Abstract

The invention provides a data processing method for a recycle bin, which comprises the following steps: generating configuration information of a service function module; receiving a data deleting request submitted by a user, and positioning data to be deleted according to the configuration information; and judging whether the data to be deleted has subdata or not, marking deletion identification for the data to be deleted and recording the indexing information of the data in a datasheet of the recycle bin if the data to be deleted has no subdata. The method can simply and effectively improve the maintainability and expandability of the function of the recycle bin in an application system on the basis of reducing the system overhead and saving the cost.

Description

technical field [0001] The invention relates to the field of data processing of a recycle bin in an application system, in particular to a data processing method for a recycle bin and a data processing device for a recycle bin. Background technique [0002] In principle, the recycle bin is a temporary data storage area for storing data temporarily deleted by users. In practice, the user may need to delete data for various reasons, for example, the user feels that the object is no longer needed, to obtain more free space, or to delete by mistake, etc., as long as the deletion operation performed by the user is not manually deleted completely ( Purge), or, because the data overflows the storage space and is lost, the data deleted by the user usually goes into the recycle bin. It can be understood that the data in the recycle bin will still occupy space, and the data in the recycle bin can be restored or completely deleted. [0003] At present, such a recycle bin function usu...
