Permissions.StickyBit Property
Syntax
StickyBit as Boolean
If True, the operating system will not allow someone to remove or rename the file or files in the directory that he does not own, even he has Read/Write permissions. This can be used for directories in which different users need to be able to create files but should not touch others' files.
If the StickyBit is set, a 1 appears to the left of the Owner's digit in the Octal representation of the FolderItem's permissions.
