About housekeeping

In computer programming, housekeeping can refer to either a standard entry or exit routine appended to a user-written block of code at its entry and exit or to any other automated or manual software process whereby a computer is cleaned up after usage. This might include such activities as removing or archiving logs that the system has made as a result of the users activities, or deletion of temporary files which may otherwise simply take up space. Housekeeping can be described as a necessary chore, required to perform a particular computer's normal activity but not necessarily part of the algorithm. For cleaning up computer disk storage, utility software usually exists for this purpose such as data compression software - to "shrink" files and release disk space and defragmentation programs - to improve disk performance.
