Where are process models saved?

Question

As per my knowledge, All processes data(process instance data) of a process model will be saved as .kdb files in corresponding Appian engines. But where will our process models be saved & which format will it be ? If I delete .kdb files from engines, will be effect the process model? or only it will delete the process instance data? Any thoughts ?

For an on-premise install the process models are stored in the _admin/models folder the format is .xml Deleting or archiving the .kdb's only effect the instance data for the models. Once the kdb is deleted or archived the process backed reports will no longer display that data.
