I received an archive file in my mail box which I want to open. I had no archive software, so I downloaded a free software. When I am trying to open this archive file, its showing files but I am not able to extract the files to a specific folder in my system, files come but these are in an unreadable format. It says you can't open these file I am not sure what is the problem. I just need to get this data in my system and I don't know how it can be possible. I have also rechecked with my friend who sent this archive file and he says that he is able to open the file. There must be some problem at my end. Please help me in recovering my archive file data. It is quite important for me. I have my exams next week and this material is a real life saver. Somebody give me me a solution for this.
