I think that the issue is that those files are in the same place that Local is trying to create the new sites in.
Can you try temporarily moving those site files to a different location like the Desktop and then continue with zipping each site folder and dragging and dropping it onto Local?
It depends on how Local was re-installed. If Local’s configuration folder was left intact when re-installing, then the environment info along with the various runtime things (like the raw DB files) should still be there, and Local will know about those sites.
If Local’s configuration folder was deleted during re-installing Local, then the site files will still exist, but Local won’t know anything about the actual site (hence why they seem like they have disappeared.)
Thank you Ben, what you have said makes perfect sense.
I have not change anything while installing and sure raw DB files are not deleted but I will check again.
I think your answer clerify the issue because I have reset Windows and it keep documents but delete all system files etc.
