Hello Puneet,
You can try using the 'File Exists' action of the 'Utility - File Management' VBO.
Before that you will need to format the name of the file as per today's date.
"ABC_"
Concatenate the above text with formatting to today's date in DDMMYYYY format so that the resultant file name string will be ABC_04032018
If the file exists then you can proceed further on what you need to do with that file.
