There is no 100 percent method to prevent data file corruption. Disks wear out gradually, power supplies fail, and software conflict are some of which that cause file corruption. This article will discuss several ways to reduce your Powerpoint files from being damaged.
Do not Work Directly On Removable Media
Refrain from working your data directly on removable media such as Floppy disks, CD-ROMs, Zip or Jaz disks, USB flash drives. Only use these removable media as backup or to transport the data.
It is a good practice to use Windows Explorer to copy the required data file to your hard drive, and then open and work on it from there. Upon finishing your work, save the data file from the hard disk drive back to the removable media.
It is a good practice to always use the Save As command on the File menu (rather than the Save command) to save the file with a new name. In this way you always have a previous version to go back to in case you make a mistake that overwrites the earlier contents.
Ensure Constant Power Supply
An inconsistent power supply can cause corruption in files, even if the power does not completely go out. If the power supply spikes or is not sufficient, it can affect the read/write processes of your computer, resulting in corruption. If the power supply in your area is inconsistent, purchase a surge protector. Surge protectors are relatively inexpensive and will help protect your system from power spikes. You may also consider investing in an uninterruptible power supply (UPS). UPS units supply your computer with power even during a power outage.
Practice Good Hard Drive Maintenance
Zip files Before Sending Though E-mail
It is a good practice zip the file before sending it as attachment. This will reduce the file size and hence the chance of data corruption.
(Or you could use the Winzip program to compress the file before sending as attachment)
