I undertand that full path can be display in tooltip but maybe it's possible to truncate it and add ellipsis.
That has annoyed me as well, for years. It's really a bug in Windows.
Windows renders those, and there isn't any way that I know of to ask how wide they can be. (Truncation is by pixel width, not number of characters, and includes the "Copy to" / "Copier dans" string or similar at the start.)
We could hard-code a width, but I'm not sure if it would be correct in all DPIs or future Windows versions.
I did just notice something which was sometimes making us put an absolute path in the tooltip instead of a relative path, which makes the problem worse. I've changed that for 13.8.1, so once that's out you should see truncated paths a lot less in those tooltips (although it will still be possible, e.g. with long folder names).
I think I found a reliable way to "..." long names. Will be in 13.8.1 as well.
