How to switch "MOVE" mode and "COPY" mode?

Hi All!

I recently upgraded to WinSCP 3.5.6 from 3.5.0.
And I found all of my Drag'n'Drop actions from WinSCP are switched to "MOVE" mode.
Older version have "Allow move from remote directory" at "Preferences-Environment-Panels-Drag & Drop" but newest version have not.

Which configuration item would switch this back to normal "COPY" mode?

Thanks in advance.

Have you installed drag&drop shell extension? (note that you may have installed it, but it may be turned off in preferences)

1) If you did:
Copy should be a default operation.

2) If you did not:
Default operation is selected by target application. So if you drag to local panel of WinSCP, WinSCP should select copy. If you drag outside of WinSCP to Windows Explorer (desktop, folder, ...), Explorer selects default operation. It usually selects "move".
To force copy, hold down Ctrl key, just as with any other application. You should saw a hint in warning message on first move attempt, did you?

If anything above it not true for you, please let me know, it may be a bug.

I installed the drag&drop shell extension, but in preferences the 'Use shell extension' option is grayed out.

You may need to restart your computer. Does it help?

nope

If you can work with Windows registry, please verify that following keys are present:
And that path (<path>) in InProcServer32 is valid and the DLL is present there.

everything is in there, except "WinSCP Shell Extension" is in HKEY_CLASSES_ROOT\CLSID (in that main 'folder', not any of the sub ones)

I'm not sure what you mean, can you post a registry dump (similar to one I did)?

Also please check that the extension is enabled (in HKEY_CURRENT_USER and/or HKEY_LOCAL_MACHINE):
Also you may turn on logging for the extension and post a log file:
Thanks for your patience. I'm really interested to solve this.

Enable is set to 1 (0x00000001) and I added LogFile to it, but no log file was created, even after I rebooted.

Thanks for your info. What is your version of Windows? Please try to create the registry key as seen in my post. I believe it should help. Please, let me know.

I'm using Win98 SE, and adding that key did help, thanks!
