I'm trying to copy all my files from my SSD to my HDD. The main reason for this is that I want to move everything onto my SSD, but I'm concerned that if I use a migration tool like DiskGenius, it will erase everything on my SSD. My operating system is currently on the HDD, and I think that's why my PC is running so slowly. I'd really appreciate any advice on safely copying all my files without losing anything. Let me know if you need more details!

You could use cloning software like Macrium Reflect or Acronis, but keep in mind that those programs will erase the target drive. If you want to avoid that, make sure to clone to a new, blank drive.
Could you clarify if your HDD is a mechanical drive? If so, that could explain the slowness. Ideally, your OS should be on an SSD, while you use the HDD for storage. I'm not quite sure why you're struggling to simply copy or move files within Windows.
Yes, it's just a 2TB HDD connected via SATA. I want to move my OS from this HDD to my SSD, but I’m worried about losing my files when I do that.
Do you want to swap your drives around? If you’re looking to put your OS on the SSD and then move files from your SSD to the HDD, here’s my recommendation: use Macrium Reflect; there’s a free version available. You’ll need enough space to backup everything first. Start by backing up the main drive to the SSD, then back up the other drive. Move both images to the HDD, restore the OS image to the SSD, and it will wipe everything on the SSD. After that, change the boot order in BIOS/UEFI settings to boot from the SSD. Once you’re running on the SSD, you can move the backup back to the HDD.
Here's a great guide that seems to be still relevant: [PCMag Clone Guide](https://www.pcmag.com/how-to/how-to-clone-a-hard-drive-on-windows-pc-mac) for step-by-step tips on how to clone your drive.
You can open the command prompt and use this command: `robocopy A: B: /E /COPYALL /ZB /R:0 /W:0` just replace A and B with your drive letters. This will copy everything over, including files and folders.
Will this copy every single file? I’m concerned about my games; will they still work, or do I need to redownload them?
Robocopy is awesome for keeping folders identical and working quickly; it’s perfect if you’re frequently changing files!

If I clone my HDD and then migrate the system, will that work? I'm sorry if this sounds dumb; I usually don't dive into this stuff.
