wutianyi How can I set it to display "directory-new"?
Files Gallery will normally try to resolve the REAL path of all files and folders, including symlinks, because it needs to operate on the real path. This means that the BASENAME of all items are calculated from the real path. In terms of symlinks, this means the name is extracted from the "target" item, where the symlink actually points to.
If you want to display the name of the symlink instead, I would need to look into it. It's a bit clumsy, because it will affect anything inside the symlink destination folder also.
