Thank you, Google.
Let's check NTFS $ObjID:$O and the deleted ObjectID.
There is image files on the sample E: drive, but these files do not have an ObjectID.
Browse the image file and check the ObjectID.
Confirm that the ObjectID was given.
Let's look at the FILE record of $ObjID. In the figure below, you can find the $O index record in $ INDEX_ROOT (0x90).
At this point, $ObjID:$O does not exist.
Refer to multiple files and add ObjectID to $ObjID.
$O was created as $INDEX_ALLOCATION (0xA0). ( In my test environment $O was created with seven references, including root. )
Using the fte tool, see the result of parsing ObjID.
Delete boat.jpg which we last referred to.
By this operation, the record of boat.jpg in $O is deleted.
The fte tool can refer to deleted records if there are data remaining.
When there is no $O, ObjectID is not displayed even if you use the fet tool.
