A New Efficient Approach to Store Data in a Cloud Server

The present study aims at introducing a new efficient approach to store data in a cloud server. The approach is applicable to a group of annotated text files, which are supported by Microsoft Word (docx, doc, pdf, etc.). Instead of the original document, an intermediate file is produced and saved as a Microsoft Excel document for each user. The file contains edited information including highlighted and underlined parts, comments, etc. Whenever a user wants to access his/her document, the intermediate file is attached to the original document and appeared to him/her. The experimental results of 50 users show that a 2.5MB file and in total, 126MB files can be reduced in size to 3MB. It means a large amount of disk space can be saved by the cloud server.
