How to use project's folder without using hard code?

Hi

You can mention the relative path which means you don’t need to put the complete filepath

Just mention the folder name alone and following folder name or file name directly in your workflow

It will work
Have a view on this thread to know about absolute filepath and relative filepath

If you want to call workflow from the folders you created then u can use INVOKE WORKFLOW ACTIVITY and click on the folder button to call them
