Files in subfolders are picked up when Claude works in those folders. When Claude Code loads one of these subfolder memory files, it now compares it with a known copy for the same path. If the content matches once blank space at the start and end is ignored, the file is marked as loaded and recorded as already read. It does not add another `nested_memory` attachment, and no telemetry event (usage data sent back to Anthropic) is recorded for it.\n\n**Why**\n\nIdentical memory content is not added to the conversation twice. This saves space in the conversation and avoids repeating instructions Claude already has."}
