Windows 7: Different partitions for OS, data.. etc

Different partitions for OS, data.. etc

Im not sure if this is the right section, if in the wrong section a mod can move it. Well anyway i will be installing windows 7 over my current windows 7 RC install soon. Im planning on creating two partitions, one for the OS and another for Music, videos, pics etc. But my question is would it be smart to create a partition for program files? because if i have all my program files in in drive D lets say, and then i format C to install windows 7, the programs wont work because the necessary registry values wont be registered. Whats the point of having a separate partition for program files then?

I really want to know this so that when i format and finally install win7 i will then know what size to create the OS (C: ) partition.

Makes sense to keep data , including your program setup/installation files on a separate partition.

I always install programs on the o/s partition. The exception may be if you have a very large app. you only occasionally use - you might wish to install that on another partition.

Generally speaking, unless a program is self-contained and doesn't make any changes to the system and/or registry, then you will need to reinstall them to ensure that the correct data is written to the correct location(s). For self-contained programs, this will not apply and these can, like normal user data, be placed on a partition other than the one that the OS is installed on (even a separate INTERNAL disk) and accessed from there.

Ok after a little more research, i think its best to leave my apps on the OS partition. Because if i format at some point, i will reinstall my apps anyway to ensure all registry values are registered.

I have my OS, apps, and games stored on C, and I use the second drive, D for user data, such as my photos, music, installers, etc.

I agree ( that's what I've done).
I'd also suggest a back-ups partition for those odd programmes that you've downloaded ( and maybe for all backups). Depends on HD space.

Your program files are already installed programs that have no re-use value on reinstall so they can go with OS.

More important to preserve and backup is the Downloads file where all installers should be saved before running installations. I even back up my install and game CD ISO images there.

Then you have them all in one place when time comes to reinstall.

Ok i think its settled what im going to do. But i dont really think backing up installers is necessary because downloading them over again isnt much of a problem for me unless its a large file in which case i usually burn to a DVD. Besides i dont have that much space on my 300 gb hard disk.
