Orphan Files

Files that are not currently open, yet have unflushed data, are referred to as orphan files. Typically, orphan files appear when an application is closed or terminated before all file modifications have a chance to be flushed to external storage.

To recover orphan files, applications should enumerate them by passing the ENUM_MODE_ORPHAN flag to the EnumerateCachedFiles method, and is then free to open, flush, and/or delete them as needed.
