I would like advice please on how to conveniently use the latest PTE AV 10 for new projects whilst keeping my many older projects on PTE 9.
I have defined a new file extension ".pte10" and specified (to Windows 10) that files with that extension are to be opened with the latest PTE AV 10.
The standard extension ".pte" opens existing older files with PTE version 9.
Just one problem so far ... "Save As" with the pte10 extension does not save the slide list.
Any ideas please?
