I admit I may be slow to the party on this feature/function, and there’s a good chance the rest of you have been using this trick for years.
You can sort by multiple columns in Windows Explorer or within a folder. You just use the shift-click (hold down the Shift key) command on a column.
For example, let’s say you want to sort by “type” (application, text file, etc) and then by “date modified.”
First click the “Type” column so that it shows an arrow pointing up, indicating ascending order. Hold the shift key and then click the “Date modified” column. The up arrow remains on the “Type” column, but now the date modified is a secondary sort key. Shift-click “Date modified” again to switch between ascending/descending.
Sometimes it is the easy things in life!
