When do you need to clean the USB drive?

A USB flash drive or a pen drive is a convenient tool for our work and study. Users can use it to store many files and easily share them with other people on the computer.

▶ Case No.1
Although the capacity of your USB flash drive is large, however, after using a long time, there is no more free space, you can no longer store data files with it. And since you never check the files before, you don’t know which files can be removed. In this case, you may free up even more space by cleaning your flash drive and then reusing it.

▶ Case No. 2
Your flash drive is either outdated or corrupted. Some of you might wish to fix it without formatting, while others will most likely have a new one. Have you ever contemplated permanently erasing all of your data for reusing? In this case, you must clean your USB drive to avoid the leaking of sensitive information.

▶ Case No.3
If your USB flash drive becomes infected by mistake and you want to entirely remove it. It is a good idea to clean or format your contaminated flash drive if you wish to use it normally again.

Nowadays the capacity of USB is larger for saving more data, and there are various portable hard disks for those who need to store lots of important files. However, the more files are stored, the more space on the USB is smaller.


Do you meet any cases we mentioned above? Have you ever cleaned your USB? Do you just let the outdated files consume the free space on the USB gradually? Maybe it’s time to clean your pen drive thoroughly.
