Nevertheless it doesn't work for me anyway, putting file:/// also fails to transfer the MP3 to the Skype window (tested on WIndow 7). And it fails also with other apps I've just tested (Foobar, WMP). Which app you tested as working for D&D to the Skype window? EDIT: It seems that files explorers like Total Commander or Windows Explorer can do this. To be found how they do it.

Not only the standard CF_HDROP (15), but also FileName(49158) / FileNameW(49159) and further 8 formats, to find more...

peke 2018-01-01 13:55 developer ~0049466 Last edited: 2018-01-01 21:15	When testing such issues I always use iTunes, AIMP as mediapps and TC, explorer as file managers. I can confirm that they do not have any issues with Skype. NOTE: WMP is not an reference anymore in Win 10 due the outdated and mostly buggy and crashing all the time. Also you can use http://nes.bplaced.net/clipboarder.html a windows 7+ gadget to see content of clipboard

AIMP and iTunes also use only CF_HDROP clipboard format so copy/paste a track from AIMP/iTunes to Skype don't work. Surprisingly D&D (from iTunes/AIMP) works so they probably use another clipboard format when dragging files, but this is harder to reverse engineer. I've played little bit with clipboard formats that Windows Explorer uses and so far I have tried to include/simulate following clipboard formats (in byte exact forms): 15: CF_HDROP 49158: FileName 49159: FileNameW 49405: DropEffectFolderList 49361: Preferred DropEffect but Skype still isn't accepting any of the above formats. Further formats to try are: 49161: DataObject 49305: Shell IDList Array 49746: DataObjectAttributes 49760: DataObjectAttributesRequiringElevation 49360: DropDescription 49387: Shell Object Offsets 49171: Ole Private Data Maybe "49387: Shell Object Offsets" or "49305: Shell IDList Array" could do the trick, but the structures are not documented so it is time consuming to reverse engineer them. Moving target to 4.1.21

Fromm Offline MSGs "Drag and drop works in Most apps, Only thing is that some apps and Browsers default to MOVE instead of COPY. Brief look Found out that it is possible to Set Copy Only: https://developer.mozilla.org/en-US/docs/Web/API/HTML_Drag_and_Drop_API https://ralzohairi.medium.com/how-to-drag-drop-html-elements-and-files-using-javascript-d31d15279369 Not that good to not screw something along trying, but it looks like it is something for 5.0.1 or 5.1 So 99.9% it works as it should, both with single and multiple files. Great work, much much better than 2291 Skype is one of those 0.1% Test results can be easily watched using: Dragging and dropping files (Firefox only): https://jsfiddle.net/9C2EF/ Dragging and dropping files (All browsers): https://jsbin.com/hiqasek/"
