Original Abstract Submitted
An object is to provide a technique to make it difficult to restore data remaining in a memory by a simple method. The printing apparatus includes: a reception unit configured to receive a file transmitted from an external device; a volatile memory storing data included in the file in a case where the external device is a predetermined server; and an overwriting unit configured to rewrite the data with dummy data, which is stored in a sector to a limit of the capacity in the volatile memory, in a case where the sector of the volatile memory storing the data is invalid.
