How the update operation determines whether a file is hijacked

Information in the view database of your snapshot view is used in the update operation.

Background

When a version is loaded into a snapshot view, the file size and last-modified time stamp (as reported by the UNIX® or Linux or Windows® file system) are recorded in the view database. These values are modified each time you check out a file, check in a file, or load a new version into the view.

The update operation

When you update a view, the current size and last-modified time stamp of a non-checked-out file are compared with the size and time stamp that it recorded in the view database. If either value is different from the value in the view database, the file is considered hijacked. Changing only the read-only permission (on UNIX systems or Linux) or attribute (on Windows systems) of a non-checked-out file does not necessarily mean that the file is considered hijacked.
