Hi, In BeOS it was quite easy using the node monitor to get a notification after the contents of a file had changed by testing if the "opcode" field in the notification message was set to B_STAT_CHANGED. Changing attribute values did not trigger that notification. It seems in Haiku however changing an attribute also triggers B_STAT_CHANGED (with B_STAT_SIZE and B_STATE_MODIFICATION_TIME set in "fields" field in the notification message). In BeOS maybe other file modifications (for instance changing the owner?) also triggered B_STATE_CHANGED. My point is that in Haiku I cannot distinguish between attribute modifications and file contents modifications anymore. Any ideas how to monitor file contents modifications in Haiku only would be appreciated. Cheers, Michael
