Please provide your input file.

I tried to add the example file but it is 2.8MB and apparently the limit is 2.5MB. I cannot trim the file. So I need a way to upload a little but more than 2.5MB.

Use any site which allows uploading. Like google drive or similar.

What's wrong with the sites you used before, see #2462 and #4381?
