NTFS file management permissions to create a security U disk

u disk in different computers can be very convenient to exchange files, but if the file inside the U disk infected virus or U disk inside the file mistakenly deleted can not be good, if you can create a different folder set different permissions of the security U disk, you can protect the security U disk. Let's use NTFS file management permissions to create a security USB drive.

Using NTFS file management permissions to create a secure U disk operation steps

The first step: first of all, our USB disk set up as a folder directory: System, work, TMP, important files saved in the "work" directory, can only add files can not be arbitrarily deleted: "System", folder to save some fixed files, similar to the computer system level, can not have any changes, can only read: TMP save temporary files, can be manipulated randomly. Then the U disk into the NTFS file system method many, through the "Run" command cmd: converth:/fs:ntfs to achieve.

Step Two: Right-click the Work folder, select Properties → security → advanced → permissions → edit, object name Select Everyone, reject Delete subfolders and files, delete, change permissions, take ownership of the 4 items, and apply to: only the folder, subfolders and files.

Step three: Set the fixed system folder to read-only. The same property settings, in addition to traverse, list, read properties, read Extended Properties 4 Read permission, deny other permissions, and apply to the folder, subfolders and files, so that the entire directory has read-only permissions.

Fourth step: For the TMP directory, we don't have to worry about it. This completes the basic security U disk settings. If you add Aoutorun.inf and 3 folders with the same name EXE file "read-only Settings", the operation is similar to the "System" folder, you can to some extent to the Y disk virus immune. Finally, don't forget to enter the "Attrib+r+h+s file name" command at the command line to set read-only hide and system properties for these four files to avoid being exhausted deleted.

Using NTFS file management permissions to create a U disk, you are not afraid of viruses infected U disk files or other people accidentally delete the file inside the U disk. You can also rest assured that U disk is lent to others.
