Hi Gabriel, It may be bad practice, but you don't always have control over the file name.
E.g. if someone shares a file with a tilde in it -- yes it is simple to rename but it is extra time, and you might not bother to rename a file without foreknowledge of this bug in the first place. Even worse, if someone points you to a read only location on a shared server, you won't even be able to rename the file, and copying might be prohibitive if it's a large file. There are also tilde files created automatically by other programs, notably microsoft office.
