ERROR_EA_TABLE_FULL

Extended-attribute storage capacity is exhausted

ERROR_EA_TABLE_FULL is a Win32 result associated with filesystems with bounded EA metadata areas.

What the result means

The filesystem cannot store another extended attribute because its EA table is full.

What to check

  • Measure how many attributes and how much EA data are already stored.
  • Remove obsolete attributes only when their ownership and purpose are known.
  • Check filesystem-specific limits and whether migration to another format is required.
  • Review applications that create unbounded per-file metadata.

Recommended handling

Free or redesign metadata usage rather than retrying indefinitely. Deleting unrelated attributes can break security, compatibility, or application state.
