Xingxingda solemnly promises that all the memory cards sold are real enough capacity, we refuse to expand the card!!

We recommend that you use disk software H2testw to detect the expansion card (upgrade card) in its original shape!

 

Test whether the memory card has sufficient capacity?

Method 1:

use H2testw for testing.

method 2:

A simpler method, such as testing 8G, can store more than 7g of music or video. If all can be read normally, it means that it is a sufficient card, if it is an expansion card, only the files stored in the front section can be read (depending on the size of the expansion), and the files in the back section are damaged and cannot be read.
