Crawler allows you to simply create and delete custom folders. Creating custom folders can help you organize your emails.
You can create rules which will move incoming emails from a certain person into a folder bearing his/her name or you can move his emails from your crawler.
To create or delete an existing custom folder, select the "Manage folders" option in "Mail folders" menu.
To create a new folder, click on the "New Folder" button.
Fill in the name of the custom folder and click on the "OK" button. The name of folder must be unique, which means that you can't have two folders bearing the same name, even if one is spelled with capital letters and the second one wouldn't.
The newly created folder will appear on the list of folders.
You can delete only folders that you have created. To delete a custom folder, click on the "delete" link next to the folder name.
You can also rename a folder that you have created. To rename a folder, click on the "rename" link next to the folder name.
Then fill in the new name and click on the "OK" button.
