And vs. Or

Both and and or are coordinating conjunctions used to join grammatically equal elements, but each of them indicates a different relationship between these elements.

Use and to show that all listed elements are true at the same time. In terms of logic, the statement a = b and c means that:

If both b and c are true, then a is true.
If either b or c is false, then a is false.
If neither b nor c is true, then a is false.

Use or to show that only one element can be true at one time. In terms of logic, the statement a = b or c means that:

If either b or c is true, then a is true.
If both b and c are true, then a is false.
If neither b nor c is true, then a is false.

In negative sentences, use or unless the listed elements are part of the same logical unit. For example, restore of files and folders.

Important

DO NOT use and/or — this conjunction means that either all listed elements or only one of them is true at the same time. To avoid using and/or, you can do either of the following:

Use either and or or according to the described logic — in most cases, and/or can be replaced with and.
Rephrase the whole sentence or introduce a verb to list all possible options.
