As long as you compress only the correct files not your boot files or anything like that , I suppose it's safe enough - but they take longer to open - not a lot but some and it depends on the size they need to decompress and there's always a risk when doing something like that that some form of corruption will occur which gets us back to the old mythology but the risk is generally considered minimal and I don't mean to overstate it - but it does exist.
Opinions vary between the experts and you'll get them from either end of the spectrum. Some will tell you it is perfectly safe and a good way to save space on your hard drive. Others will take a middle road and say they aren't positive but think it is safe but recognize that there are exceptions.
