INstalling next cloud application on WIndows error: could not create folder "/username/files"

I have a user who tried installing nextcloud on here computer. It is th enext cloud app for synchronizing.

Th esoftware runs, but in th eend, when th efoldr is to be created on their ocmputer, it gets the error:
Could not create folder “/username/files”

Why might this be happening?



She has no permissions on this folder (or just permissions to read)?

Linux system, windows system?


Sh ewas able to try again and it worked. Not sure why it did ntowork th efirst time but all is settled.
