The noun 'Ablagerung' (deposit / filing) comes from the verb '(sich) ablagern' (to settle / to be deposited). It describes the result of this process: something has accumulated and settled in one place. The ending '-ung' turns the verb into a noun.
Kalk ist eine häufige Ablagerung in Wasserleitungen.
Limescale is a common deposit in water pipes.
You can distinguish the two meanings well: if the word refers to natural, chemical, or physical processes, it means the material accumulation. If it is about office work and organization, it means the filing of documents.

In the context of natural or chemical processes, you often find combinations such as 'Ablagerungen von Kalk' (limescale deposits), 'Ablagerungen in den Arterien' (deposits in the arteries), or 'Ablagerungen am Meeresboden' (deposits on the seabed).
