Hi @Kumaresan K ,
Welcome to Microsoft Q&A forum and thanks for reaching out.
Unfortunately there is no out of box ADF connector to copy files directly from OneDrive.
As a workaround you may give a try exploring ADF HTTP or REST connector to call OneDrive REST API available in Microsoft Graph API. and see if that helps.
The implementation can be similar to this process - Copy file from SharePoint Online
If you have any feedback regarding feature request for this requirement, I would suggest you to please share it in ADF user voice forum - https://feedback.azure.com/forums/270578-data-factory.
All the feedback shared in this forum are actively monitored and reviewed by ADF engineering team. Also please do share the feedback link here once it is posted.
Hope this info helps.
