Delete or remove?

What’s the difference between delete and remove? When should you use the word “delete” on a user interface��or in a document, and when “remove”?��Here’s an explanation that makes sense to me.

Use “delete” when you’re getting rid of the thing entirely – when it’s disappearing from the data store. Use “remove” when you’re subtracting it from a group or a list, but it remains available in the data store.

An example is the model of users and groups. Let’s say the user arthurdent belongs to two groups: spacers and earthlings. When Arthur no longer lives on planet Earth, you would remove��arthurdent from the earthlings group. But if Arthur has departed the universe without leaving so much as a towel behind, you would��delete the username arthurdent.

Here’s another example. Let’s say you have a number of credit card charges, which you’re adding to two expense reports. By mistake, you’ve added one of the charges to Expense Report 1 as well as��Expense Report 2. ��So you need to��remove that charge from the report. In addition, there’s an erroneous credit card charge of zero dollars, which you can��delete without adding it to a report.

Works for me. :) What do you think?
