A filesystem is the way a disk or drive stores files. Claude Code compares the answer against a fixed list of filesystem types. If the system cannot answer, Claude Code treats the path as one of the listed types.\n\n**Why**\n\nIn practice, when this check cannot be completed, Claude Code takes the cautious branch and assumes the path is on one of the listed filesystem types.\n\n- Area: Linux\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
