When it comes to the privacy of files in the Windows operating system, the more common methods used by users are usually to hide the private file data. In the past, in Windows XP, Windows 7, and other operating systems, you can hide the system files, which can be easily implemented in the file properties, but such hidden methods are often easily hidden in the "folder options" folder. document. In this article, the author wants to share a different file hiding method in Win8.1.
Windows systems provide a variety of methods for file hiding, such as the system comes with hidden folders, advanced users can hide partitions, or encrypt compressed files. But if you can hide the file into a normal picture, such file hiding will be more thorough. Here's how to use the command character to hide any file into the image on the Win8.1 platform.
Putting together the information you need to hide
Hide a Docx confidential document into a normal JPG image. For example, the path of two files is placed under the D:file file. Note: The file name and path name cannot have Chinese, and the file manager of the resource manager is enabled to display the suffix function.
First, we need to use the command prompt to run some related command lines. Use the key combination Win+X to select the command prompt (administrator). Of course, if the user is not familiar with the shortcut key combination, you can also right click on the “Start” button in the lower left corner position, and the pull-up menu can also be popped up. The effect and the key combination are the same.
Select Command Prompt (Administrator)
Run Command Prompt
At the cursor at the command prompt, type copy /bd:fileimg0.jpg"text-align:center ">

We would like to explain the performance of this command. The result of the command is to copy the Win8.docx document that needs to be hidden to img0.jpg "text-align:center">

, then you can make a comparison Then everyone can see what has changed in this regard.
Image size increase
Because we just put an office document and a picture format file together, therefore, if there is a change after running the command line, then this is also the case A position or file interleaving occurs between files in two formats. After the interlacing, we compared the volume changes before and after the picture, and found that the size of the target image has increased a lot, the added part is the volume of the original Docx document. What does this mean? The contents of the office file section have been transferred to the image file.
Now, we can verify that the file transferred to the image is still the original office document. There are two possibilities for the answer. If the file transfer is hidden, then the volume part that is theoretically transferred to the image is the volume of the office document. In other words, after the image is opened, it is naturally the text information content in the office.

Click“Yes&#& To sum up, put one of the files that you need to hide (such as an office document) with another image format file. After the commands we run in the previous article, the original office document is transferred to the image file (the transfer referred to here is actually the combination of the image and the office file, and finally the content of the office document is displayed after opening). This way forms a "shadow-eye" confusing audiovisual, so that unsuspecting strangers can't find the exact file to achieve the hidden effect.
