In this post, what Other storage includes will be explained first, and then 4 practical ways to solve your iPhone Other storage is huge will be introduced in detail. 

:toc{allow='1,2,3'}

:alsoread[[iPhone System Data Huge? Here's How to Clear It](https://www.drbuho.com/how-to/clear-system-data-on-iphone)]

## What Is Other Storage on iPhone?

iPhone storage is divided into several parts. Each part is clear as its name except for the category - Other. Other storage(iOS 14 and earlier), also called System Data (iOS 15 and later), includes caches, logs and other resources currently in use by the system. This value will fluctuate according to system needs. 

So when your iPhone Other storage is huge, just start by cleaning these caches, logs, etc.

## How to Check Other Storage on iPhone?

After you have a basic understanding of Other storage, you can follow the steps below to check your Other storage:

1. Open **Settings**.
2. Tap **General**＞**iPhone Storage**. 
   ![Check iPhone Other Storage](https://www.drbuho.com/str-api/uploads/check_iphone_other_storage_3716b4ec22.png?width=400)
3. A colorful bar will show you the iPhone storage distribution.
4. To see the clear Other storage data, scroll down and tap **Other**.

In addition, using Finder/iTunes to view Other storage is also available. Just connect your iPhone to your computer＞Open **iTunes/Finder**＞Click your iPhone icon and you will see a colorful bar showing each content distribution＞Move your mouse over the bar, then you can see how much space each content occupies.

## How to Clear Other Storage on iPhone

Unlike Photos, Mail, and Apps, you can’t clear all Other storage from your iPhone, but there are various ways to reduce it. So, if you want to reduce the Other storage on your iPhone, you can try one way mentioned below or practice them all! 

### 1. Clear Safari Cache 

First, let’s start with an easy-to-do way - clear Safari cache. It saves you from tedious steps and proves to be effective in reducing the Other storage on iPhone. All you need to do is to:

1. Open **Settings**.
2. Find and tap **Safari**.
3. Tap **Clear History and Website Data**＞**Clear History and Data**.
   ![Clear History and Website Data to Clear iPhone Other Storage](https://www.drbuho.com/str-api/uploads/clear_history_and_website_data_to_clear_iphone_other_storage_2fda959db8.png?width=400)
4. Tap **Close Tabs** or **Keep Tabs** according to your needs.

Most of the time, **Automatically Save Offline** is not necessary. It saves all Reading List items from iCloud for offline reading. So just turn off it.

### 2. Update iOS	

Updating iOS contributes a lot to reducing Other storage. And it is a way recommended by Apple officials. After updating, some temporary files, caches, etc will be removed. And some new features that take up less space will replace old features, saving you a lot of space. 

Perform the following actions to check for an update: Open **Settings**＞**General**＞**Software Update**.

### 3. Clear Built-in App Cache

As you can see, the Apps is one content category shown at the colorful bar. However, here the App refers to the built-in app of iOS. With time, your iPhone may accumulate more and more built-in app caches, like Music cache, Notes cache, Voice Memos cache, etc. 

There is no way to clear these caches directly, However, you can manually clear them by deleting these apps and reinstalling them. But if there are some important data, you can make a backup before deleting it, or just delete the unimportant content in them.

### 4. Reset iPhone

[Reset iPhone](https://www.drbuho.com/how-to/reset-iphone) is one of the most effective ways to free up your iPhone space. But this will erase all your data. So before resetting your iPhone, remember to transfer your important data to your computer, external hard drive, USB stick, etc. 

Back up important data to iCloud is also a good choice. But it’s worth noting that iCloud only offers you 5GB of free space. The extra use needs to pay.

Follow the steps below to reset your iPhone:

1. Open **Settings**.
2. Tap **General**＞Scroll down and tap **Reset**＞**Erase All Content and Settings**.
3. Enter your passcode＞Tap **Erase iPhone**.

![reset-iphone-to-clear-iphone-other-storage.png](https://www.drbuho.com/str-api/uploads/reset_iphone_to_clear_iphone_other_storage_da7ddbfcb0.png?width=400)

2. Offload/delete the unused app.
3. Back up your important data to your computer, USB stick, external hard drive, etc. and delete them on your iPhone.

## What Is Startup Disk on Mac?

The disk where your current macOS is installed is the startup disk. You can check your startup disk by clicking the Apple menu > System Preferences > Startup Disk.

Most Mac users have only one disk. Thus, the Macintosh HD is the default startup disk. If you are one of the few users who have 2 or more disks in Mac, you are free to choose which one to be your startup disk.

## What Does It Mean When Your Startup Disk Is Full on Mac?

This message means that your primary disk has run out of storage capacity. This can be caused by too many files and applications stored on the disk. And what you need to do is free up disk space.

## How to Check Startup Disk Space on Mac

When the system says that your startup disk is almost full, you need to pay attention to it. To check what files are taking up your startup disk space, follow the steps below:

1. Click on the Apple icon in the upper left corner of your screen and choose **About This Mac**.
2. Click the **Storage** tab, and you will see that the storage bar is divided into sections. Every colored section represents a category. The longer the section length, the more space that category takes up. If you have free space left, it should appear at the end of the storage bar.
3. Click the **Manage** button above the storage bar to open the Storage Management Window, where you can see the size of every category.

![Check Startup Disk Usage on Mac](https://www.drbuho.com/str-api/uploads/check_startup_disk_usage_en_6bf0d060a5.png)

Alternatively, you can also know how much storage space is used or unused with the Disk Utility.

## How to Clear Your Startup Disk on Mac

By following the above steps, you know how much free disk space you have left. If you have a small amount of free space, you can use [BuhoCleaner](https://www.drbuho.com/buhocleaner) to quickly free up more disk space to avoid Mac performance downgrading. As a general of thumb, you need to keep at least 10GB of space to make sure your system is running properly.

If unfortunately, your disk is full, you may get a message that your operation could not be completed. In this case, how can you free up disk space?

This method should solve your startup disk full problem. If not, move on to the next step.

### 2. Delete Files Bypass the Trash

How do you delete files on Mac? 99% of you may move them to the Trash. But actually, these files are still stored on your hard drive if you don't empty the Trash. When your startup disk is full, most likely, you will be unable to delete files or [empty the Trash](https://www.drbuho.com/how-to/cant-empty-trash-on-mac).

<note notetype='note'>These 3 ways will delete files permanently, and files are not recoverable. We strongly recommend that you recheck files before deleting them.</note>

### 3. Use the Safe Mode

If the above methods do not solve your problem, you can clear your disk in Safe Mode.

[Safe Mode](https://www.drbuho.com/how-to/start-mac-in-safe-mode) can solve almost all problems with Mac. When you boot your Mac in Safe Mode, unnecessary startup programs are disabled. Besides, Safe Mode will remove cache files and temporary files from your Mac, which frees up some space for you.

1. Turn off your Mac.
2. Press and hold the **Shift** key as Mac starts up. 
3. Release the keys when the login window appears.
4. Log in to your Mac, maybe twice. You will see the Safe Boot words in the upper right corner of the login window.
5. Delete files you don't want and restart your Mac.

There is another way you can use. That is to move files you don't currently use to an external drive. What you should do is find an external drive, connect it to your Mac, and then move files, especially the ones that take up a lot of space and you don't need for a while.

Also, you can store your unused files in the cloud and retrieve them from the cloud when you need them.

So how to clear it? Let's take a look.

## How to Clear System Data on iPhone

While we can't get rid of system data from your iPhone, there are a few things we can do to reduce it.

To clear an app's cache files, 
1. Tap Settings > General > iPhone Storage.
2. Tap the app you want to clear, and then tap **Offload App**. (This will free up storage used by the app, but keep its document and data.)
