Importing data from a txt file is not working

Hello All, We have created an import integration interface which is loading data from a txt file to an import table using a bat file which gets created  by itself when we finish the integration interface creation. When we run this batch file then the data from txt file needs to be imported to Biio table . But while running this .bat file its failing saying that the txt file does not exist . The txt file from which we want to load the data exists but still its showing the same error. Kindly  provide your valuable suggestions on this
