Abstract
A clean-up system recaptures part of the memory or secondary storage space on a client device, such as a handheld personal computer. E-mail messages are organized in a hierarchy of folders within a database. Each folder may or may not contain e-mail messages. Preferably, a user downloads e-mail messages from a server to the client device. Upon placing e-mail messages into a folder, a flag set module marks the folder with a cleanup flag. The user marks any folders, messages from which he wishes to use upon disconnect from the server, for off-line use. The clean-up system parses the folder hierarchy, beginning with the first folder in the hierarchy. A clean-up module determines if the clean-up flag is set for the first folder. If the cleanup flag is set for the first folder, an off-line module determines if the folder is marked for off-line use. If the folder is marked for off-line use, the messages contained within the folder are retained for later use. If the folder is not marked for off-line use, a delete module deletes the messages contained within the folder, recapturing part of the memory or secondary storage space on the client device. This routine is repeated for each folder …
