Windows 文件夹结构中的“访问”时间和“修改”时间有什么区别？

Question

When I access the folder using os.path.getmtime(folder_path) , it does not return the modified time of a file. os.path.getatime(folder_path) returns the correct last modified time instead.

Answer 1

On Windows, a folder's modified time is the time when the folder was last updated, not when a file in the folder was last updated.

When you create a file in a folder, getmtime(folder) and getatime(folder) are both updated.

When you edit an existing file in a folder, only getatime(folder) is updated, not getmtime(folder) .

When you read an existing file in a folder, only getatime(folder) is updated, not getmtime(folder) .

To find when the latest file was updated in a folder, neither getatime(folder) nor getmtime(folder) will help. You need to loop through the files under the folder and use getmtime(each_file_in_folder) .
