FILE ERRONEOUS DELETION PREVENTION PROGRAM AND WEB SERVER INCLUDING FILE ERRONEOUS DELETION PREVENTION FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a file erroneous deletion prevention program and the like that when deleting a markup document such as an HTML file, can efficiently prevent related files that are called also from other markup documents from being erroneously deleted.;SOLUTION: In a Web server, information about related files that are called by markup documents is stored in a file information storage unit; and when a markup document stored in the Web server is to be deleted, the file information storage unit is referred to and related files that are also used by other markup documents are excluded from deletion targets. Also when a new markup document is to be uploaded, the file information storage unit is referred to, thereby prompting the upload of related files that do not exist in the Web server and enabling prevention of identical related files from being redundantly stored in the Web server.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2016,JPO&INPIT
