(How to use: 1. Copy this encryption tool to the root directory of your U disk or mobile hard disk (not in a folder) to encrypt and hide all files on the U disk or mobile hard disk. After encryption, you can't see your files in the U disk or mobile hard disk, you can only see this tool. But it does not affect your operation on the U disk or mobile hard disk. Your newly created files will be encrypted in the next encryption. If you or someone else accidentally deletes this tool by mistake, be assured that your encrypted files are still there, just copy this tool again and use your original password to open it. 2. Put this encryption tool in a folder to encrypt only the current folder. If multiple folders need to be encrypted, this tool must be placed in each folder. Different folders can use different passwords, but you must remember the password. 3. This tool can also encrypt local partitions or local folders on the computer. If the encrypted folder is copied and moved to other computers, you will need your initial password to open it before you can see the file. Haha, it is convenient for friends who use U disk or mobile hard disk. No longer afraid of someone seeing your important files. This tool is very easy to use by yourself, looking forward to downloading it! ! !)
