Lesson 11: Working with Flash Drives
/en/osxbasics/opening-files-with-different-applications/content/
What is a flash drive?
A flash drive is a small, removable hard drive that plugs in to a USBport on your computer. You can purchase a flash drive for less than $20 at just about any retail store with an electronics department, and even at some grocery stores and pharmacies. Flash drives are a convenient way to bring your files with you and open them on a different computer. You could also use a flash drive to back up important documents and other files. In this lesson, we'll show you how to use a flash drive with your computer.
To connect a flash drive:
- Insert the flash drive into a USBport on your computer. You should find a USB port on the front, back, or side of your computer (the location may vary depending on whether you have a desktop or laptop).
- Open Finder and locate and select the flash drive from the Sidebar on the left side of the window. Note that the name of the flash drive may vary. You may also see the flash drive on the desktop. If so, double-click it to open the flash drive in a new Finder window.
If you don't see the flash drive on the desktop, go to Finder > Preferences (you may have to click the desktop first to switch to Finder). Next, make sure the External disks option is checked on the General tab.

Dec 11, 2018 From the block image, it looks like there's other stuff on the drive besides the Windows OS and programs it contains. I haven't used this specific program in a long time, and I've always used sperate hard drives for win/mac, but if the stuff not in the yellow outline isn't OSX stuff you should be fine deleting it. As for a full hard drive slowing down your Mac, it’s true. OS X uses your hard drive to swap files out of RAM and if there’s very little room to do that, your Mac needs to work harder at the.
How to work with a flash drive:
Once you've connected a flash drive, you can work with it just like any other folder on your computer, including moving and deleting files.
- If you want to copy a file from your computer to the flash drive, click and drag the file from your computer to this window.
- The file will be duplicated, and the new version will be saved to the flash drive. The original version of the file will still be saved to your computer.
- If you want to copy a file from your flash drive to your computer, click and drag the file from the window to your computer.
- If you want to remove a file from your flash drive, click and drag the file to the Trash, then click and hold the Trash icon and select Empty Trash to permanently delete the file.
To safely remove a flash drive:
When you're done using a flash drive, don't remove it from the USB port just yet! You'll need to make sure to disconnect it properly to avoid damaging files on the drive.
- In Finder, click the Eject button next to the flash drive. You can also right-click the flash drive and select Eject.
- You can now safely remove the flash drive from the USB port.

Optimized Storage in macOS Sierra and later* can save space by storing your content in iCloud and making it available on demand. When storage space is needed, files, photos, movies, email attachments, and other files that you seldom use are stored in iCloud automatically. Each file stays right where you last saved it, and downloads when you open it. Files that you’ve used recently remain on your Mac, along with optimized versions of your photos.
* If you haven't yet upgraded to macOS Sierra or later, learn about other ways to free up storage space.
Find out how much storage is available on your Mac
Choose Apple menu > About This Mac, then click Storage. Each segment of the bar is an estimate of the storage space used by a category of files. Move your pointer over each segment for more detail.
Click the Manage button to open the Storage Management window, pictured below. This button is available only in macOS Sierra or later.
Manage storage on your Mac
The Storage Management window offers recommendations for optimizing your storage. If some recommendations are already turned on, you will see fewer recommendations.

Store in iCloud
Click the Store in iCloud button, then choose from these options:
- Desktop and Documents. Store all files from these two locations in iCloud Drive. When storage space is needed, only the files you recently opened are kept on your Mac, so that you can easily work offline. Files stored only in iCloud show a download icon , which you can double-click to download the original file. Learn more about this feature.
- Photos. Store all original, full-resolution photos and videos in iCloud Photos. When storage space is needed, only space-saving (optimized) versions of photos are kept on your Mac. To download the original photo or video, just open it.
- Messages. Store all messages and attachments in iCloud. When storage space is needed, only the messages and attachments you recently opened are kept on your Mac. Learn more about Messages in iCloud.
Storing files in iCloud uses the storage space in your iCloud storage plan. If you reach or exceed your iCloud storage limit, you can either buy more iCloud storage or make more iCloud storage available. iCloud storage starts at 50GB for $0.99 (USD) a month, and you can purchase additional storage directly from your Apple device. Learn more about prices in your region.
Optimize Storage
Click the Optimize button, then choose from these options.
- Automatically remove watched movies and TV shows. When storage space is needed, movies or TV shows that you purchased from the iTunes Store and already watched are removed from your Mac. Click the download icon next to a movie or TV show to download it again.
- Download only recent attachments. Mail automatically downloads only the attachments that you recently received. You can manually download any attachments at any time by opening the email or attachment, or saving the attachment to your Mac.
- Don't automatically download attachments. Mail downloads an attachment only when you open the email or attachment, or save the attachment to your Mac.
Optimizing storage for movies, TV shows, and email attachments doesn't require iCloud storage space.
Empty Trash Automatically
Empty Trash Automatically permanently deletes files that have been in the Trash for more than 30 days.
Reduce Clutter
Reduce Clutter helps you to identify large files and files you might no longer need. Click the Review Files button, then choose any of the file categories in the sidebar, such as Applications, Documents, Music Creation, or Trash.
You can delete the files in some categories directly from this window. Other categories show the total storage space used by the files in each app. You can then open the app and decide whether to delete files from within it.

Other ways that macOS helps automatically save space
With macOS Sierra or later, your Mac automatically takes these additional steps to save storage space:

- Reminds you to delete used app installers
- Removes old fonts, languages, and dictionaries that aren't being used
- Clears caches, logs, and other unnecessary data when storage space is needed

How to free up storage space manually
Even without using the Optimized Storage features of Sierra or later, you can take other steps to make more storage space available:
- Music, movies, and other media can use a lot of storage space. Learn how to delete music, movies, and TV shows from your device.
- Delete other files that you no longer need by moving them to the Trash, then emptying the Trash. The Downloads folder is good place to look for files that you might no longer need.
- Move files to an external storage device.
- Compress files.
- Delete unneeded email: In the Mail app, choose Mailbox > Erase Junk Mail. If you no longer need the email in your Trash mailbox, choose Mailbox > Erase Deleted Items.

- The Storage pane of About This Mac is the best way to determine the amount of storage space available on your Mac. Disk Utility and other apps might show storage categories such as Not Mounted, VM, Recovery, Other Volumes, Free, or Purgeable. Don't rely on these categories to understand how to free up storage space or how much storage space is available for your data.
- When you duplicate a file on an APFS-formatted volume, that file doesn't use additional storage space on the volume. Deleting a duplicate file frees up only the space required by any data you might have added to the duplicate. If you no longer need any copies of the file, you can recover all of the storage space by deleting both the duplicate and the original file.
- If you're using a pro app and Optimize Mac Storage, learn how to make sure that your projects are always on your Mac and able to access their files.
