When in column view in finder, there may be several columns displayed, one for each folder. Let's say the one I really care about is 5 folders deep, and so its far to the right side of the window. How can I make that folder the "root" of the column view window? Alternatively, how do I remove the left-most column/folder from being displayed?
Note that this works for me in macOS High Sierra, but as mentioned in a comment does not work in macOS Mojave.
One of the ways I know how to have the target folder be the left most column while in Column view in Finder is to do the following:
- While in Column view, highlight (select) the target folder.
- Either press ControlCommandO or right-click and select: Open in New Tab
The root of the new Tab in Column view will be that of the selected folder and you can close the now previous Tab, if you so choose.
The other way is to do as suggested in Mateus Ribeiro answer, add it to the Sidebar, as suggested, can be done by drag and drop.
Not mentioned in his answer, but another way is after highlighting (selecting) the target folder press ControlCommandT to add it to the Sidebar.
