 Each project and component can have its own set of files. To upload a file, navigate to your project or component, then click on files in the grey navigation bar. You can also get to your files page by clicking on the blue widget in your project's project overview page. Now you can simply drag the file from your desktop to a folder. You can also click the upload button in the actions column. The OSF gives each file its own unique URL. You can download files directly from your project or any public project by clicking the download button in the actions column. Privacy of files is determined by the privacy of their project or component. If you upload a file to a component that is set to private, no one will be able to see the enclosed files. In contrast, public components in projects allow anyone to download those materials. When you want to delete a file, simply click the X that appears when you hover over it. Only contributors of the project with writing privileges can add and delete files.
