NS_E_PDA_RETRIEVED_FILE_FILENAME_TOO_LONG
Diagnostic meaning beyond the standard message
The actionable meaning of 0xC00D1240 / NS_E_PDA_RETRIEVED_FILE_FILENAME_TOO_LONG is mapping a device object name to a legal local destination path. Keep the object generation and lower-level result attached to the result event.
Why the operation can reach this point
At the checkpoint, automatic synchronization uses a Player-to-device partnership, a snapshot of selected playlists and a queue of per-item copy, delete or retrieval operations; The sync engine owns its own running state and can reject changes while a previous generation is active. The page-specific boundary is mapping a device object name to a legal local destination path.
A working manual file copy does not prove that the Player’s partnership, playlist snapshot and synchronization queue are valid. One concrete reproduction is: a long device title expands beyond the local path/component limit.
Evidence matrix
| Evidence | Why it matters for retrieved file filename too long |
|---|---|
| Producing object and operation | device and partnership IDs, sync generation and state, selected playlist identity/version, queued item ID and direction, subscription account, target storage, progress callback and first item-specific HRESULT |
| Decisive observation | device filename, expanded local path, component lengths and target filesystem rules |
| Generation identity | Record the same disc, device, job or Player operation generation that returned this result; a reconnect or media change creates a different test. |
| Underlying result | Keep the first device, filesystem, COM, codec, DirectShow, IMAPI or BITS result seen before the Player mapped it to this result. |
| Controlled comparison | Repeat the producing call after changing only this condition: rename the device item or choose a shorter local destination. |
Decision matrix
| Observation | Interpretation |
|---|---|
| The recorded values match the boundary | The result is consistent with mapping a device object name to a legal local destination path; correct that state before changing unrelated codecs, drivers or playlists. |
| A lower layer failed before this result | Preserve that earlier HRESULT or device result because this result may be only the Player-level mapping. |
| The same call passes after one isolated change | The comparison supports the retrieved file filename too long diagnosis rather than a broad installation failure. |
| The code changes after retesting it | The boundary was passed; diagnose the new HRESULT as the next independent stage. |
It scopes the failure to mapping a device object name to a legal local destination path.
Minimal experiment
- Capture
0xC00D1240, it, the exact Player/API operation and the first timestamp at which it appears. - Save device filename, expanded local path, component lengths and target filesystem rules; do this before ejecting media, reconnecting a device, canceling a job or rebuilding the Player object.
- correlate the result with device and partnership IDs, sync generation and state, selected playlist identity/version, queued item ID and direction, subscription account, target storage, progress callback and first item-specific HRESULT.
- Reproduce once with the original source and destination, then apply only this change: rename the device item or choose a shorter local destination.
- Create a fresh operation generation and verify that the original call advances beyond the retrieved file filename too long boundary.
Do not collapse it with these results
| Related result | Different diagnostic boundary |
|---|---|
NS_E_PDA_SYNC_RUNNING | rejecting an operation that conflicts with the currently active sync generation |
NS_E_PDA_SYNC_LOGIN_ERROR | authorizing subscription content for synchronization with the providing store |
NS_E_CANNOT_SYNC_PREVIOUS_SYNC_RUNNING | starting a new generation while the device has not completed or released the previous one |
Recovery and verification
Resolve the responsible precondition by ensuring that you rename the device item or choose a shorter local destination. A successful retest must pass the same retrieved file filename too long checkpoint, not merely hide the message in a different UI path.
When verifying it, do not delete and recreate the partnership before exporting the selected playlists and recording the first failing item; otherwise the state needed to distinguish queue, account and device failures is lost.
