A good way to free up disk space is to run the windows disk clean up utility by going to "start" and in the search bar type in disk cleanup. Run it and delete all of the files it asks you want to delete. Also you can run the Disk Defragmenter utility to move files around to better places on your computer. I would suggest to download CCleaner to clean the computer.
Through the Diskpart Utility you can delete dynamic volumes. This utility can be found in the Windows 7 installation disk or the Windows 7 recovery disc.

Nothing. Temp files are created by the computer as temporary storage space. Deleting them will cause no harm to your computer. If you use a utility such as the disk-clean program built into Windows - it will delete any temp files in an attempt to speed up your system.
A simple way to delete temporary files would include using your 'disk cleanup' utility. Just click on the program and check the box next to 'temporary files.' Then confirm the delete.
I'm not sure what you are referring to by "disk management." There are many utilities to check disk usage, delete files, and manage space quotas.
