Why are there no security tabs in the folder properties

Q: I am using Windows XP. Why can't I find the "Security" tab in the folder properties?
A: This may be caused by the following reasons.
1. The partition where the folder is located does not belong to the NTFS format. Currently, only ACLs (access control lists) can be set for partitions in NTFS format. If the partition does not belong to the NTFS format, you will not be able to see the "Security" tab in the partition or folder properties. If you want to convert the format of the partition to NTFS, for example, convert the D drive to NTFS format, you can run “convert D: /FS:NTFS” for lossless conversion.
2. The system now has the "Simple file sharing" function enabled. Windows XP has this feature enabled by default. When the feature is enabled, you can't see the "Security" tab, so we need to cancel it. To do this, open “My Computer", click <;Tools> Menu →“Folder Options”→“View”, Cancel in the list<;Use Simple File Sharing (Recommended) ) & rdquo;, then click the “OK” button to exit.
