SAFBuilder file being used 0 times

[Sameer786]

I have created a CSV file to be imported into Dspace and placed it into the same folder where the actual pdfs are stored.
But when i run the SAFBuilder . it gives files were used 0 times for the all the files in CSV . files with the same names are stored in the directory where the CSV file is placed.
i have used the following command
./safbuilder.sh -c /home/shailendra/UploadDec21/Dataforupload/Dataentrynew.csv -z
Dataentrynew.csv
above CSV file i am using for upload.
can you please highlight where exactly i am doing wrong.
