No, it would not, because "Compression software works by using mathematical equations to scan file data and look for repeating patterns. The software then replaces these repeating patterns with smaller pieces of data, or code, that take up less room. Once the compression software has identified a repeating pattern, it replaces that pattern with a smaller code that also shows the locations of the pattern. For example, in a picture, compression software replaces every instance of the color red with a code for red that also indicates everywhere in the picture red occurs." - http://smallbusiness.chron.com/file-compression-decompression-930.html
For decompression, the computer just calculate again an write a temporary file in your Temp folder as in Windows. Therefore the original file is Read Only in this process. But when you put something or take out something from the archive, it can also be done with modern archive managers, like: 7-zip... In this case, you may corrupt a file.
The other chances are: that you experienced a hard-drive damage, sometimes the system used some space in the file to write other files that causes the problem; Or you experienced a virus attack;
It is always an advise for you to backup your files!
Interesting! Thanks! But if we're talking a few dozen times or so Im sure that wouldn't be frequent enough to have to do this. – Brandon – 2013-04-05T03:05:15.343
2Cloning your HD to another one every 2 years is good enough to prevent demagnetization. It doesn't really matter if you read the same ZIP one billion times, Windows does that every minute with a thousand of static system files and they don't wipe out. – Havenard – 2013-04-05T03:13:48.910
2Keep in mind that there are OS files on the disk that are read literally millions of times more often than that zip file. – Daniel R Hicks – 2013-04-05T11:11:18.710
