P.s. Please ensure the development board is connected to PC at here (please refers to 2.3.1 for details).
2.3.2.1 Directory
1. Create a workSpace Directory
uPycraft can create a workspace directory on a computer that stores users ' own files and displays them in the directory on the left side of the IDE to help users organize editing files. After Upycraft is updated, the configuration path and internal files in workspace are not lost.
workSpace path is not exist at the first time to open uPyCraft IDE. And when users click workspace, a path selection dialog will pop-up. Users need to select a suitable path to save and click to select a file, and then workSpace directory is available, shown as below.
Click the menu command file→Refulsh Directory to refresh directory after path selection. Here we can see a workSpace dolder and User_lib forlder in the path, shown as below.
If you want to reselect workSpace path, try selecting the menu command Tools→InitConfig and click workSpace directory, shown as below.
2. Create a Device Directory
Right click the mouse to select a directory command device→New Dir, input a directory name (e.g. “mylib”) in the dialog that pops up, click”OK”. Refresh the directory then a new mylib library belongs to device could be seen, shown as below. You can create multiple files in this library and save files of other places to this library.
The previous mentioned that the device files are burnt to boards. Select a file, right-click and a right-mouse menu could be seen. The right-mouse menu can operate the file, shown as below.
- Run: run the file.
- Open: open the file in Code Edit.
- Close: close the file in Code Edit.
- Delete: delete the file (NOTE: the executing file could not be deleted).
- Default Run: run the file in default (run the file when power-on).
- Rename: rename the file.
- New Dir: create a new directory.

6. Drag a File
Drag and Open
A. Internal drag and drop open file: Drag files from the IDE directory to the IDE Code edit box to open the file.
B. External drag and drop open file: Drag files from other places (such as desktop) into the IDE Code edit box to open the file.
Drag and Download
A. Internal drag-and-Drop download file: You can workspace and Upy_lib files in the drag-and-drop way under the device, you can download (the Development Board has been connected).
B. External drag and drop download file: The file on the PC by dragging the way, the file dragged to the bottom of the device (already connected to the Development Board), you can download.
