# Split Files

With the **Split files** option, you can divide each file in your project among labelers so they don’t work on the same data. You can also assign specific files to particular labelers.

## Sample case

Let's say we have a file named `100-rows-reviewed.csv` with 100 rows. Our goal is to divide this file equally between 5 labelers.

1. In step 1 of project creation, upload the files.
2. In step 2, preview the files.
3. In step 3, set the task type and the question set.
4. In <mark style="color:blue;">**step 4**</mark>, choose 5 members as the labelers.
   1. If the purpose in this project is **only to speed up** the labeling process and doesn't require the reviewer judgement, set the consensus to 1.
   2. If reviewer judgement is required, set the desired consensus accordingly.
5. Select <mark style="color:blue;">**Advanced**</mark>.
6. In the **Advanced** menu, select the **Split files** checkbox. Then enter the number of parts in the <mark style="color:blue;">**Parts**</mark> field. In this example, we set it to 5. The file will be split into 5 parts, and `- Part 1` through `- Part 5` will be added as suffixes to the file names.
7. Select <mark style="color:blue;">**Distribute files automatically**</mark>. The system will distribute the file parts based on the consensus setting.
   1. In this case, the file parts will be assigned as follows:
      * John Doe will get `100-rows-reviewed.csv - Part 1`
      * Johnson Dominic will get `100-rows-reviewed.csv - Part 2`
      * James Doe will get `100-rows-reviewed.csv - Part 3`
      * Jason Doe will get `100-rows-reviewed.csv - Part 4`
      * Jeremy Doe will get `100-rows-reviewed.csv - Part 5`
   2. They will only see their assigned file parts in the project.

## Additional information

* The **Split files** option is only available during project creation. File parts cannot be split or merged after the project is created.
* Labelers will **only receive** the assigned parts.
* Reviewers will receive all file parts.
* The **Split files** option is available for span labeling, row labeling, and conversational labeling projects.
* The **Distribute files automatically** option is available for span labeling, row labeling, conversational labeling, bounding box labeling, and document labeling projects.
