want to know about apple.com.fileutil

I’ve not seen the identifier

apple.com.fileutil

before. I suspect that you’ve mistyped something, because the normal format for this would be either

com.apple.fileutil

or

fileutil.apple.com

. However, I’ve not seen either of those identifiers either. Can you post more details about where you saw this?

yes, I found out "oneDrive" of Microsoft use extended attributes(xattr) to control user access permission,

they seems to set one key/value pair "com.apple.fileUtil.PlaceholderData"/someData to xattr, but I can't know the someData structure Or what principle does it follow?

could you help me? thanks.

if someone working or worked with this field, welcome to contact me, thank you!

Thanks for replying. You're right I mistyped the identifier, it is "com.apple.fileutil". I found it in the kext list with command "kextstat". I believe I can use this kext to restrict user's access to some files, but I don't know how. Is there any way to interact with this kext?

As far as I know that KEXT and its associated extended attributes are all private.
