I've noticed that some of my files are in blue text while others are in black. I read that the blue text files are compressed. I quess I did this with disk cleanup. I was just wondering if the compressed files loose some of its quality through the compression and if so could they be restored? Sorry if this is too off topic but I didn't want to register at another forum just to ask this. People here seem to know a lot about computer, so I thought I'd ask.
No, they won't lose any quality. Windows file compression is like zip or rar - it only compresses the file without changing the contents. You can always turn off compression provided you have enough room to hold the uncompressed versions. Something like Jpg or mp3 compression lowers the quality from the original but Windows file compression doesn't work that way.
