Is it possible to check if there is a newer version on disk of the file?

When working together in a team on the same project (without PDM)

We have set solidworks to automatically open referenced files read-only. And the collaboration tick box checked. When you want to change a part, you have to use the button "get write access". So far so good.

But sometimes the problem occurs that when your buddy changes a part, saves it and makes the file read only. And then when you want to change the part, get write access, the older version of the file in your memory is not reloaded, and so when you save the part, the changes of your buddy are discarded.

We also made a macro-button to quickly get write access of a part. That works quite fast but the problem above still occurs sometimes.

Is it possible to check in VBA if there is a newer version on disk? Just like solidworks indicates in the included picture when you reload a file.

Then at least you get a warning before overwriting a newer version on disk.

Thanks in advance.
