AFTER - you delete the windows file, it will still show in RECENT documents in Vectric.
By the Way - you do not delete it in Vectric.
You need to delete it in Windows explorer or some other file manager program.
Sooo - AFTER - you delete the file in windows,
Just click on the file in the Vectric recent list. It cannot open because you deleted the windows file, and you will get a message, something like - cannot find file.
At that point it will no longer be displayed in the recent list.
Just because it is displayed as a recent file list does not mean that it actually exists.
It just means that it is something you recently worked on.
