How to Use NTFS file permissions to create a security U disk

USB disk as the current popular mobile storage device security is very important, today to teach you to use NTFS file permissions to create a security U disk. Using NTFS file management permissions to create a secure U disk operation steps are as follows:

1, 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.

2, 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.

3, set the fixed "system" folder read-only state. 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.

4, for the TMP directory, we do not 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 permissions to create a secure U disk works well. U disk in the computer Exchange data is very convenient, but if the U disk infected with a virus or file was mistakenly deleted can not be good, to create a different folder to set different permissions of the security U disk, you can safely protect U disk.
