We simply call DoDragDrop passing the files to be dragged wrapped in a DataObject. To start a drag operation into Explorer, we implement the ItemDrag event from the Listview, which gets called after you drag an item more than a few pixels. The sample is fairly self explanatory, I’ve tried to cut out any code that wasn’t showing stuff that was relevant. I found a couple of examples on MSDN for drag and drop, but not using files, but they were still useful ( Performing Drag-and-Drop Operations and Control.DoDragDrop Method).Īlso, there was a snippet for doing cut & paste, which was useful: How to Cut Files to the Clipboard Programmatically in C#? Using the code So, I implemented a simple file watcher to watch the displayed folder and refresh it if it changes. I discovered that it is not possible to receive notifications when someone pastes your files into another folder (thereby cutting them out of the folder you are displaying) to allow you to update the view. ![]() You can also use the right click options for cut and paste. You can also drag from Explorer into the sample, and you can use the Shift and Ctrl keys to modify the action, just like in Explorer. This sample project lists a folder full of files, and lets you drag and drop them into Explorer. The operation is fast and a history list of downloaded data is available, allowing easy access to any of them.Recently, I needed to implement drag and drop with the Windows Explorer, but all of the examples I could find were not quite what I wanted. Conclusionįiledrop is one of the simplest solutions for transferring files between different devices in the local network. Initiating a transfer from any device is an effortless action that requires you to drag and drop the data in the application window.Īfter the receiver accepts the incoming transfer its progress is shown in percentage and the list of files allows easy browsing through all the data received.įiledrop can be used with any computer hooked to the local area network and discovering the peers is a quick process that is carried out almost instantly. However, it also offers brief configuration options that consist in defining a different download folder and emptying the list of downloaded items. The interface is minimalist and at a first glance it just shows the available devices by displaying the desktop background image and the name of the device. If the product is launched on both devices it should signal their availability after a brief scanning. Looks are not what the developer focused on as functionality of the product is more important than aesthetics. ![]() There aren’t any attempts to push third party software on the system. The desktop application needs to be installed and the entire process is extremely simple as it just requires you to follow the instructions on the screen. It aims at making file transfer easier between a mobile device and a computer and vice-versa. Filedrop has been created to facilitate file sharing between devices on the same network. ![]()
