Any reason to not put the Windows OS user app data folder on a separate drive/partition?

2

I currently have 2 hard drives on my Windows 7 PC.

  • Windows OS and Software on an SSD drive
  • Data on a regular 1tb drive

I now have to replace my SSD drive as it died however I also have another 2nd SSD drive so I now have 3 good drives. 2 SSDs and 1 data drive.

I am trying to find out if it is a bad idea to put my Windows C:\Users\Username\AppData folder on a separate drive than Windows is installed on?

This folder is updated daily from software so a backup image of my Windows drive would never have up to date data in that folder if I had to restore from a backup image.

I am just not sure if restoring from an older backup image with newer C:\Users\Username\AppData data would break anything or not.

Basically I am wanting to know what folders from Windows I should move to a separate drive to be able to restore from a backup image at anytime from an image that had just my Windows OS on it and maybe software too? Same issue with the Windows paging file?

Any ideas/comments welcomed thanks

Besides the fact its not actually supported by Microsoft? While it is possible to do it's not something Microsoft actually supports. – Ramhound – 2017-01-22T17:31:37.383

1Even if you got it to work, it doesn't feel like a particularly sound practise. Just back the darn thing up. You'll appreciate it if you ever do need the backup. – Tetsujin – 2017-01-22T18:37:42.177

Ok thanks for the comments I wasn't sure if it was a good idea or not, sounds like it's not! – JasonDavis – 2017-01-22T18:48:33.333

1While I agree that it's not supported by Microsoft, it's a shame since the %TEMP% folder actually lives inside %AppData% so you're essentially using your SSD as swap... Which is why I do it anyway, if you're careful and do it from the Windows installer prompt, it actually works quite fine. – Ginnungagap – 2017-01-23T00:16:46.363
