隨著科技的發展，現在利用電腦來處理電子檔案亦趨普遍，於是現在愈來愈多的人們會選擇利用電腦中的多媒體素材來打發休閒時間。因此，不難想像，對多媒體素材的需求愈多，則佔據電腦硬體的電子檔案便愈多，然而，這便會引發多媒體檔案管理的問題，人們可能會發現一個惱人的問題，便是他們會忘了他們目前想要的檔案是儲存於電腦何處，或甚至是不知道他們是否擁有這份檔案。而另一個便是人機介面的問題，因為幾乎每台電腦的基礎介面都是相同的，因為皆是操作系統一安裝完畢就固定了，而這樣的介面是無法幫助使用者來管理其大量的電子檔案或馬上得到他們想要的檔案的，因此目標檔案的搜尋時間亦會因為不良的介面設計而變的冗長。而現今數位相機的使用亦非常普遍了，往往經過旅遊或聚會後所拍攝的照片數量是相當驚人的，而如此大量的檔案便會引起一些管理上的問題，所以此研究將會專注在數位影響檔案管理這一部份，而另一個選取數位影像檔案來做研究的關鍵原因，便是數位影像的檔案大小不像其他影片檔這麼大，所以很容易在電腦中會有大量儲存的問題，因此也較易產生管理上的問題。
本研究主要是建構一數位影像檔案管理支援系統（Digital Image Files Management Supported System (DIFMSS)），以幫助使用者簡單地管理其數位影像檔，及不需記憶與思考便能快速搜尋到目標檔案。該系統主要由三個方法所架構成：標籤分類技術、圖形使用者介面（GUI）及接近使用者行為的操作程序。標籤分類技術可藉由圖像自身的本意來幫助使用者分類檔案，GUI可使介面更親切、更容易使用，接近使用者行為的操作程序會符合使用者在處理檔案時其認知處理的程序。並利用實驗設計，由20位清大研究所學生作為受試者，研究分類方法及搜尋方法對使用者使用需求之間的關係、數位影像檔案的數量對其管理的影響，並利用主觀問卷方式蒐集受試者操作的主觀意見。
由實驗結果可知，雖然實驗之數位影像數目不夠大，但仍能由實驗數據及主觀問卷中看出蛛絲馬跡，DIFMSS確能提供電腦及數位相機使用者一個具有意義、有效率且容易使用的大量檔案管理工具，且相對ACDSee 7.0版，DIFMSS分類及搜尋功能較符合使用者需求，尤其是在檔案大量管理之時，而DIFMSS的使用介面也較親切，比較不容易產生操作失誤。

As the development of the technology is growing, the use of computers to process e-files is much more common nowadays. Thus, much more people now enjoy their leisure time by the multimedia materials in computers. The more requirements of the multimedia materials there are, the more number of the files occupy the hard disk is. Thereupon, some problem about the management of the multimedia files arising that people may comprehend the mainly annoying problem that they don’t know where the file they wanted is saved and even may not know if such file exists in the computer. In another aspect of the human-computer interface, the interfaces on each computer screen arranged by the original setup of your operation system are almost the same currently. The searching time of the objective files may be long due to the bad design of the human computer interface. In addition, the use of digital camera is very common today. Hundreds of the digital photos taken in the travel or party can be reached easily, and it would result in problems. Therefore, this research will focus on one part of the digital multimedia materials, the management of the digital images. Another key reason for choosing this case is that the size of movie files is much larger than digital images, so the number of movie files won't be as large as the number of digital images.
This research is mainly to build up the Digital Image Files Management Supported System (DIFMSS) to help users to manage their digital images easily and search out the objective images quickly almost without thinking and memorizing. The system is constructed mainly by three approaches, the labeled-classifying techniques, graphical user interface (GUI), and the operating procedure approximate to the user behavior. The labeled-classifying techniques can classify the digital images files in many aspects by means of the files themselves to support users managing their files definitely. GUI can make the user interface friendly and easy to use. The operating procedure approximate to the user behavior can comply with the human cognitive process when managing the files. Twenty graduate students of National Tsing-Hua University participated in the experiments. Through the experiment, the effect of the number of the digital image files on classifying task and the searching task their management were investigated, and the subjective opinions were collected by the questionnaires.
Although the digital image files in the experiment were not plenty enough to get significant results, it was found that in a large number of the digital image files, DIFMSS does provide users a valuable tool which is meaningful, efficient, and easy to use by the clues from the experimental data and the questionnaires. Compared with the edition 7.0 of ACDSee, the classifying function and the searching function of DIFMSS conform to users’ requirements especially in managing a large number of digital image files. The interface of DIFMSS is friendlier than the edition 7.0 of ACDSee, and users make more mistakes in the edition 7.0 of ACDSee.
