Check a drawing files date befor opening

[richie_hodgson]

Is there a way to check a drawings date with lisp prior to opening it

What I want to achieve is copy a file from one directory to another but only if it is a laer version.

I can do the copy with vl-filecopy and this will probably take an unnoticeable amount of time as the file will be quite small but I am interested to see if this is achievable.

Check the following links. The second one is about scripting file system objects and may require some deep digging using (vlax-dump-object) to find what is available.

True, That is exactly what I used. Also, look into  vl-file-systime.

Holler if you need help with this.

Stupid me, I did not check the posted link 😄

You can also leverage xcopy with the '/D' switch to do this .. HERE is a link to some code that you can use within AutoCAD.

That does sound promising. I will have a play and see what I can come up with.
