Data object copy/paste transfer method and device

Abstract

The present invention provides a transferring scheme for copying / pasting data objects between files, wherein, not only the filtered data objects suitable for object file format and / or function can be explicitly written into the object file, but also the information of the initial data object can be concealed written into the object file, the mapping relationship of both can be established, thereby reserving all initial information of transferred data objects during transferring between files. The user can flexibly select whether the initial data content of the data object can be used or not during transferring the data object, based on practical situation and specific requirement in the course of subsequent copying / pasting process, thus the problem of loss of information can be effectively solved in the course of transferring data object between files by copying / pasting operations.

Description

technical field [0001] The invention relates to data transfer between files, in particular to a method and device for transferring data objects between files through copy / paste operations. Background technique [0002] With the development of information technology, users can use many different computer applications to create various files, such as to record, save and edit information. The operation that users often want to perform is to transfer some data information (hereinafter referred to as "data object") stored in a file from one file to another file, or from one location in a file to another location. The copy / paste operation is the most common means to complete the transfer of data objects, and it is also a function supported by most computer applications. [0003] In particular, since different applications may have their own file formats, information loss may occur when data objects are transferred between files of different applications.

Problems solved by technology

However, the problem with this approach is obvious

First of all, the capacity of the clipboard is limited, it is impossible to support unlimited data storage, new data may flush out the original stored data

Secondly, the clipboard is usually a storage area in memory, and when the operating system 130 stops running (such as when the computer is turned off), all data in the clipboard will be lost

Also, the clipboard itself cannot be shared between different computers, nor can it be shared between different operating systems on the same computer

So when a file is created on one computer and edited on another, or when a file is created on one operating system on the same computer and edited on another, it is still possible that copy / pasted data loss of information due to transfer
