To secure your data from viewing by other users, it is enough to put all the files intended to protect the files into one folder and put a password on it. There is no built-in tool to install the password, so you have to use third-party software.
Install the password in WinRar. Right-click on the folder you want to protect, and select "Add to Archive". Determine the name of the archive and leave a normal data compression to save time. Check the box next to the "Delete Files After Archiving" so that the files placed in the archive do not leave unprotected copies on the disk. Click "Set Password" and set the password. For more security, check the "Encrypt File Names" item - in this case, when opening the archive it will not be seen its contents. To open a secure archive, double-click on the file and enter the password. You can add new files using the "Add to Archive" command. Install the password to the folder using Anvide SEAL FOLDER. This small and free program does not require installation and can be launched with removable media. In addition, to save folder protection, you do not need to keep it constantly turned on. Anvide Seal Folder hides a folder from an extraneous eye and makes it visible only when entering the password. You can download the program here.Your folder disappeared from the disk. To make it visible and affordable, you need to run a program, select the secure folder in the menu, enter the password and click "Open Access".Note: If you did not create a hint, do not forget to write a password. For example, in a text file on a USB flash drive with an ANVIDE SEAL FOLDER copied to it.
All listed programs have their advantages and disadvantages. Archives do not require special skills, but not very convenient to work, problems may occur with the preservation of changes. Anvide Seal Folder does not encrypt the folder, but only hides, but it works very quickly. Flash Crypt encrypts the folder to conscience, but with large amounts of data running slowly. Therefore, choose the most user-friendly option.
