Win XP folder permissions set

User lzking problem raised:
In the NTFS format, when selecting folder properties, there is a "Security" option, I deleted all the users below, only left their own account As a result, I found that only the folder can be opened, and everything inside can't be opened. Finished, all my information can not be opened! How to do?
Problem Solving:
For XP, user permissions can only be set under a folder or disk (the entire partition) in NTFS format. If you want to set permissions for a folder, select the target folder --Properties--Security. At this time, you can see which users have permission to the target folder. In general, you can't simply delete a user by using the "REMOVE" button, because there is an inherited relationship. You can click "”Advanced" to remove the inheritance relationship under ”Permissions“, and then return to the previous level after Apply, add users and set permissions. However, this only applies if the target folder is created by the current user. I have tested this.
But some folders were created a long time ago (earlier than the current operating system) or by other users (a machine may be used by more than one person), if I use the same method as mentioned above, I may appear. The problem encountered is that the target folder can be opened, but everything in the folder cannot be read. For this kind of folder, when we open the ”target folder--Properties--Security“, we will see some users with very strange names have permission to operate on the current folder. At this time, you can look at “Advanced- -Owner“, you will see that the current owner is a weird user. If you want to change the user rights of the folder, you should first select the user below &CHANquo;CHANGE OWNER TO". Then follow the first situation and set it up.
My folder was built a long time ago, so I also encountered difficulties. The above operation is verified by my own operation practice, but there is no theoretical basis, I can't guarantee that it is completely applicable to other situations.
PS: My operating system is the English version of XP, so the above description of the corresponding function of the current system, the Chinese version of the XD can be used to correspond.
