Clearmem.exe - Windows 2000 Resource Kit Utility

ClearMem is a command-line tool that forces pages out of RAM. ClearMem attempts to allocate and commit more memory then is physically available, as well as flushing the file cache. In Windows, working sets are allowed to grow until memory pressure forces them to decline. Flushing the file cache is important because some pages in the process working set are part of the file cache (for example, code loaded from a file).
