how unload pdf files?

[feixiang]

Dear specialist，
Does anybody known how unload pdf files while use PDF Viewer EWO?
I load a pdf file like that Pdf_ewo1.load("D:/Pdfs/abc.pdf"); It's work properly.
after switch to another pdf (eg,def.pdf)file, I try to delete this pdf(abc.pdf) but failed.
the error message is :
the action can't be completed because the file is open in ui Executable.
anybody known how solved it?
Best regards,
feixiang

This problem is already fixed in 3.16 and 3.17.
If you install the newest patches for these version the "old" file is unloaded if a new file is loaded.
