Mac: I’ve developed a lot of systems I use to keep files and projects connected on my Mac: Wiki-link services that connect notes to to-do items, Curio projects that connect emails to projects, and extensive tagging systems to keep all kinds of files together.

Each one is, in one way or another, limited in scope (and linking emails is an eternal struggle). That’s why I’m so excited about Hook.

If you didn’t know that the macOS Finder has built-in tabs, prepare for your mind to be blown — at least, if you’ve previously filled your desktop with new Finder windows when managing files. Instead of relying on Command + N, switch your finger up and to the left, and Command + T will allow you to open a ton of tabs in a single finder window.

Mac: If you have a ton of Finder windows open, management becomes a chore. How-To Geek points out there's an option that will reorganise all those windows into one tabbed window for easier management.

Mac: If you're coming over to macOS from Windows, or you just plain prefer how Windows sorts files with the folders on top and files below, then How-To Geek points to a little setting that allows you to change how files are sorted.

Mac: It is pretty easy to hunt down a file on a Mac using Spotlight, but unless you've gone looking for something very specific, you've probably never bothered to click on the "Other" tab in Finder's search panel. Six Colours reminds us just how powerful that search parameter is.

Mac: In old versions of OS X, you could simply drag any icon you wanted into the toolbar to add it. You can still do that, but as Macworld points out, you'll need to hold down the Command key in modern versions of OS X for it work.

Mac: Apple introduced tabs to Finder back with Mavericks, but if that's not enough for you, Commander One adds dual pane browsing, alongside a few other tweaks and options.

Finder is powerful and usually really easy to use with just keyboard shortcuts. That said, for some reason, you can't pop into the Tags menu to add tags without grabbing your mouse. Mac OS X Hints shows how to make a keyboard shortcut.

Mac: Finder isn't the most exciting thing about OS X, but it's the backbone for how you navigate the operating system. It's your file browser, your search engine and your management area, but few of us really dig into everything it can do. With that in mind, here are a few tips and tricks for getting a bit more out of Finder.

Apple decided to hide the Library from its users in recent OS X updates, but in Mavericks you can now change that with a simple checkbox.

Need to toss a bunch of items in a folder really fast? Mac OS X has a nifty shortcut that manages the operation in one fell swoop so you don't have to make a folder and then take further action to populate it.

Quick Look is easily one of our favourite features in Mac OS X, but it would be nice if it had a little more info about the photo you're viewing. This free plugin adds pixel dimensions and file size to Quick Look's title bar.

Mac: By default, the Finder's list view only shows you the size of individual files -- not of folders. This small, somewhat hidden setting will calculate the size of entire folders so you can see where all your data is.

Mac: Quicklook is an awesome feature that lets you quickly preview files without opening them. Here is a Finder hack that makes Quicklook even more useful: when you hit the space bar on a text document or PDF, you can select and copy text from the previewed document.

Mac: XtraFinder is a handy utility for Macs that adds browser-like tabs to Finder, as well as keyboard shortcuts, a dual pane mode for easy copying, and a few other tweaks.

In the same way you can hold down the back button in Safari, Firefox or Chrome to access your browsing history, holding down the Finder's back button in Lion shows you where you've recently been.

When you copy multiple files in OS X and the destination folder already has files of the same name, you don't have a lot of choice over what to do -- you can either cancel the copy or replace the files. This little trick gives you a bit more power.
