Individual ARXML files or complete DaVinci Adaptive projects can be marked as read-only.
By locking, those elements are no longer available for editing. The locked elements and their setting options are displayed with the corresponding locked icon .

Note: If there is a locked reference, the corresponding reference target and all its ancestors are also marked as read-only. This is highlighted by a separate reference locked icon .
Lock ARXML Files
This strategy uses the read-only flag of the file system and may thus hinder modifications by external tools.
- Open the context menu of an ARXML file and click Properties.
- On the Resource page, activate the Read-only attribute and
- click .
Lock DaVinci Developer Adaptive Project
Mark the entire project model and its dependent project models as read-only.
This strategy is efficient if all ARXML files contained within the project should be considered read-only. Moreover, it does not utilize the file system flags and thus only affects modifications done within DaVinci Developer Adaptive.
- Open the context menu of a DaVinci Developer Adaptive project in the
DaVinci Project Explorer and
- click
Lock Project Model.
