@jajodiaraghav, Sorry I was busy with some other work. I understand that the zip file will contain all the PNGs and SVGs. But when a user uploads another CSV file, the older data and CSV file is also there. So all-badges.pdf will contain images from both CSV files. So the zip should contain all the images generated till now? What about the second and third point? SVG and PNG of the latest files uploaded and should it be zipped or individual?

The zip file will contain:

1. all-badges.pdf
2. Individual pdf files generated
3. Individual svg files generated

But when a user uploads another CSV file, the older data and CSV file is also there.

The older data will be removed before uploading new files. Do not worry about them.
