Hi all,

I currently have a data overview that draws data through power query from a folder in my windows computer:

1644571630508.png


However, I plan to update this folder rapidly every week and I was wondering if it would be possible to create two macros attached to VBA codes, where they do the following:
1) The first one deletes the oldest file in the folder above (based on date modified I assume)
2) The second macro deletes the two oldest files in the folder above (based on date modified I assume)

Is this possible? And can anybody help me in creating such a macro?

It would be greatly appreciated!

Thank you so much everybody :)
