Trying to free up space on hard drive, with an external hard drive, but don't want to lose the files!

Question

So I am really stressed out right now.
I have a macbook pro, with a 750 gb hard drive in it. My internal hard drive filled up  a while back so I bought a 3TB external hard drive. I backed up my files onto my external a while ago, but I don't really remember how... There is a folder on my hard drive that is called " wd smartware.swstor" , and inside that folder is about 1.7 TB of files (when I click 'get info')... So I'm guessing that is where all my stuff is being backed up. But I also moved files from my computer onto that hard drive, like pictures and videos, that I wanted to delete off my internal... So I may have duplicates?
But my 3TB hard drive is almost full, it has 400GB free on it. And my 750gb internal hard drive on my macbook pro, has filled up again so it only has 10gb free space. So basically I have almost 3TB of files on my external hard drive, and 740gb on my internal.. This can't be right. There is no way I have this many files. I am guessing I have some of the same files on my internal that I do on my external.. Most of my files are high quality HD video files that I imported through final cut pro x....
So I bought another 3TB external hard drive that I haven't used yet. Basically, I just want to move all my files that are on my internal hard drive (roughly 750gb) onto my NEW external 3TB hard drive- and then delete the files off my internal so I have more free space. I just don't know if these files are already being backed up on my OLD external 3TB hard drive.
Can someone please help? Thank you!

If I get rid of my TIme Machine, will I lose all my files from the past?
Yes it will unless you back it up first out of TM.
TimeMachine is a self rotating image of your boot drive with saved states,  it manages itself based upon the available space on the drive. As new states are created, old ones are deleted along with older versions of your files.
Also if you incur a drastic large change to your boot drive, TimeMachine will DELETE older versions of your files.
TimeMachine is not a archival solution!
To rescue yourself from TimeMachine, you will first need to save the recent copy of file(s) to the new 3TB, then restore the older version of the file from TimeMachine to the boot drive and then rename it/date it and save that older copy to the new 3TB drive.
This way you have both the new copy and the old copy of the file pernamently archived on the new 3TB drive.
Once you have exhausted all of TimeMachines older files, you can free yourself from it, erase the drive.
For your needs, I suggest this.
Internal drive and bootable clone
1: Your internal 750GB boot drive contains active working files.
2: You have another external drive that's either 750GB or 1TB, you use Carbon Copy Cloner to make a bootable clone of your boot drive, update it when you know you have a stable OS X system on your boot drive and before updates or changes, this way if the update goes bad and the machine will not boot. You can connect the clone, hold the option key down and boot the comptuer from the clone. You then can get online to get help, or simply reverse clone your software problems away.
CCC has the ability like TimeMachine to save states between clones, it's on be default but you can turn this off as to maintain a pure clone, this is what I advise you do as to avoid confusion. You clone is a perfect copy since the last update of the clone, which you can setup to do nightly if you wish or every few days or every few weeks, whatever.
Your bootable clone is your lifesaver if your boot hard drive dies or refuses to boot up, you can boot from the clone in seconds and only be slightly off since the last update of the clone. TM won't run the computer like a clone will.
I highly adise keeping your clone in a very safe place, away from theft, fire, electrical, etc.

External Storage Drives
3: Your first external 3TB drive (sans TimeMachine) will be your storage drive, this will contain any files that you don't wish to have on the internal drive and as a result also not on the clone.
You maintain folders that are dated, with older copies of files in those folders if you wish. This way you can control the space on the drive and not make multiple duplicates of all the large files like TM does.
For instance if you work on a 100GB project for three days, instead of having three copies taking up 300GB like what TM does, you can rather choose to have just one older copy at 100GB. You can decide you don't need a particular older version of a file and remove it, thus managing your drive space yourself.
4: Your other external 3TB is a Carbon Copy Cloner backup of the first 3TB, maintain a perfect clone of that as well and update it periodically as your needs change. Since CCC can be schedualed and works in the background, you can have it update your clones overnight or another time your not using the machine. This free's up performance as TM isn't running in the background while your trying to work.
Also with no TM local cache file, that also will free up space on the boot drive.
The general rule is you need both hardware AND software protection for your data, thus with too much data to fit on the boot drive, you need a external storage drive and then a backup of that as to maintain TWO hardware copies of your data at all times.
This method is also scaleable, if you need more room than 3TB externally, you then get another 2 3TB drives, one for the new data and one for backup.
The bootable clone of your bootdrive is kept in a very safe place, it's designed to protect your OS X investment in software etc. and espectially, to get your Mac booting in as short as a time as possible while you plan on a replacement boot hard drive/repair.

Most commonly used backup methods
With your large storage needs, you basically have outgrown TimeMachine by hitting the hardware limit of drives.
If there were 10-20TB drives, you likely could keep on going with TimeMachine, but you can't.
Your clearly in the more "professional" catagory with your storage management needs, not in the TM "newbie to computers" where it's managed for you.
If your finding your needs are going to exceed 6TB, you might want to consider a external hardware RAID 5 box with 5+ drives, they will self redundancy so if a drive dies you just switch it with a new one and the missing data is copied from the other drives.
