Abstract

Embodiments are described for blocking the opening of a file. Some embodiments include receiving a request to open a file. In response, a portion of the file's data is examined to determine a true file format for the file. A determination is then made as to whether the true file format of the file has been set as blocked. Based on the determination that the file format is blocked from opening, the file is prevented from being loaded into memory and from being accessed. A message is then displayed to a user indicating that the file has been blocked from opening.
