Drag-drop from Windows Explorer now works, dropping into an Apple mail message or a Pages document. Thanks for that fix.
Dragging from Explorer to Finder moves the file into the folder selected in Finder. CTRL-Drag, while handled as copy in Windows, does not copy the file to the Finder folder but moves it. It is not something I normally do so can't be sure it worked before V19.2
Copying a file in Explorer using CTRL-C or right click Copy allows the file to be pasted in a Word doc in Win 11 or in another folder in Explorer. This does not work going to Mac and using cmd-V to paste into an Apple mail message, Pages document or folder in Finder. The right click menu or Edit menu has Paste greyed out. Share Mac Clipboard is enabled. Using Finder's Edit menu Show Clipboard shows nothing in the Clipboard.
If I right click in explorer and use Copy as path, the path in quote marks is copied to the clipboard and can be pasted in a Pages doc or email.
Copying a file to the clipboard in Finder allows paste in Explorer, copying a jpeg file in Finder allows paste in a Word document. Copying an image in a Word doc allows paste in a Pages doc.
Copying the text from a file name in Explorer (from the edit filename operation) allows that text to be pasted into a Pages doc
So it seems the main issue now is copying a file in Explorer doesn't allow it to be pasted anywhere on the Mac side.
