In all the activities that administrators do, we create a lot of files, and we use many different programs to create those files, which means that on a daily basis we create a myriad of different file types—often without knowing we have done so.
But not all file types are created equal, so I thought it would be useful to spend some time talking about the different types of files you’re likely to encounter, and the pros and cons of each, so that when you hit save, you can choose the settings that will keep your hard work in the best possible format.
Document Files (Letters, etc)
I hope that this has cleared up some confusion for you, and will point you in the direction of the best file type for your needs. I have also created an image with all of the document types described here if you want to download it and print it out. Download it here.
