How to Customize Your Mac Desktop
There are many ways to customize how files and folders appear on your desktop. You can manually arrange them, or have them sorted automatically. You can change the size of the icons, the text, and the grid spacing. A new feature in macOS Mojave is to have similar files organized into stacks. You can also select what other icons, such as hard drives, appear on the Desktop.
3 Ways To Print File Listings On Your Mac
If you need to print the list of files in a folder, you can do it using TextEdit, the Terminal or by using a special trick involving your printer. Using TextEdit is a simple drag-and-drop, but you must be working with a plain text document. By using the ls command in the Terminal, you can customize which information is included with the listing. You can also simply drag and drop a folder to an alias to your printer, but you must create that alias first.
Understanding Mac File Extensions
Need to convert a jpg image to a jpeg? Or an mov video to a mp4? Chances are you don't need to convert anything at all. You just need to change the filename. File extensions on a Mac are somewhat optional and often interchangeable. A jpg is the same as a jpeg file. Video files extensions aren't as important as the contents of the file as video file are really just containers.
4 Common Mistakes Mac Users Make When Trying To Search For Files
It is common to hear a Mac user complain that the file search function in macOS Finder doesn't find files they know are present. The reason is often that the user has made one of these mistakes. When searching for a file, the search usually starts in the folder in which the user is currently looking. You need to change the scope of your search to look elsewhere as well. By default, searches look in the content of files as well as the file names, but you can narrow your search to only the file names. If you are looking for something other than a file's content or name, you need to start the search differently. Many users search for files using Spotlight, but if you know you want a file, then it is better to search with the Finder.
Avoiding Blurry Custom Icons In macOS Mojave
A common complaint from Mojave users is that when you copy and paste a file icon to create a custom icon for a file or folder, the result is blurry. It turns out that this only happens when the icon image is not square. Convert the image to a square one, or copy a square portion of the image, and the result is crisp and clear.
Mac File Save Power User Tips
When you save a file you get to assign a name and pick a location. The standard save dialog provides a lot of power user techniques that most people don't know about. You can harness the power of Finder windows to choose a location, you can use keyboard shortcuts to jump to locations and cancel. You can click on existing files to inherit the same name.
Easier Ways To Open File With
The Open With command makes it possible to open a file with something other than the default app. But if you commonly need to do this with a specific app there are three ways to make it much easier to open the file with that app instead of the default. You could just drag it to the Dock icon for the app, add the app icon to the Finder toolbar, or create a keyboard shortcut.
Recreating the All My Files Finder List
Prior to High Sierra there was a Finder sidebar item called All My Files. This showed you a big list of all of your documents. This was replaced with the Recents list, which only shows documents you have opened and leaves out files you have created or downloaded, but haven't opened yet. You can easily re-create the All My Files list by making a Smart Folder and adding it to the Finder sidebar. You can customize this Smart Folder to better fit your needs.
Showing File Data In Mojave Finder
The new Gallery View in Mojave allows you to see file data for the file selected. You can choose to show more or less of this data. You can also customize this data to pick which items are shown by default. This function isn't for the Gallery View only, however, as you can also see it in all four Finder views.
Using Mojave Finder Quick Actions
A new feature in macOS Mojave is the ability to edit and manipulate files directly in the Finder using Quick Actions. You can rotate and mark up images, mark up PDFs, trim video and audio, and even convert images to PDF files. In the future you will be able to do more with third-party extensions. You can currently build your own Quick Actions in Automator too.
Using Desktop Stacks In macOS Mojave
A new feature in macOS Mojave is the ability to temporarily group files on your Desktop into Stacks. These Stacks can contain files of a similar kind, or groups organized by date or tags. You can expand and collapse any Stack to see what is inside, and use the file icons inside the Stack like regular icons. Desktop Stacks can help if your Desktop gets messy and you need to find files right now, but don't have time to organize your Desktop files at the moment.
Gallery View In macOS Mojave
The new Gallery View replaces Cover Flow View in macOS Mojave. It is useful for flipping though a folder full of images, PDFs or other document types when you need to find one using a large preview image. There are some customization options for Gallery View.
Viewing File Contents With Quick Look
Quick Look gives you the ability to view the contents of files without needing to open them up in an app. You can easily view a single photo or document by pressing the spacebar. You can also page through PDF files or view groups of photos. If you open up the Quick Look window you can continue to select different files with the cursor or arrow keys and the window will reflect whatever is selected.
How To View Folder Sizes
When you look in List View in the Finder, you'll see a file size for every file, but no size listed for any folders. You can still view the total size of a folder using one of several methods. You can Get Info on a folder to see the size and number of files. You can also use the File Inspector. Quick Look also displays the folder size. If you want to see the sizes of all folders in List View, you can enable that by changing a setting.
How To Use Tags To Organize Your Files
Instead of placing every file in a specific folder, you can tag your files for greater flexibility. Files can have more than one tag, so you can include a file with more than one project, task or collection. You can rename and assign colors to tags. You can easily view all of the files that have a tag, search for files by tag, or even create smart folders for a single tag or set of tags.
How Mac Trash Handles External Drive Files
The way the Trash works is pretty straight-forward for your internal drive. But how about files on external or removable drives? Any file you put in the trash remains on that drive, but appears as a aggregated list when you view the Trash folder. You can only see files in the Trash on the same computer and user that threw them away.
How To Copy and Paste Files In the Mac Finder
Instead of dragging and dropping files to move them in the Finder, you can simply use Copy and Paste. This will create a copy of the file in the new location. But if you hold down the option key, this moves the file instead. This is similar to cutting and pasting files in other operating systems. You can copy and paste multiple files.
Using Temporary Finder Tags To Gather Files
Tags are useful for many things. One idea is to use them to flag files to gather them together for a single use without moving the files from the folders where they reside. For instance, you may want to gather together files to send to someone or save a copy to an archive.
Getting Around a Common Custom Icon Problem
Creating a custom Finder icon for a file or folder is as simple as copy and paste. However, a common problem people experience is when they try to copy and paste a whole file as the new icon and get a generic image icon instead of the picture. The trick is to copy the image inside the file, and not the file itself.
Batch Renaming Files in Mac Finder
You can rename multiple files easily in macOS High Sierra and other recent versions of macOS. The option to do so only appears when you have selected multiple files. You can choose to simply replace text in all filenames. Yo can also add text to the beginning or end of a filename. You can also set up formatted names, such as numbering groups of files.
