This is probably related to the fact that Windows usually treats files as case insensitive, i.e., a file named alan.txt is the same file as Alan.TXT. Since renaming an unsaved tab is merely a "preparation" for saving into the file system (at some point), renaming in this manner is not allowed -- but the error message produced is poor.

[alankilborn]

(Obvious) Workaround when you have mytab and you want MyTab (for example):

• rename mytab to an unrelated name not in use on any tab (e.g. temp)
• rename temp to MyTab

Similar issue: #12396

You can't rename a unsaved file, when you only want to change the large and lower case.

There already was a PR ( #14971 ) fixing that but it has to be reverted as it caused a regression.

We can't change any file unsaved or saved file) name UPPER/lower case in Notepad++.
