Failing drag and drop operations

[WhiteChairFromIkea]

Issue

Drag and drop operation from SFTP client file explorer to DC file panel drops kind of GUID file, instead of real file:

see: https://youtu.be/9mAuucn2sRQ

Steps to reproduce

1. Install https://www.bitvise.com/ssh-client-download
2. Login to test.rebex.net:22, login information: demo/password;
3. Drag and drop file from SFTP server to regular explorer ("MS explorer.exe", or "free commander");
4. File transfer is successful, file is created on local drive with correct filename;
5. Repeat step 3 with DC. Something is transfered from SFTP to local PC, but filename is not correct.

Edit 2021-07-05: I Confirm, part below is fixed in nightly (revision 9843 as per comment by alexx2000):
# EDIT: MUCH EASIER STEPS TO REPRODUCE:

1. Go to public ftp with ms explorer.exe: ftp://speedtest.tele2.net/
2. Drag and drop some file from ftp server to explorer and DC. DC fails, explorer OK.

Drop from Explorer fixed (revision 9843).

On my system drag&drop from Bitvise SFTP does not work with Explorer too (file with GUID created instead).

On my system drag&drop from Bitvise SFTP does not work with Explorer too (file with GUID created instead).

By saying "Explorer" do you mean "default MS Windows explorer.exe"? I am sure I didn't have any issues with explorer.exe (working only on windows 10 with latest updates). As can be seen from the video in OP, "GUID" string is replaced to user-friendly filename string after file is finished copying.

More info: there is no issues when drag-dropping from bitvise SSH to freecommander.exe (https://freecommander.com/en/downloads/) or explorer++ (https://github.com/derceg/explorerplusplus). 2nd is an open source project, so maybe parts of drop code can be borrowed from this project..?

Yes, MS Windows Explorer. Drag&drop from Bitvise SFTP does not work with all file managers on my system (Windows 10 21H1 x86_64). As I see Bitvise use some hackish method for drag&drop, it passing file in CF_HDROP clipboard format with GUID file name. So after drop, file with GUID name created and nothing else happen.
