Nautilus, the default File/Desktop Manager of GNOME provides a nifty in-built tool in it to select files and folders more intelligently.
The Pattern select tool is present under Edit > Select Pattern (Shortcut: Ctrl+S). This tool allows one to select files/folders that match a particular pattern. An example of selecting a range of files using this tool can be seen in the following image:
Here I’ve selected all my folders with names starting with a D using the pattern string: D*
This is a really useful tool and one can use it to select a particular file extension amongst other files in a folder, etc. Like say, if you wish to select all JPGs in a given folder, just hit Ctrl+S and type in *.jpg or *.jpeg and all those files will be selected now!
It could get more powerful with the inclusion of Regex, in my opinion, but might be unnecessary since GNOME considers all users dumb anyway
