All of a sudden, the available memory of the iPad went to 0, and a lot of things were deleted. Who c

When you plug in your device on iTunes, you'll find a lot of capacity in the other columns to format your device or back up your stuff before formatting.

Back up your important stuff first, and then try doing a factory reset.

The second senior brother upstairs is right. Hey.

It doesn't matter, it's a lot of things running in memory, press the circle key twice, and close the program in the running bar below.

If not, turn it back on.

There is no memory on the iPad, and the operation to delete the software is:

Step 1: Click on the desktop "Settings" icon.

Step 2: Open "General" and select "Dosage".

Select the program you want to delete and click "Delete".

There are 2 parts inside the iPad that can be stored

One is running memory, which is combined with the CPU to run the program. The program needs to be called up from the other two storage and put it in the running memory before it can be run, and the data generated by the operation needs to be temporarily stored in the running memory. This running memory is like someone upstairs has already said, as soon as the power is off, it will lose data, a bit like the memory module on the computer.

The speed of the program and the number of programs that can be run at the same time, in addition to the CPU, the most important thing is related to the running memory. In the same case, the larger the running memory, the faster and more it will be. This storage is the fastest to access of the three, but it is also the most expensive.

The second is storage memory, which is fixed in the mobile phone and is used to store some programs installed in the mobile phone. Some of the phone's programs must be installed in the phone's memory, or they may have little impact on the phone's speed (usually those that need to be booted up). This memory is the second fastest to access.

If you don't jailbreak, the dosage can be cleared to see your usage.

Because what you delete is the one with less memory occupation, you can delete some with high memory occupation, which are displayed above, from high to low, choose the ones you don't use and occupy more memory, and delete more memory will not take up too much.

Some software requires information to play, such as QQ, cool running. It is recommended to clear the memory, otherwise the internal storage is broken.

Here's how to fix it:

1. If the prompt appears due to an error in the operation of the system, you can restart the ipad, and it can be restored to normal after restarting.

3. It may also be caused by the problem of the software itself, you can delete the Youku software and reinstall it.

4. If necessary, you can consider restoring the system to factory settings or upgrading to the latest version.

Apple's iOS system only takes up more than 1G of space, so what you don't understand is the memory occupied by the machine's own system.

That's the Apple system that comes with it, you can't get rid of it, and if you break it, if you lose all three of it, it will come out.

The one that is used by the system, you can't see it, alas, the hard-working child.

If you need to know exactly what capacity is being used for non-app usage, you can use the following methods:

Open "Settings", go to the "General" tab, click the "Details" button to enter the details interface, find the current iOS version number, and find out the current iOS occupation size, subtract the size from it.

Log out of your current iCloud account and clear the remaining data from the account. This data can also take up the size of the system memory after being retained for a long time.

If you need to clear these data, you can upgrade iOS to clear the remaining data in the API. In this case, the size occupied is the size of iOS.

The memory of the system cannot be deleted.
