File Storage and organisation

How do you all organise your scan data, I must admit, until now mines been a bit messy as I’ve not quite got a tidy work flow for imports exports and merges. I’ve just done whatever, it doesn’t affect scan results, but as I now need to free up some hard drive space I’m struggling.

I need some suggestions so this doesnt happen again.

I simply label my projects.
Delete the ones that are not good.

Then i have a photo for final scaned models.

Do you keep all the scan made or clena hard disk and keep only the good one???
