If my LaTeX project is split into multiple tex files, can I edit them all on Overleaf?
For larger projects, it is often preferable not to insert all the code in one main file, but rather to split the contents into multiple files (e.g. chapters of a thesis). The overall project then consists of one main tex file and many sub-files.
These sub-files can be included in such a project on Overleaf by uploading them as attachments (via the files > upload menu in the editor), and referenced in the usual way via \input or \include.
You can then edit these sub-files directly on Overleaf simply by clicking on them
To see a short video demonstrating this, see our blog post on writing your thesis with Overleaf.
