NS_E_PDA_TOO_MANY_FILE_COLLISIONS

The destination naming policy is producing repeated collisions

NS_E_PDA_TOO_MANY_FILE_COLLISIONS (0xC00D1188) means the sync engine encountered many files that map to names already present in the target folder. This is broader than a single NS_E_PDA_TITLE_COLLISION.

Look for the systematic naming cause

Record the destination folder, generated names for several colliding items, existing device filenames, and any truncation/normalization rule imposed by the device filesystem. A short filename limit can collapse many distinct source titles into the same target name.

Correct the mapping, not each retry

Choose a destination or naming scheme that produces unique device paths, then rebuild the affected sync queue. Renaming one item at a time is unlikely to solve a systematic collision pattern and can leave the queue unstable.
