    ❓ How can I edit a file using Source Code Editor?

    First of all, you need to upload a file from your local device to the Source Code Editor. This can be done in the two ways: drag and drop your file to the white area with the label ”Click or drop your file here” or click on this area and then select the desired file using file explorer. Once a file is added, the green progress bar will begin to grow, and when completed, the Source Code Editor will be opened with file content inside it.

    📶 Does Source Code Editor require an internet connection when a source code is loaded and opened?

    Yes and no, depending on what you’re doing. In general, the Source Code Editor is a client-server web application where there is a client-based part and a server-based part, which are communicating between each other. But in the client-side a lot of operations are implemented with JavaScript and doesn’t require connection to the server. Once a document is loaded and opened, you can view and edit a source code without any limitations: this includes adjusting the presentation of a code content, export to HTML markup, search, redo/undo and so on. But for saving, downloading original or edited versions of a source code the internet connection is required.

    🛡️ What about privacy in the Source Code Editor, is it safe?

    Yes, Source Code Editor is safe because its usage scenario implies that you select and open a file with source code, edit it and then save and download the edited version, and that’s all. Once you upload a file, a unique URL is generated, which is associated exactly with this single file. No one else except you knows this URL, so 3rd person can see the file only when you share this URL with him. Finally, we do not store user files on our servers indefinitely, — every uploaded file is automatically deleted from our servers 24 hours after uploading and the URL will become inactive and is NOT recycled for the consequent uploaded files.
