U disk use more and more widely, today teach you to use NTFS file permissions to create a secure U disk. To create a secure USB drive with NTFS file management permissions, proceed as follows:

First, we set up the U disk as a folder directory: System, work, TMP, important files saved in the "work" directory, only add files can not be casually deleted: "System", folder to save some fixed files, similar to the computer system level, can not be changed, can only read: TMP save temporary files, can be operated arbitrarily. Then convert the USB drive to the NTFS file system method A lot, can be implemented by "Run" command cmd: Converth:/fs:ntfs.

Second, right click on the "Work" folder, select "Properties → security → advanced → permissions → edit", the object name select Everyone, deny delete subfolders and files, delete, change permissions, take ownership of the 4 items, and apply to: only the folder, subfolders and files.

Third, for the TMP directory, we do not have to control it. This completes the basic security USB drive Setup. If this is based on adding Aoutorun.inf and 3 folders with the same name as the EXE file "read-only settings", Operations like "System" folder, you can to a certain extent, the Y-disk virus immunity. Finally, don't forget to enter "Attrib+r+h+s" in the command line "file name" command to set the four files read-only hidden and system properties, to avoid being deleted without exhausted.

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

PS: The use of NTFS file permissions to create a secure U-disk method is very effective. U disk Exchange data between the computer is very convenient, but if the virus or the file is mistakenly deleted can be bad, to create a different folder to set different permissions of the security U disk, you can secure the U disk.
