Whenever I download a zip from email it shows corrupted. It did not extract all the files inside it. My friend email me some set of 20 photos zipped together. It shows the download size of some 1.7 mb. That is quiet short. When I download it and unzip it, there is a error on the screen that the zip is damaged. This has happened again when I asked one my office colleague to email pdf file. That too showed corrupted. I do not understand that the problem is with the zipping tool that I am using or with my attachment. What should I do now. I had re-installed winrar a number of times but did not worked well.
