please am using Itext to create report but everything goes to the App Data in the drive C:
please can you give me an alternative so that after installing the user can direct where he chooses to save the reports after generating. thanks.

String ch = inv.getText();
String dataFolder = System.getenv("AP­PDATA") + "/Stock reports/" + ch + ".pdf";

try {

Please, use the </> button to insert source codes to the forum. The AppData folder is specified at the start of your code:

String dataFolder = System.getenv("APPDATA") + "/Stock reports/" + ch + ".pdf";

To make the user select a path in Java Swing, use JFileChooser instead:

JFileChooser chooser = new JFileChooser();
chooser.setCurrentDirectory(new java.io.File("."));
chooser.setDialogTitle("Choose the destination path");
chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY); // Only folders
chooser.setAcceptAllFileFilterUsed(false);

if (chooser.showOpenDialog(null) == JFileChooser.APPROVE_OPTION) {
      String dataFolder = chooser.getCurrentDirectory() + ch + ".pdf";;
} else {
      // Show error message here or perform any failure action you want to
}

Also consider switching to JavaFX.

And are you sure that the code generating the PDF file works? If so, try to print what is in the dataFolder variable at the end:

System.out.println(dataFolder);

What does it print? Maybe I forgot to add a slash:

chooser.getCurrentDirectory() + "/" + ch + ".pdf";

Try to print the path as I wrote in the last message and to add the extra slash.
