Abstract:
Provided are a method for processing an application file, a method and device for accessing an application file, and a storage medium. The method for accessing an application file comprises: acquiring, from a terminal application, an access request with respect to a protected file; calling, from the terminal application, an input/output (I/O) operation object having an encryption/decryption function to examine group identification information of the protected file; and determining, according to the group identification information, if the terminal application has an access right with respect to the protected file, and if so, granting the access request. The above technical solution solves a problem in which various applications in a BYOD environment can arbitrarily access a file, and thus information can be divulged easily, thereby ensuring security of file information.
