Two tips about using Trash (aka Recycle Bin) folder efficiently on KDE:
- You can configure Dolphin to automatically delete files from Trash that are older than a certain number of days. Use Dolphin menu > Configure Dolphin... > Trash > Delete files older than setting.
- You can access your Trash from command line if you have
trash-clipackage installed. (Install it by running
sudo apt-get install trash-clicommand.) Once installed,
trash-listcommand shows the contents of your Trash,
trash-putcommand moves files to Trash, and
trash-emptycommand permanently deletes everything in Trash.
