Looking to format my HDD - question about cold storage

[Roux]

Hello,

As per the title, I'm looking into formatting my SSD (I use ubuntu), and do a clean install. The reason being because things aren't optimized properly such as my second hard drive, for example.

My concern is my cold storage, using Rippex. Is it really as easy as having everything written down, and the text file named "ripplewallet" saved to a USB and I'm safe to wipe my drive?

I apologize if this seems trivial but I do tend to overthink situations such as these.

Thanks for any help offered.
