how to get a file's modified date/time and size in bytes?

I guess I'm going to have to become the old geezer who complains that everyone is ruining hard drives with temp files constantly.

Ha! 

Well in this case I was looking to see if a file changed on disk, and only access it if it changed. 
I figured looking at the timestamp and size in bytes are a good way to tell. 
The problem with using this SHELL method that creates a file is, it requires at least 3 disk accesses: 

1. one to read the attributes
   
2. one to write them to a temp file, and 
   
3. one to read that file 
   
4. (and another if we want to delete the temp file)
   

Not too efficient. For a lot of cases that might not be a big deal, but for what I'm doing, it would slow things down a lot.

We have a thread somewhere to suggest new commands for QB64PE, right? Where can I suggest adding some built-in cross-platform commands to get a file's date / size / attributes (& maybe update them as well)?
