# How to send files to Similarity Check? Nestor can send files to Similarity Check (SC). SC can be triggered either manually or automatically. --- ##### Automatic Similarity Check Automatic SC is defined at the [file type](https://doc.nestor-edp.org/books/editorial-office-guide/page/configuration-of-file-types) level. The conditions are the following: - the auto SC box type must be checked in the file type - this is the first version of the article - the file is either DOC or PDF - the file must not exceed 20 MB If all these conditions are met, the file is automatically sent to SC when the author completes the submission. This will return a similarity percentage that you can retrieve in the file module: [![image.png](https://doc.nestor-edp.org/uploads/images/gallery/2023-05/scaled-1680-/nmrfKZ5KCWhUMgQT-image.png)](https://doc.nestor-edp.org/uploads/images/gallery/2023-05/nmrfKZ5KCWhUMgQT-image.png) ##### --- ##### Manual Similarity Check On an article, in the [file management module](https://doc.nestor-edp.org/books/editor-guide/page/the-file-management-module/edit), the SC button will appear if the following conditions are met: - your [profile ](https://doc.nestor-edp.org/books/editorial-office-guide/page/editor-profile-decisions-and-proposals)must have the right to use SC - the file is either DOC or PDF - the file must not exceed 20 MB [![Capture3.PNG](https://doc.nestor-edp.org/uploads/images/gallery/2023-05/scaled-1680-/2cu83q2TPvIkFFUV-capture3.PNG)](https://doc.nestor-edp.org/uploads/images/gallery/2023-05/2cu83q2TPvIkFFUV-capture3.PNG) Push the button, and let simmer a few minutes… --- [![Screenshot 2023-05-05 at 15-23-43 EDP NESTOR Editor dashboard.png](https://doc.nestor-edp.org/uploads/images/gallery/2023-05/scaled-1680-/JUlwujAfZqmvHYE4-screenshot-2023-05-05-at-15-23-43-edp-nestor-editor-dashboard.png)](https://doc.nestor-edp.org/uploads/images/gallery/2023-05/JUlwujAfZqmvHYE4-screenshot-2023-05-05-at-15-23-43-edp-nestor-editor-dashboard.png) Nestor will then display the similarity result, clicking the percentage will lead you to the full report in iThenticate. --- [![image.png](https://doc.nestor-edp.org/uploads/images/gallery/2023-05/scaled-1680-/nmrfKZ5KCWhUMgQT-image.png)](https://doc.nestor-edp.org/uploads/images/gallery/2023-05/nmrfKZ5KCWhUMgQT-image.png) --- [![image.png](https://doc.nestor-edp.org/uploads/images/gallery/2023-02/scaled-1680-/C0zLuJ9AN6Yk0fwp-image.png)](https://doc.nestor-edp.org/uploads/images/gallery/2023-02/C0zLuJ9AN6Yk0fwp-image.png)
