When you quarantine a file, SaaS Security API copies the contents
of the original file to a quarantine file in a new location. SaaS Security
API replaces the quarantine file with a tombstone file, which SaaS
Security API names
<original_file_name_with_extension>
.txt
and
saves to the original file’s location. In the SaaS Security web interface,
the tombstone includes a link to the original asset. When you restore
a file, you do so on the quarantine file, not the tombstone.
