COMADMIN_E_FILE_PARTITION_DUPLICATE_FILES
COM+ partition administration: exact meaning of COMADMIN_E_FILE_PARTITION_DUPLICATE_FILES
Partition export cannot proceed because components in the partition contain duplicate filenames. ExportPartition assembles files into one package namespace and detects name collisions.
Windows describes this condition as “The partition cannot be exported, because one or more components in the partition have the same file name”.
Where the result occurs
Partitions are logical containers with explicit IDs, names, user defaults, application contents, and platform enablement; operations must use the intended partition rather than assume a global namespace. In the specific case of this result, list every component file with full path, hash, owning application, and colliding basename.
Evidence to collect before repair
- Preserve full path, basename, hash, and owning CLSID for every collision; it anchors the failure to the real administration object.
- Evidence should include application and component membership within the partition, captured before a repair changes state.
- Collect export destination and package layout when diagnosing this result; without it the symbolic HRESULT is underdetermined.
- Record whether duplicate names represent identical or different bytes.
Diagnostic sequence
- produce a collision report by basename.
- determine whether binaries can be consolidated safely.
- The next diagnostic action is to rename and rebuild distinct components when their bytes differ.
- To isolate it, remove verified stale component entries through supported uninstall.
- re-export and validate that each package filename is unique.
Retry and recovery
Rename/repackage binaries with unique deployable filenames or separate applications before re-exporting.
Difference from nearby COMADMIN results
COMADMIN_E_CANTCOPYFILE is an I/O failure; it is a deterministic package-name collision discovered before copying completes.
Practical administration scenario
Two applications in one partition use different DLLs both named Common.dll, preventing unambiguous export.
