I have a Windows 7 laptop with a 200GB hard drive. Last night while putting photos on it, I noticed it is almost FULL. Only have about 200 MB free. The performance is horrible of course & I am maxed out on RAM. My question is, can I compress the drive by checking "Compress this drive to save disk space"? I've never done this before & was wondering if this woudl be a temorary solution until I can get the pics off. If I do compress it by doing this, how long do you thin kit will take & will it speed up my system?
