The only problem users might have with Sumatra PDF is the folder left behind after the program is removed. Putting it on a USB worked really well - we tested it across several different computers with different operating systems and found it to work as intended. The software accomplishes this by being very small in size and portable. Probably the best thing about Sumatra PDF is the ability to put it on a USB drive to carry around. The option to view PDFs in full screen and rotate pages make Sumatra PDF the defacto PDF reader for doing nothing else but reading PDF documents. With the built in Search Box, users can locate text within a PDF document with relative ease. Basic features like zooming in and out, book views, select single page, and facing page are all present, so the program is not too simple to the point where it is unusable. Sumatra PDF reader works well in this respect, because it lacks the advance features compared to the popular Adobe Reader but is very fast. Reading PDF files is a common task that is done on a daily basis by thousands of computer users, so having the right tool is very important. There are no confusing features, nothing here that would have the user straying too far from the simple goal of reading PDF documents. Sumatra PDF is for the sole purpose of reading PDF files, and nothing else. It doesn’t have all the extra features found in Adobe Reader to slow it down, and that is the reason why Sumatra hits the right spot as many users who have PDF readers only use them to read PDF files and nothing else. Sometimes less can be considered as more such is the case with Sumatra PDF reader.
