It should be noted that the profile is divided into a plurality of different components including a file system 1, a file system 2, an application 1, an application 2, and the like, and the storage information of each component is recorded in the profile information management table. Therefore, the profile information management table may be partitioned, and the storage information of the file system and the storage information of the application may be recorded correspondingly, and specifically, the components include a file system component and an application component, and the information management table of the user configuration file is built in the RAM memory, which includes:

Specifically, installing a component in a FLASH memory according to an information management table, and synchronizing the information management table to the FLASH memory, including:
reading an information management table in the FLASH memory to obtain a storage address and a storage capacity of the component;
and installing the components in the FLASH memory according to the storage addresses and the storage capacity of the components.
Based on the above, the storage address and the storage capacity of the component are determined by reading the information management table in the FLASH memory, so that the corresponding file and application are installed in the FLASH memory space according to the content recorded in the profile information management table.
It should be noted that, the component to be deleted can be determined rapidly through the profile information management table, so that the component to be deleted is deleted, and recovery and release of the completed space are realized. Therefore, when the file and the application are deleted, the quick deletion of the target can be completed directly through the file information management table, and the method specifically further comprises the following steps:
