Digital hoarding  Digital hoarding (also known as e-hoarding, datahording or cyberhoarding) is excessive acquisition and reluctance to delete electronic material no longer valuable to the user. The behavior includes the mass storage of digital artifacts and the retention of unnecessary or irrelevant electronic data. The term is increasingly common in pop culture, used to describe the habitual characteristics of compulsive hoarding, but in cyberspace. As with physical space in which excess items are described as "clutter" or "junk", excess digital media is often referred to as "digital clutter". Because of its non-physical nature, the condition does not show itself through physical clutter, meaning that it does not get classified as hoarding disorder. As a consequence, it is often not recognized as a medical condition. However, because digitization has greatly facilitated acquiring and storing large quanta of information (in terms of time and costs involved), digital hoarding tends to be a slow-moving progression, because even those affected by it do not display typical behaviors associated with hoarding. Digital clutter is the term often used to describe the resulting (digital) artifacts of digital hoarding, but it should not be understood as exclusively the result of hoarding. Digital clutter can be created as a side-effect of high occurrences of another user activity, such as the computer desktop icons created through frequent installation of applications. In such a case the clutter does not reflect the user's intent to hoard. Housekeeping is the term often used to refer to the activity by which digital clutter moves out of the 'clutter' designation, either by being thrown away, or by the recognition of its importance, thus no longer making it part of the 'clutter'. Digital hoarding occurs in any electronic spaces where information is stored. These are common areas where digital clutter may exist:  A cluttered email inbox arises when a user does not have a system for archiving some messages and deleting others that are no longer wanted. Electronic documents can become clutter if a user does not delete extraneous files, or if the files are poorly organized (e.g. inconsistent folder structure, empty folders). Some social media platforms also provide opportunity for digital hoarding. On the social networking site Facebook, for example, one can accumulate a vast number of “friends” that may merely be acquaintances or lapsed contacts or even complete strangers. Groups and Pages can also contribute to clutter when users join and like new ones, respectively, without leaving or unfollowing those in which they are no longer interested.
