This paper proposes a digital forensic method by an evaluation function based on timestamp changing patterns. Operations on file or folder leave changed timestamps, which give the ways to know what operations were executed. Changes of timestamps of ten operations of a file and eight operations of a folder were examined. Analyses on the changes on the eight folder operations are newly added in this paper, which are not performed in the previous works. Based on the timestamps changes of the file and the folder, two evaluation functions are proposed. The first evaluation function checks whether timestamps are changed by file and folder operations, and the second evaluation function checks whether timestamps are originated from a source file or other attribute field. By the two output values from these evaluation functions, a digital forensic investigation on the file or the folder is performed. With some cases, i. e. file copy and folder creation operations, the proposed forensic method is tested for its usefulness.

EDMS systems have been a main alternative for enterprise content management (ECM), which provide valuable functions for the effective control and management of organization-level digital contents. However, it has not been effective frequently for the purpose of integrative control of overall contents in an organization. One of reasons for this problem is that individuals usually create and store files with their own personal computers and do not move them to the central storage and control device, EDMS. Many occasions show that this situation can cause undesirable results for better management of enterprise contents. This paper introduced an approach of virtual folder which can directly connect individual computers and EDMS storage device without users' inconvenience. Adding the capacity of restricting usage of individual computer, users unavoidably and conveniently store and retrieve digital contents using EDMS server system. Several modules and implementing architecture for the virtual folder system are shown and the results of utilizing the system are explained with a case of application.

Recently, with the enlargement of cloud computing, virtual desktop infrastructure(VDI) can be an alternative of the existing personal computer based information environment. For the case of partially introduced VDI coexisting with personal computer environment, we suggest a virtual folder based approach to control the overall digital contents within an organization with a case of implementation. Although a centralizing device was used for storage and sharing of organization's digital contents, it was not easy to accomplish centralizing digital contents completely. It is tried to prevent users from utilizing their own storage in their personal computers or virtual machines and to use virtual folder which transfer and store digital contents to and in EDMS. The virtual folder system of this paper looks like a real folder in a personal computer, but it is another virtual device for outer storage devices including EDMS. It can be an alternative and reference of digital contents control for future applications of cloud computing.

Many users feel a great pain owing to losing edited files. It is very serious loss in time and money. This problem occurs because email attachments are edited in 'Inbox' and the compute immediately shuts down with 'Save'. This is caused by the illusion that the 'save' in a temporary folder is saved to a secure hard disk. Our thesis proposes a loss-prevention system WatchDog for safe storage and folder management of the e-mail attachments. The proposed system operates a warning window pop-up when we 'Open(O)' and 'Save' the attachment. In addition, convenient folder management plans for safe copying and movement are shown through example programs.

Project management is a tool for smooth operation during a full cycle from the design to normal operation including the schedule, document, and budget management, and document management is an important work for big projects such as the JRTR (Jordan Research and Training Reactor). To manage the various large documents for a research reactor, a project management system was resolved, a project procedure manual was prepared, and a document control system was established. The ANSIM (Advanced Nuclear Safety Information Management) system consists of a document management folder, document container folder, project management folder, organization management folder, and EPC (Engineering, Procurement and Construction) document folder. First, the system composition is a computerized version of the Inter-office Correspondence (IOC), the Document Distribution for Agreement (DDA), Design Documents, and Project Manager Memorandum (PM Memo) works prepared for the research reactor design. Second, it reviews, distributes, and approves design documents in the system and approves those documents to register and supply them to the research reactor user. Third, it integrates the information of the document system-using organization and its members, as well as users' rights regarding the ANSIM document system. Throughout these functions, the ANSIM system has been contributing to the vitalization of united research. Not only did the ANSIM system realize a design document input, data load, and search system and manage KAERI's long-period experience and knowledge information properties using a management strategy, but in doing so, it also contributed to research activation and will actively help in the construction of other nuclear facilities and exports abroad.

In digital forensics, the creation time, last modified time, and last accessed time of a file or folder are important factors that can indicate events that have affected a computer system. The form of the time information varies with the file system, depending on the user's actions such as copy, transfer, or network transport of files. Specific changes of the time information may be of considerable help in analyzing the user's actions in the computer system. This paper analyzes changes in the time information of files and folders for different operations of the NTFS and attempts to reconstruct the user's actions.

In recent, the interests of multi-user systems have been increased. Multi-user systems allow a number of users to access the system simultaneously. Security is one of the key issues to be addressed in a multi-user environment. We propose a solution based on the NTFS file system that provides the personal data security and considers the convenience of users. The system increases the convenience of users by simplifying the complexity of the security setting on NTFS. We also propose a variety of policies that prevent from the conflicts incurring when different users set up the personal folders simultaneously and do not set up the important folders such as the window system folders as personal folders. In addition, our system supports the function of setting up the prohibition folder lists so that no one can not set the folder to their personal folders.
