Windows 10: moving my os from a 2 tb drive to a 500 gb drive

later im wiping my pc and with my new drive i want to move the os to my smaller drive. its currently installed on a 2 tb drive i want it on my 500 gb drive. in the end i wish to have windows 10 and driver updates on its own drive and all of my other data on another

:)

 

Folder size appearing in TB whereas I have only 500 GB of hard drive storage

Folder in D drive created last December, copied from android phone (working properly back then), now seems to be of 3 TB in size and every jpg image is of 26.1 GB and the videos/mp4 files are of 27 GB or larger. The files aren't opening and my entire
hard drive space is only 500 GB, so having 3 TB sized folder is out of question.


Details -

OS Version is Windows 10 2004 and OS Build is 19041.329

ACER E5-571 Series, 4 GB RAM, 500 GB Hard drive space

 

Move OS Windows 10 32 bit to new hard drive and change to 64 bit

I have a custom pc; AMD A8-7670K Processor, 8.00 GB RAM, Windows 10 Home 32-bit edition. Currently the OS is installed on a 500 GB drive but I recently added a 1 TB faster drive that I would like to move the OS to. In addition to moving the OS, I also would
like to change from 32-bit to the 64-bit version.

What would be the proper order to accomplish both tasks, moving OS and upgrading to 64-bit? Would it be best to change to 64-bit and then migrate to the new hard drive or does it really matter?

 

Is there a limit in GB/TB external drive to be used on a Laptop

On a laptop there is one USB C-port, two USB 3 ports and a normal USB port.
I got external drives such as
1, 2 TB,
2, 500 GB x2,
3. 250 GB x2
all these use some kind of power right? I wonder if there is any limit in Bytes MB/GB/TB I can use on one laptop?
Or using more (I mean in Bytes) External hard drives will slow down computer,

Any explanation in this regard will be much appreciated.
Thank you.
