we would recommend to debug the flow and inspect the variable values. Maybe the value of the FileName variable is empty.

Additional we would also recommend to use variable names different to keywords or classnames. In your case File variable name is the same as the class File

Hi,

This error shows length of File.Name is less than 4.
Can you check content of File.Name, for now?

Regards,

Hi @Sri_Vennila check the syntax of substring:

It should be like(provide the start index)
strVar.Substring(0, strVar.Length-4)
