Delete local files after synchronization

Hello,
Initially I’ve got plenty of files on my desktop computer.
After creating a nextCloud server, I transfer all thoses files on my account.
But know, I want to free space on my desktop computer by deleting old files and :

  • keep them in the cloud
  • view them in windows’ file explorer

Is it possible ?
How ?

Thanks for all
