new added file to the folder in vba

Hi all,

I've created vba code which shows the folder name, file name with its details. I was thinking whenever there is newly added file in the folder, how can I make the details being updated in the xlsm file automatically when open next time without user key in the data in excel sheet or run the vba code again by themselve? Please see below for the code.

Thanks in advanced.

Code:

this code only gets the files from the subfolders of C:\Users\maggie\Desktop\low, it does not get files from subfolders of the subfolders, and does not get the files from the first folder

to update the list automatically you could use a timer that loops all the folders again and just adds files that are not already listed
or you can use monitor folder APIs (or scripting) with callback whenever a new file is added to the folder, it can be added to the list
if you need to monitor multiple folders it may become a bit complex
