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.
Why the operation can reach this point
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 operation is active.
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 |
| Key observation | device filename, expanded local path, component lengths and target filesystem rules |
| Controlled comparison | Repeat the producing call after changing only this condition: rename the device item or choose a shorter local destination. |
Minimal experiment
- Capture
0xC00D1240, 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.
Do not collapse it with these results
| Related result | Different condition |
|---|---|
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: 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.
