For confidential documents that contain important information, in order to prevent others from touching and browsing, the best way is to hide them so that others cannot find them. Although the current encryption software is a lot of trouble, but it is more troublesome to use, especially once you forget the encrypted password, I am afraid that we can not open the confidential file. In fact, almost all of us use NTFS disk format now, using NTFS file stream technology, you can easily and quickly hide confidential data. It is impossible to hide confidential text information and say that it is not possible to practice it. Here is an example of how to quickly hide confidential information. Execute “cmd.exe" in the "Start"&rar; 1.txt: 2.txt”, where “XXXXXXX” represents confidential information (as shown in Figure 1). After the carriage return, the file "1.txt" can be generated in the current path, but the strangeness is the length of the file. It is 0, and double-click the file to open it and find that the contents of the file are empty. In fact, this is the "masterpiece" of NTFS file streaming technology. In this example, "ld.1.txt:2.txt" is a stream file, where "1.txt" may or may not exist, it may be a text file, or any other type of file (such as a picture, Programs, documents, etc.), the most important is the "2.txt", which is the virtual file name, of course, its suffix can also be any other file type. The full file name is not visible on the NTFS format disk. For example, in this example, you can only see the “1.txt” file, instead of “1.txt:2.txt”. If you need to view hidden data, you must open the CMD window, switch to the corresponding path, and then execute the command <;notepad 1.txt:2.txt”, you can see the hidden data in Notepad. For example, in the CMD window, execute the command “echo my bank card number and password XXXXXXX >> a.pdf:b.doc”, here “a.pdf” already exists, “b.doc” is a virtual file Name, double-click the "a.pdf" file, you can open the PDF reader to browse the original file, you can not find the ", a.pdf: b.doc" file, and the "my bank card number and password hidden in it" XXXXXXX”etc. Only hidden data can be seen by executing “notepad a.pdf:b.doc”. Hiding confidential files Use the “echo” command to edit only a small amount of text data. In fact, you can use NTFS file stream technology to hide any confidential file in the format of "type file name + suffix" > any file: Any file name + source file suffix ”, note that the "suffix" and "source file suffix" should be the same, otherwise there may be a failure to open. For example, in the CMD window, execute the command “type jimi.txt >>i:\\office.pdf:new.txt”, assuming the target disk is an I disk. In this way, the important file “jimi.txt” can be written into the <quo;office.pdf:new.txt” stream file (Figure 2). Others can only see the "stream.file" in the NTFS partition. If you open the stream file, you should use the corresponding tool. For example, the DOC file will be opened with Word. Files can be opened using ACDSEE, etc. If the handler is in the system directory, you can enter the program name, otherwise you should enter the full program path. For example, execute the command “type mypic.bmp >> hello.def:ly.bmp”, so that the “mypic.bmp” image is hidden in hello.def:ly.bmp, when you need to view it, just execute it. “mspaint hello.def: ly.bmp” Yes, for the above "office.pdf:new.txt"; stream file, you need to execute “notepad i:\\office.pdf:new.txt” The confidential file <;jimi.txt” can be checked normally.
