U disk file capacity display incorrect problem

Taobao bought a 4G u disk, 19 pieces. After I got my hand, I found that there are many messy files in the U disk, the file name is all garbled, and can not open. Look at the capacity is more than 10 g. The actual u disk is only 4G. Excuse me, what is this?

U disk in a mess of unknown files, which is more typical poisoning symptoms. Suggest you shut down the system autorun, then use antivirus software to clean u disk. If the scan u disk, did not find a virus, and garbled files still exist, then it is quite troublesome, judge you have a great chance to buy the so-called expansion U disk. When this happens, you need to:

1, all stored in the U disk file copy out;

2, the U disk to format, see if you can format these unknown files, while looking at the end of a U disk how much capacity;

3, if the format error, or format after the problem is still, then you need to download a U disk production tools, re-production of a U disk, the amount of postpartum, u disk is not the expansion of the U disk, you can easily see it.

If it is volume production u disk, quickly and your Taobao sellers reflect the situation, to defend their rights and interests.
