# Sharing files across projects

You may share files across projects using the **From Another Project** option located within the **Add Files** pop-up window:

If you'd like to (regularly) use the same files across multiple projects then it may be convenient to use the following arrangement:

1. Create a “parent” project containing your reusable files, e.g., `.bib`, `.cls`, `.sty`, graphics, etc.
2. Within a “child” project, in which you want to reuse a file, follow this procedure:

* Click the **Upload files** button at the top of the file list panel, or go to the **File menu** and select **Upload file**. Overleaf displays the **Add Files** pop-up window. Here, you need to do the following:
  * Select **From Another Project.**
  * Under **Select a Project**, choose the “parent” project containing the reusable files.
  * Under **Select a File**, choose the file that you need.

You will now be able to *use* the linked file within your “child” project, but you will *not be able to edit it*. Although linked files in “child” projects cannot be edited, they can be updated (refreshed) if you’ve modified the original copy of the file(s) in the parent project:

* Click on the linked file in the “child” project.
* Select **Refresh** to pull in the changes.

{% hint style="info" %}
Any `.tex` files imported using **From Another Project** cannot be set as the main file for compiling the “child” project.
{% endhint %}
