The values that the storage location identifier SP_ID can have and their corresponding meanings are exemplarily shown in Table 1.

Table 1

When the document is created on the first device through the creating unit 140, the storage location identifier SP_ID of the document may be 00 or 01.

For documents storing the location identifier SP_ID = 00, such documents are only stored on the first device (eg, user device) and are not allowed to be copied to the second device (eg, the storage server). Documents storing location identification SP_ID = 00 may include, but are not limited to, system documents, temporary documents, and documents related to a particular hardware device. Further, the user having the specific authority can set the document storing the location identifier SP_ID = 00 to SP_ID = 01 through the storage location setting unit 130, that is, allowing the document to be copied to the second device.

For documents storing the location identifier SP_ID = 00, such documents are only stored on the first device and have not yet been copied to the second device. The document storing the location identifier SP_ID = 00 may be the document just created by the creation unit 140 or the document just set by the storage location setting unit 130.

The copy unit 110 may copy the document storing the location identifier SP_ID=1 to the second device according to the first preset condition, and the storage location setting unit 130 may set the storage location identifier SP_ID of the document to 11.

When the user browses the content of a certain document through the first device (for example, the user device), if the storage location identifier SP_ID of the document is 01 or 11, the first device may directly open the document stored thereon; The storage location identifier SP_ID = 10 of the document, the copy unit 110 can copy the document from the second device (eg, the storage server) to the first device to enable the first device to open the document.

According to the present embodiment, the user does not need to know the actual storage location of the document. It is "transparent" for the user whether the document is stored on the first device (eg, the user device) and whether the document is present on the second device (eg, the storage server). That is, the user only needs to know that he/she has access to a document through his user device without knowing the actual storage location of the document. In addition, the actual storage location of the document can be presented to the user in a number of different ways. For example, the actual storage location of the document may be distinguished by document icons of different colors, but the invention is not limited thereto.

In the prior art, for the same document that exists on both the user device and the storage server, the user sees "two" documents stored in different places. According to the present embodiment, it is possible to provide a better user experience for the user, that is, only one document is seen for the same document user without concern for the actual storage location of the document.

According to the present embodiment, the storage location identification SP_ID is provided as a part of the attribute information of the document, but the present invention is not limited thereto. According to an embodiment of the present invention, the document management system 100 may establish a correspondence table of the managed document and the storage location identifier SP_ID for each document being managed. The storage location setting unit 130 may appropriately update the storage location identifier SP_ID corresponding to the document in the correspondence table in response to an operation performed on the document. FIG. 3 shows an example of updating the storage location identifier SP_ID corresponding to the document through the correspondence table.
