There seems to be a discrepancy between the two paths "C:/DE2/DE2_SD_Card_Audio/" and "C:/DE2/DE2_demonstrations/DE2_SD_Card_Audio"Did you move the folder after installation?
no，I never moved the folder。the project directory is "C:/DE2/DE2_demonstrations/DE2_SD_Card_Audio"。and there is no folder at "C:/DE2/DE2_SD_Card_Audio/"。
