Linked custom transformers are stored in FMX files separate from FMW workspace files.

Linked custom transformers are stored in FMX files separate from FMW workspace files.

• A. False
• B. True
• C. Not applicable
• D. Unknown

Answer: (B)

Linked custom transformers live in FMX libraries; the workspace file (.fmw) references them rather than storing their definitions. In FME, you create a custom transformer and save it to an FMX file, which acts as a reusable library. A workspace can link to that transformer in the FMX, so the logic is stored separately from the workspace. When running the workflow, the engine loads the transformer from the FMX; if the FMX isn’t available, the transformer can’t be resolved. This separation allows sharing and reuse of transformers across workspaces, which is why the statement is correct.
