How to make a partition bigger?

[jbtrade]

So after installing windows 7 I now have 30 gigs of space. I'm wanting to make my partition larger using a program. My question is, will this affect my mac osx side? And, what program do you guys recommend?

go into OSX and use disk utility and you can resize the partition as long as you have the extra space available.

There isn't any options to resize the partition in utilities.

Yes there is

Finder > Applications > Utilities > Disk Utility

Click the drive you want on the left, select the partition tab along the top, set the desired size.

NOTE: Although it's supposed to be able to do it with no problems, it's strongly recommended you back up your HDD before adjusting any partitions in case you have problems.
