# OneDrive - Upload large file using session action (file)
The Upload large file using session action uploads a large file to Microsoft OneDrive using a file session. There is no fixed file size limit. The maximum size depends on whether the upload completes within the job timeout limit.
# Input
| Input fields | Description |
|---|---|
| Folder | Select the folder where you plan to upload files. Enter the file path where you plan to add the new file. For example, folder-one/folder-two. |
| File name | Provide the file name with its extension, such as New-csv-file.csv. If a file with the same name exists, the action overwrites it. |
| File size | Enter the size of the file in bytes. |
| File contents in text or binary format | Provide the content of the file in text or binary format. |
| Chunk size | Configure the chunk size to optimize throughput. A larger chunk size increases throughput but risks hitting API limits. The value entered is multiplied by 320 KB. The default is 5 (1600 KB). |
