1. A method of blocking the opening of a file, the method comprising:
- configuring at least one processor to perform the steps of;
receiving a request to open a file;
examining a portion of the file'"'"'s data to determine a true file format for the file;
determining whether the true file format is of a format that is blocked from being opened, wherein an open block policy is stored in a registry and a registry key is used to set the open block policy for a file to prevent an application from opening a file of a specific file type and associated format;
based on the determining, blocking the opening of the file by preventing the loading of the file into memory and preventing access to the file; and
displaying a message indicating that the file has been blocked from opening.

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.

11. A computer readable storage medium encoding instructions, wherein the computer readable storage media does not consist of a propagated data signal, wherein when the encoded instructions are executed by a processor, results in a machine performing the functions of:
-
receiving by an application a request to open a file; determining whether the file is stored in a trusted location; in response to a determination that the file is stored in a trusted location, the application opening the file by loading the file into memory and allowing access to the file; and in response to a determination that the file is not stored in a trusted location; examining a portion of the file'"'"'s data to determine a true file format for the file; determining whether the true file format is of a format that is blocked from being opened, wherein an open block policy is stored in a registry and a registry key is used to set the open block policy for a file to prevent an application from opening a file of a specific file type and associated format; in response to the file not being of a type that is blocked from being opened, the application opening the file by loading the file into memory and allowing access to the file; and in response to the file being of a type that is blocked from being opened, displaying a message indicating that the file has been blocked from opening. - View Dependent Claims (12, 13, 14)

15. A method of blocking the saving of a file, the method comprising:
-
configuring at least one processor to perform the steps of; receiving a request to save a file as a true file format; examining a portion of the file'"'"'s data to determine a true file format for the file; determining whether the true file format is of a format that is blocked from being saved, wherein a save block policy is stored in a registry and a registry key is used to set the save block policy for a file to prevent an application from saving a file of a specific file type and associated format; based on the determining, blocking the saving of the file; and displaying a message indicating that the file has been blocked from saving. - View Dependent Claims (16, 17)
