As shown in the figure, when I drag the folder into Sublime Text, a tree-like information will be displayed. That’s fine. Then, when I add compressed files and the files after decompression, they won’t be displayed in the tree structure, and there is no refresh option in the right-click parent menu.
This is usually caused by the operating system running out of file watchers. You should see a related message in the console (View > Show Console). If restarting Sublime Text does not work, I suggest rebooting your computer.
Note you can refresh the folders manually using the menu Project > Refresh Folders.
I find that this can happen if I’ve not rebooted my Mac for some time (I often go weeks between reboots), especially if you’ve connected to network drives that are no longer present.
