从存储介质中删除文件有两个目的：它收回存储资源，并确保文件中包含的任何敏感信息变得无法访问。出于后一个目的进行操作时，至关重要的是将文件安全删除，这意味着其内容在删除后不会持续在存储介质上。安全删除是从存储介质中删除数据的行为，以便随后从存储介质无法恢复数据。删除数据与它变得不可恢复之间的时间称为删除延迟。
Deleting a file from a storage medium serves two purposes: it reclaims storage resources and ensures that any sensitive information contained in the file becomes inaccessible. When done for the latter purpose, it is critical that the file is securely deleted, meaning that its content does not persist on the storage medium after deletion. Secure deletion is the act of deleting data from a storage medium such that the data is afterwards irrecoverable from the storage medium. The time between deleting data and it becoming irrecoverable is called the deletion latency.
