How to create a folder that anti-virus software can't find (1)

First, the principle is simple method clear

As we all know, the "\\" symbol in Windows is the separator of the path, such as "C:\\ Windows\\" means the Windows folder in the C partition, and "C:\\Windows\\System.exe" means the System.exe file in the Windows folder in the C partition. So what happens if there is a "\\" symbol in the file name? If "S\\" is the name of a folder, this folder is located at "F:\\" and its path is "F:\\S\\". When we try to access, Windows will mistakenly think that the file we want to open is a folder named "S" under the F partition, not the "s\\" folder, so Windows cannot open the folder accurately, and will An error message is returned because the above path does not exist.

Second, build a directory and travel

Know the principle, then simply create a "S\\" folder under Windows XP. Why? The system will prompt "File name cannot contain ‘\\' symbol". It seems that Microsoft has already thought of this, and it seems that there are other ways to create this "special" folder.

Execute the "cmd" command in the "Run" column, open a command prompt window, enter the "c:\\" command (without quotes, the same below), and then after "c:\\" Type "mkdir s..\\" and press Enter. Now, open the Explorer and you can see that a folder named "s." is created under the C drive, but this folder can neither be opened nor deleted. Can't open because its actual path is "c:\\s..\\" (because it was created by us, we can determine its actual path), but in the System Explorer, its folder name becomes "s.", so when trying to open it, the system actually tries to open "c:\\s.\\", which of course can not be opened. Since the system thinks that the folder does not exist, it will report an error and it cannot be deleted for this reason.

If you type mkdir s...\\ after pressing c:\\, press Enter, you will see a folder named "s.." in the Explorer, and this folder can be opened but Unable to delete. But in fact this folder is invalid, copy any file to this folder under Windows XP, and then open it will find nothing.

Although the newly created "s..\\" folder cannot be opened and cannot be deleted, it does not prevent us from copying files to it. However, it should be noted that once this folder is operated, a folder named "s" will be added under the current path. At this time, both folders can be opened normally, but the inside The content is empty. At this time, just delete any one of the folders, and the remaining folders will not be able to open or delete normally in the Explorer.

Since such a folder will not be deleted under Windows, you can safely save hacking tools or important files. After testing, even if you store Trojans or even virus programs, it will not be detected by anti-virus software.

Although this type of folder does not open properly in the Explorer, it can be opened via the "Run" bar, provided that the real path to the folder is known. For example, in this example, you can type "c:\\s..\\" in the "Run" field and press the Enter key to open this folder.

Three, delete operations are easy and free

Finally, talk about the deletion method of such folders. If the folder is empty, you can type "c:\\" in the command prompt window, then type "rmdir s..\\" and press Enter to delete it. If the file is already in the folder, you can type "rmdir s..\\/s" and press "Enter". When prompted "s..\\, do you want to confirm (Y/N)?", type "y" "" delete the folder.

PS, cleverly set to hide files to ensure security

We have a lot of weight when using the computer

The files you want are not expected to be seen by others, in order to These top secrets are hidden, and everyone can do their best. Simply modifying the hidden attributes often fails to achieve the desired effect, and the secret of being easily exposed is really uncomfortable. In fact, in addition to changing properties in the Windows system, there are several more clever ways to hide files and folders.

One, the sky is over the sea

This method is mainly for files that you don't want others to see. First, modify the extension of the file you want to hide, and change the extension to a type that is not in the system. *.ffh *.jjk and so on, since these files are not linked to any application in the system, these programs that are incapable or inoperable are not easily noticeable. However, the caveat is that after you complete the modification, you must remember which ones we modified. Otherwise, if you accidentally delete it, you will be in trouble.

Second, borrow chicken to lay eggs

Many friends probably know another folder in the Windows directory to store fonts FONTS directory, there is a DESKTOP.INI file below this directory, if You can't see it, you can use the find function to find this file. After finding the file, we enter the DOS environment and copy the DESKTOP.INI file in the FONTS directory to any folder we want to hide. At this point we will find that the files in this folder are suddenly gone, and all the contents are All become font files, everything in this directory seems to be the same as in c:\\windows\\FONTS. At this point the user's file has been successfully hidden. If you want to find the hidden file life is also very easy, just right click on the folder, then select the search function, find the DESKTOP.INI file, delete it.

Three, waste utilization

This method is more concealed, it mainly uses the Windows system's own recycling station to achieve hidden purposes. Of course, it is not simply to drag files or folders to the recycle bin to hide, and the above method is not available, even if you start displaying all file functions and search functions, you can not see the hidden hidden index. First enter the DOS state, then enter the recycle bin folder, enter the use of dir /a this command to find the DESKTOP.INI file, and then remove the file properties through the Attrib -s -h -r desktop.ini command, and then This file is copied to any folder we want to hide, and you will find that the folder you want to hide has now quietly turned into a recycle bin. And it will not affect the use of the original recycle bin of the computer. Even if the recycle bin is emptied, it will not affect the files inside. Of course, you may have trouble when you want to check it again. First enter the DOS state, then enter the hidden folder and put The DESKTOP.INI file in the folder is deleted. At this time, the original file is displayed again.

4, Qiao Li Ming

First enter the windows directory under the main partition, then find the Local settings folder, then enter the Temporary Internet Files folder, find the DESKTOP.INI file in the folder And copy it out. (It should be noted that this file is usually not visible, but you can find it in the right-click in the Temporary Internet Files folder and find it.) After copying this file, send it to the one you want to hide. In the folder, the files in this folder become the contents of the Temporary Internet Files folder, and the original files are hidden. Of course, using this method will make the directory you want to hide become IE's disk cache, which will add some small junk files, but at the same time, user IE's browsing speed will be improved, is it faster? Where: If you don't want this feature, you can set it as a read-only property. If you want to retrieve hidden files, just continue to right click in the hidden folder, find the DESKTOP.INI file, delete it. Well, the above are some ways to use the Windows system's own

some functions to achieve the purpose of hiding files, remember that what you want to really hide, you must not find a hundred Jiangyang thieves.
