Create a free encrypted USB flash drive

Usually we are used to storing a large number of files in a USB flash drive, through which it is easy to transfer files, but an indisputable fact is placed in front of us, that is, the file Security. The general U disk does not have the encryption function, and anyone can see the contents through the U disk. The price of the encrypted U disk sold on the market is relatively expensive. After the purchase, it wastes the existing U disk. How can the U disk be used? Introduce a software specifically for mobile hard disk (or U disk) folder encryption - "high-strength U disk folder encryption", this software uses a unique security encryption algorithm, it is very convenient to solve the use of U disk Security.

The encryption method of the high-strength U disk folder encryption tool is very simple. It is a green software. After downloading it, unzip and run the "high-strength U disk folder encryption .exe" executable. The file opens its interface (Figure 1). It is divided into two encryption methods: "fast mobile encryption" and "strength compression encryption".

First, fast mobile encryption

The advantage of fast mobile encryption is that the encryption speed of the folder is fast, the security is high, and the encryption of 10GB of data takes less than 3 seconds. It is also the default encryption method for the software.

Encryption of files

We first select the "Open" button on the interface, find the folder to be encrypted in the U disk, and then click the "Encrypt" button, then a popup will pop up. A dialog box for entering a password, enter the password for the folder encryption, and then confirm the folder to encrypt the folder. At the same time, we can see from the resource manager that the icon of the encrypted folder becomes a lock icon, so we can't copy, move and delete it, otherwise a dialog box will pop up. Remind you that "cannot delete files" and so on (Figure 2).

Tip: After the first run, the software will automatically add the “Mobile Encryption” command to the right mouse button menu. If there is no “Mobile Encryption” start button in the folder right-click menu, you can run it. After the software, click the “Advanced Settings” icon in the lower right corner of the window to enter the “Advanced Settings”.

Viewing and Modifying Encrypted Content

When a folder is encrypted, if you want to view the contents of the encrypted folder, just double-click the encrypted folder and a password will be displayed. The dialog box, just enter the correct password, you can pop up a similar interface to the Explorer, so you can view the contents of the encrypted folder. It is worth mentioning that the high-strength U disk folder encryption tool can not only delete the files in it, but also delete or add files to the files, and even freely drag the files to other partitions. ,Very convenient. However, once the window is closed, the folder will be automatically encrypted again.

Decryption of Folders

Decryption of folders is relatively simple. Right-click on the encrypted folder and select the "Mobile Encryption" command in the shortcut menu that appears, then In the pop-up dialog box, enter the decrypted password to complete the decryption of the folder. Second, the intensity compression encryption

The strength compression encryption operation method is the same as the encryption and decryption operation described above, but it is only the intensity compression encryption relative to fast mobile encryption, its biggest feature is that you can put a folder Compress and encrypt into an EXE file, so that we can not move like a fast-moving encrypted folder, but just copy the executable file to another computer, and then enter the correct password to decrypt it after running. The security is extremely high. At the same time, it is not limited by the operating system version, and the portability is good. If you have a confidential file to pass, just pass the executable file of the encrypted folder and tell the decryption password. This feature is very rare in similar software.

However, its shortcoming is that when encrypting those large folders, the encryption speed is slower. At this time, you may wish to consider using fast mobile encryption.

Summary

The high-strength U disk folder encryption tool encryption function is very powerful, in addition to our access to its "advanced settings" to lock the hard disk and do some Security settings and IE automatic repair operations are very convenient (Figure 3). With this software, we can use the U disk with peace of mind, I believe it will become a safe assistant in your work and life!
