Hello everyone! The title may not be that clear what I'm trying to do. First of all, I have created multiple paths like this:

F:\MyFolder\1\testfile.txt
F:\MyFolder\2\testfile.txt
F:\MyFolder\3\testfile.txt

You notice that the only thing that changes in the path is the middle. Now my question. Can I use a textbox to determine the numbers 1, 2, 3 so If I for example type a 2 in the textbox and then click a button, the file
F:\MyFolder\2\testfile.txt will be removed. And if I type a 3 the file F:\MyFolder\3\testfile.txt will be removed.
Basically everything in the path stays the same only the second folder changes.

Thank you for your support,

Sure.  You could set up PHP like this:

<?php

if (isset($_POST)) {
    $fileroot = "F:\MyFolder\";
    $filename = "\testfile.txt";
    $filepath = $fileroot . $_POST['fileindex'] . $filename;
    unlink($filepath);
}
echo '<form method="post" action="">';
echo '<label for "fileindex">Index of file to be deleted: <input type="text" name="fileindex" id="fileindex" value="' . $_POST['fileindex'] . '" />';
echo '<input type="submit" name="submit" value="Submit" />';
echo '</form>';
?>

Sorry, forgot to close the <label> tag on line 10:
 
echo '<label for "fileindex">Index of file to be deleted: <input type="text" name="fileindex" id="fileindex" value="' . $_POST['fileindex'] . '" /></label>';

This is the form:

<form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post">
<input type="text" name="filenumber" value="" />
<input type="submit" name="submit" value="Submit" />
</form>

This isthe php code at the top of the same page:

<?php
if isset($_POSR['submit']){
  $number=$_POST['filenumber'];
  $fname="F:\MyFolder\" . $number . "\testfile.txt";
  unlink($fname);
  echo "File deleted."
}
?>
