Update file
You can update a file by either dragging and dropping a new version onto the folder where the file is located, or by using the Update file dialog.
Note: When using drag and drop to update a file, the new version must have the exact same filename and be of the same file type as the existing one. Otherwise, it will be uploaded as a new file instead of updating the current version.
If you want to update a file using the Update file dialog, follow these steps
Navigate to Files in the main menu.
Go to your file and click the Menu-icon to the right of the file name.
Select the Update file menu option.

The file previewer will open with the details panel visible showing the versions tab.
Click the Upload new file version button.

In the dialog that appears, either drag and drop the new version of the file, or click to browse and select it manually.

Finally, click the Upload button.
