There are many tutorials on the web that guide users on how to camouflage files or folders to hide private files from being easily detected. It is true that for private files on computers, especially public computers, how to hide them and even encrypt them is a headache for users. Users who use Windows 7 have a very good function, this function can help users to virtualize a hard disk, users only need to save the private files in this virtual hard disk, you can achieve the purpose of "hidden" files, and even Encrypt this virtual hard disk with unbreakable BitLocker encryption to ensure data security and see how it works. First of all, we have to create a virtual hard disk, the operation is "start → search → diskmgmt.msc", after entering the disk management operation interface. In the "Disk Management" interface, select “Menu → Operation & Rarr; Create VHD”. In the pop-up "Create and attach virtual hard disk" interface, the "Location" option is the file storage location used by the virtual hard disk (this virtual hard disk is actually a vhd file, no matter how many files the user stores in this virtual hard disk. , are all merged and stored in this vhd file.). "Virtual disk format" is divided into "dynamic expansion" (automatically expand the vhd file size with the file size stored inside) "fixed size" (limited storage file capacity for user-set size). After successfully creating a virtual hard disk, the user can find the virtual hard disk in the “Disk Management” interface. The first thing to do is to initialize it and initialize it before using the virtual hard disk. This is also true. The hard drive is the same. The specific operation is "virtual hard disk icon → right-click menu → initialize disk". Similarly, this virtual hard disk also needs to be partitioned and formatted before it can be used. (virtual hard disk area → right-click menu → new simple volume & rarr; next → input partition capacity & rarr; next & rarr; next & rarr; choose to format this volume & rarr; next & rarr; completed). After the above steps, the user creates a virtual hard disk, and the user can store his private file to the virtual hard disk as usual. Some netizens will ask, this virtual hard disk, all users can access, then how to achieve the purpose of confidentiality? When the user stores the private file to the virtual hard disk, you need to leave the computer, you can put this virtual hard disk “ Offline"(in the "Disk Management" interface" virtual hard disk icon → right-click menu → offline”), the virtual hard disk will not appear in my computer, when the user needs to use When you choose to connect this virtual hard disk "online", you can. For more confidentiality, you can choose to “separate VHD”. In the “Disk Management” interface, “Virtual Hard Disk Icon & Rarr; Right-Click Menu & Rarr; Separate VHD” (Do not select the option to delete the virtual hard disk after deleting the disk, otherwise the files you stored in the virtual hard disk will be wiped out. ), this way, I can't see this virtual hard disk in the disk management interface. When the user needs to use, select “Add VHD" (in the "Disk Management" interface“Menu → Operation & Rarr; Attach VHD→ Browse to find the virtual hard disk file”). For the vhd file corresponding to the virtual hard disk, the user can store it to various places of the real hard disk, and even rename it to the Windows directory, such as "xinstall.dll", so that it can be Hidden into the Windows file ocean, no one will easily find this file, but also have to be very familiar with the Windows system. Of course, you can remember this file name, and when you need it, rename it to (*.vhd) and you can use it. Still not at ease, then you can choose to encrypt this virtual hard disk with BitLocker, open BitLocker encryption function and use high-intensity password, the private file stored in this virtual hard disk can be assured, others will get your virtual hard disk instantly. Vhd file, without a password, can't open the private file stored in the view.
