refman/4.1/en/temporary-files.html says "MySQL creates all temporary files as hidden files. This ensures that the temporary files are removed if mysqld is terminated. The disadvantage of using hidden files is that you do not see a big temporary file that fills up the filesystem in which the temporary file directory is located." Is there any form of see the length of the temporary files created by MySQL? Iago.
