Why does my kindle4 only have more than 400MB of free space

Almost, the factory said that 1G is 1000MB, and the computer recognizes that 1G is equal to 1024MB, and the difference is here.

1. Kindle does not support folders at the moment, all of them will be displayed for you. But you can categorize with your own collections;

2. There are many ways to convert PPT to PDF, and I am now using Adobe Acorobat Pro 8, which is very easy to use.

3, more look at the system is convenient for Chinese, support Chinese better, can classify, can read txt, read comics effect ideally.

Hope it helps.

1:Kindle does not support folders.,I also feel very helpless.,Because it's messy and inconvenient.

2: I'm sorry, I don't know.

3: There is a tutorial in the kindle forum.,It's roughly to copy the multi-look "package" into the kindle.,And then change a few files.,Overwrite it.,You can use the multi-look system.。

The usefulness of looking at the system is quite a lot, if you want to read Chinese e-books, the native system cannot be transcoded, so Chinese is usually garbled, and if you read more, both Chinese and English are OK And support a variety of formats Very good If you usually read English, then there is no advantage in reading more

The Duokan system is the kindle Chinese system developed by the Duokan company.

That's too much cache junk, restart your phone, just release it.

Occupied by system software.

Clean it up, what phone are you using?

A lot of built-in software, system software running will occupy a lot of memory, root the phone (crack), uninstall or turn off unnecessary software, yes, it will be saved, and in addition, you must develop a good habit of cleaning up in time!

Android phones are like this,There are too many programs that come with the phone,After root,Uninstall the own program,It is recommended that you consider changing your phone to a larger memory,For example3G,Your 400MB,Enough for me to install a game。

Android system operation occupies a lot of memory, it is recommended to flash the machine.

Normal, system files are occupied.

The system is occupied! There is a program running automatically in the background!

The phone needs memory when it runs, and the garbage generated also takes up memory.

The system itself takes up a lot of running memory, and a large part of the running memory is used as a cache.

Your memory card is not standard and uses some memory.
