Contact your site support group.

There are various ways to do this, and many sites have developed their own procedures and programs as well -- if so, you should use the site standard. If your site does not have such a standard program, you can write a program (if you are allowed at your site to use the SP API calls) that can open / close files. Or, you may (if you are allowed at your site) to write console commands in jobs that open / close files.
