|"i have no free space on my CD Drive, how do i free up the space?"|
CD drives - or rather, the optical disks in them that you read - don't have free space, unless they're burnable and the usable data area is not filled, and even then you can only use that free space in a burning program.
If you meant...
i have no free space on my C and D Drive, how do i free up the space?
If you meant...
i have no free space on my C Drive, how do i free up the space?
It's impossible for you to have no free space on C - Windows would not work because it's swap file uses part of the free space - but you may not have enough free space.
Un-install programs you are not using in Control Panel - Add or Remove Programs.
Delete files you are not using that are not for programs - e.g. your own music, movies, pictures, documents, saved email.
Burn files you want to keep but don't use often to CDs or DVDs - delete the original files. e.g. your own music, movies, pictures, documents.
If you have a desktop computer, buy another hard drive and install it - software partition and format it in Disk Management - copy files that are not for programs to the other hard drive , delete the original files.
Most programs that did not come with Windows do not have to be installed on C. Un-install Programs you still want to use in Control Panel - Add or Remove Programs - install them again on another hard drive partition other than C.
If you have a laptop, buy yourself a larger hard drive.
If you want to keep all the data you have, or if you don't want to install Windows or your original brand name software installation from scratch and in the process lose all the personal files you presently have on C, hard drive manufacturers web sites have at least one free program that can copy the entire contents of the original drive to the larger drive, but you'll need an external hard drive enclosure ($25 or less and up) to install the larger hard drive in, or some other adapter for it, while doing that.
E.g. Seagate has MaxBlast and another one, if you get a Seagate hard drive.
