how do I post a project on plublic key because I made something and how do I put it in my folders

To put it in a folder, go to manage project/files. You can change the active project which will save new files to the selected folder or you can click Copy and move them to the folder. If you only have one file, you don't need a folder. To upload a key, go to Publish/Download. Click Upload. Chose the file or folder you want to upload, confirm it. Now click Publish project.(download to see the key
