I have to say that i highly disagree using the above method for moving my docs. Your OS is more than capable of doing those procedures by default and much more safely and effectively. I recommend moving the whole my docs to another drive using windows built in functions. There are several benefits and no fallbacks.. You'll get faster and more reliable OS as the system doesn't have to wait for my docs when for ex handling swap files, you get enough space on OS drive to handle any project no matter how big and your downloads won't be taking the system space by accident..
The procedure is very simple. Right click 'My Documents' in any view (desktop, explorer, not start bar!!..)..) and select 'properties', First tab has 'Move' button, click that and define new address for My Docs. You get a dialog that asks if all the stuff from your previous location are moved to the new loc. Select 'Yes' and watch the magic happen as all of the contents change address and reboot to make the effect stick. After restart you won't notice the changes, every program works with no changes to preferences...
Your system is now configured properly, every windows user should do this as the first thing when installing new OS...System drive should be just for the system and programs, nothing else. I've done this since 2006 and no problems what so ever, aside from i think two poorly coded programs when i had to manually search that folder (it probably mirrored the developers folderstructures=poor code)...
I can't honestly think of any reason why you shouldn't do the relocation of my docs in the prescribed way... none. You get faster, more reliable system, huge project space, easier file management and more steady response from your SSD drive. The only slight drawback is the slower seek rate than your uber-ssd(i really am jealous, not hiding that fact...) if game uses My Docs during the gameplay and even that nuicance is because your OS drive is just faster than normal HDD... With two spinning disc drives the effect is actually beneficial, again because the single drive don't have to seek two different location at once with a single moving the head...
