I just reformatted my laptop with Windows 7 Ultimate x86. I reformat a lot of times and never once had this problem before. The problem is, I tried to backup a folder in Program Files using Winrar, I do this by right clicking on a file or folder, and choose "Add to Archive". By doing this, Winrar will create a .rar file of the file or folder you chose, i'm sure this is pretty simple since Winrar is a popular tool that almost everyone uses, it's also the same as Winzip or any other extractors.
Anyway, normally this shouldn't have any problem, but I get a message saying something like "Winrar cannot copy file, access denied" or something, I forgot the message because i fixed the problem already but it's something similar to that.
I fixed it by unticking the "Read Only" attribute for the Program Files folder, and i had to do the same for the folders that i want to backup inside the Program Files folder as well.
The thing is, this never happened to me before, even though Program Files is set to Read Only, i've always been able to overwrite or backup files using Winrar without any problem, i haven't installed anything else other than my antivirus programs and did a few windows updates, that's it, and it can't be the antivirus programs causing this since i used them for at least a year and never once had this problem.
Is this normal?? What are the reasons that may be causing this problem??
