Hi
I tried posting a reply, but can't find it here. Apologies, but I then tried again, but was told it was a dup.
Here it is:
Thank you Stefan.
PDF24 Reader is my default app for pdf files.
the right-click context menu in Windows Explorer, however, contains only a single PDF24 item, which opens the files in File Tools.
The only way I can see to load the files in Reader is to click on them one at a time from within Windows Explorer, or open sequentially from within Reader.
