The fastest way to open a file depends on where it is

On a MacBook, you can open a file by double-clicking it in Finder, by using Spotlight search, or by opening the process first and then opening the file from inside it. Which method is fastest depends on whether you know where the file is stored, how recently you used it, and what process should open it. Most people use a mix of all three without thinking about it.

The method you choose matters less than knowing all three exist — each one solves a different problem. If you know exactly where a file sits in your folders, double-clicking is quickest. If you remember the filename but not the location, Spotlight is faster. If you want to open a file in a specific process, opening the process first gives you more control over which version of the file opens.

Key Takeaways

  • Double-clicking a file in Finder opens it in the default process for that file type, which you can change in the Get Info window.
  • Spotlight search (Command-Space) finds files by name from anywhere on your MacBook, even if you do not remember the folder.
  • Opening an process first and then using File > Open lets you choose which file to open and see recent files at the top of the list.
  • Right-clicking a file shows "Open With" options if you want to open it in a different process than the default.
  • Files in the Dock or in your Desktop folder open with a single click or double-click, making them faster to reach than files buried in other folders.

Double-clicking a file in Finder

Double-clicking a file opens it in the process your MacBook thinks should handle that file type. For a .pdf file, that is usually Preview. For a .docx file, that is usually Microsoft Word or Pages. For a .jpg image, that is usually Preview or Photos. Your MacBook remembers which process to use based on the file extension — the letters after the dot in the filename.

To change which process opens a file type by default, right-click the file, select "Open With", and choose a different process from the list. Then click "Change All" at the bottom of the window. From that point forward, every file with that extension will open in the new process. You can also change the default by clicking the file once to select it, pressing Command-I to open Get Info, and changing the "Open with" dropdown under the General section.

Double-clicking works best when you already have the file visible on your screen — either because it is on your Desktop, in an open Finder window, or in a folder you just navigated to. If the file is buried several folders deep and you do not remember the path, one of the other methods will be faster.

Using Spotlight to search for a file by name

Spotlight search finds files by typing their name, no matter where they are stored on your MacBook. Press Command-Space (or Command-Tab if you have changed your keyboard shortcuts), and a search box appears in the center of your screen. Type the filename or part of it, and Spotlight shows matching files, applications, and documents in a dropdown list below the search box.

Click the file you want in the list, and it opens in the default process. If you want to open it in a different process, press Command-Return instead of clicking, and Finder opens showing the file selected. Then you can right-click it and choose "Open With" to pick a different process.

Spotlight is fastest when you remember the filename but not where you saved it. It searches your entire MacBook in less than a second, so it is often quicker than navigating through folders. Spotlight also searches inside some files — for example, it can find text inside a Word document or a PDF — so you can search for a phrase and find the document that contains it.

Opening a file from inside an process

Open the process first (by clicking its icon in the Dock, in the Applications folder, or by using Spotlight), then use File > Open from the menu bar. A dialog box appears showing your recent files at the top, followed by folders you can navigate through. Click the file you want and click Open.

This method is useful when you want to open a file in a specific process and you are not sure which process is the default. It is also useful when you have multiple versions of a file and want to make sure you open the right one — the Open dialog shows you the full path and the date the file was last changed. Some applications, like Microsoft Word and Adobe Acrobat, show a list of recently opened files when you first open them, which is even faster than using File > Open.

Opening the process first also prevents mistakes. If you double-click a file and the wrong process opens, you have to close it and try again. Opening the process first means you control which one starts.

Opening files from the Dock and Desktop

Files on your Desktop open with a double-click, just like files in Finder. Files in the Dock open with a single click. You can add frequently used files to the Dock by dragging them there, which saves you from navigating to their location every time you need them.

To add a file to the Dock, open Finder, find the file, and drag it to the right side of the Dock (to the right of the dividing line). The file stays in the Dock until you remove it. To remove it, right-click the file in the Dock and select "Remove from Dock".

The Dock is best for files you open several times a week. If you only open a file once a month, it takes up valuable Dock space. Desktop files are visible without opening Finder, but too many Desktop files make your screen cluttered and slow down your MacBook slightly.

Using Recent files to open something you just used

Most applications remember the files you have opened recently. In the menu bar, click File > Open Recent, and a list appears showing the last 10 or 20 files you opened in that process. Click the one you want, and it opens when ready.

This is the fastest method if you are working on the same file repeatedly — for example, editing the same spreadsheet over several days. You do not have to navigate anywhere or search. The file appears in the recent list as soon as you close it.

The recent files list is specific to each process. Microsoft Word keeps its own recent list, and Preview keeps a different one. If you opened a file in Word yesterday and try to find it in Preview's recent list, it will not be there.

What to do when a file opens in the wrong process

If you double-click a file and the wrong process opens, you have three options. The fastest is to close the process and right-click the file, then select "Open With" and choose the correct process. The second option is to use Command-Z to undo the open (this works in some applications but not all). The third option is to open the correct process first, use File > Open, and navigate to the file.

To prevent this from happening again, right-click the file, select "Open With", choose the correct process, and click "Change All". This tells your MacBook to always open files with that extension in the process you chose.

Some file types have multiple applications that can open them. A .txt file can open in TextEdit, Word, or many other applications. A .jpg image can open in Preview, Photos, or an image editor. Your MacBook picks one as the default, but you can change it anytime using the method above.

Frequently Asked Questions

Can I open a file without double-clicking it?

Yes. You can press Enter or Return with the file selected, use File > Open from an process, or drag the file onto an process icon in the Dock. You can also right-click the file and select "Open" from the menu.

What does the file extension mean?

The extension is the letters after the dot in the filename — for example, .pdf, .docx, or .jpg. Your MacBook uses the extension to decide which process should open the file. You can see the extension by clicking the file once and pressing Command-I, then looking at the Name field.

Why does my file open in the wrong process?

Your MacBook is opening it in the default process for that file type. You can change the default by right-clicking the file, selecting "Open With", choosing a different process, and clicking "Change All". This changes the default for all files with that extension.

How do I open a file if I forgot the name?

Open Finder and navigate to the folder where you think you saved it. If you do not remember the folder, use Spotlight (Command-Space) and search for a word or phrase you remember from inside the file. Spotlight can search the contents of many file types.

Can I open multiple files at once?

Yes. In Finder, hold Command and click each file you want to open, then press Enter. All of them will open in their default applications. You can also drag multiple files onto an process icon in the Dock to open them all in that process.
