The invention discloses a wireless virtual storage device and a method for acquiring a remote file, used for enabling a multimedia electronic device to acquire the remote file in a remote database. The wireless virtual storage device comprises a wireless network interface, a microprocessor and a bus interface, wherein the microprocessor executes a file system program to generate a virtual dividing sector; a storage media reading interface of the multimedia electronic device is connected by the bus interface, and the virtual dividing sector is hung on the multimedia electronic device; and the microprocessor logs in the remote database through the wireless network interface to generate a virtual file corresponding to the remote file into the virtual dividing sector. When the multimedia electronic device accesses the virtual file, the microprocessor loads the remote files from the remote database and guides an access path of the multimedia electronic device to the loaded remote file.
