Hello, I am helping my sister again. She had Windows XP installed on her computer which only has an 11GB hard drive. Needless to say, after scanning photos for a family quilt and slideshow album it now has no free space on it. The computer is not working right, and her cd drive will not read or write. Strangely she is getting no low memory messages. I wanted her to reinstall Windows and get a fresh start but she has no installation disks. A service tech installed XP in the shop and added more RAM. Without her cd-r drive she can't copy her files. Would it be possible for her to install an external hard drive? Could she use her internal drive for the operating system, and the external drive to run her programs on? I am trying to find a solution that will keep her from losing all her files. Thank you.
