I want to clean up OS HDD for transfer to SSD

I currently have a 500g HDD that my OS & programs reside on and some how it's taking up around 157g worth of space.

How much does Win 7 64 itself take up, less than 70g right?

I'd really like to clean this up for when I move it to the SSD. But I'd like to do it based on how big the programs are. I tried looking in Programs New/Delete but it really didn't list every programs disk space.

Is there any way to do this?

Also should I disk de-frag the HDD before transfer to SSD? I also believe that this particular HDD is starting to go & makes noise upon start up. I also ran some test before (sorry not sure which) that scanned the HDD's & this one came up with a less than perfect rating. When I make the transfer to the SSD, do these errors also transfer with it? Also when I make Paragon backups, are these HDD disks recorded?

All media resides on a separate 1tb HDD

Thinking of getting a 250g Samsung 840 EVO

I've used this little program since 2003. It's very helpful for researching the size of folders and apps. It;s free to use for 30 days, then it's only $19. I find it an invaluable tool.

Hmm, I do understand the point of installing a new copy on a clean SSD, but I have done so much customization & hacks/cracks on various programs & things on my computer over the last 4+ years that I don't think I could ever re-create it with out spending days & days & weeks worth of time back to back.

I have never used an SSD, so I am really interested in seeing the speed increase.

If windows only needs 30gb, I could almost just get the 120gb Samsung EVO, but I might as well get the 250g because once I get all of the programs on I want, I don't want any slow down or full drive errors like I've had in the past.

Say I just wanted to clean up my current HDD, is there a program that allows me to see absolutely EVERYTHING on it and how much said program is actually taking up on the disk?

You don't need to do a fresh install. I just converted my laptop to the Samsung EVO 120GB about a month ago. Win7-64 plus installed programs is about 30GB. Since I create Macrium Reflect images on a regular basis, I used that to restore the image to the SSD. When completed, install the Samsung Magician to optimize the drive & update the firmware (if necessary).

Boot time is now about 1 minute.

That program is: http://windirstat.info/ It gives you a nice colored picture of all the files (plus the text lines).

But if your OS installation is 4 years old, I would seriously consider a new install. It probably has accumulated so much junk that it is slow.

For a transfer, see this tutorial. In there is a link for the Paragon Migration Toll. It does the job with 3 clicks and never fails. But it costs $19.95.

Well I really do want a super fast experience & I'm sure there is a lot of bloatware on my computer at this point so I would like to clean it up.

But I am really starting to get sold on the whole new-clean install idea.

I have Paragon Backup, is the Migration Tool included in it do you know?

With the Paragon Migration Tool, can I just select certain products for it to transfer, allowing me to only take what I want/need?
