problem of reinstall system

Dear Tag2find support,
It's exciting for me to find your software. That's exactly what I want, the one perfectly solves my problem of file management and searching!
As a green hand, I do not quite understand the function of expport/import. It says, "before importing your tags you have to restore your files to the same location". I'm quite puzzled about this. Say, I got three disks and there are tons of files with tags in them, the process of reinstallation is 1) copy all files with tags, 2) export tags, 3) reinstall system, 4) restore all files with tags into the same disk, 5) import tags. Is that correct? But how about I couldn't find a disk to restore all the tagged fiels from three disks? And, it's not very convenient to copy them into the same place because i still need them to go back and show in their original path (different disks and different folders). With tags, it's much easier to manage and search files, but different folders are still needed because folder and tag are different dimensions which make the best function when using together.
I'll need to reinstall system recently, so will you pls kindly help to answer my question so that i can get to know how to do it efficiently.
Thank you so much!
