$fs = get_file_storage();

foreach(file("filedump.txt") as $filepath) {

    $fieldlist = explode(',', $filepath);
    // echo $fieldlist[0];  // id
    // echo $fieldlist[1];  // contenthash
    // echo $fieldlist[2];  // pathnamehash
    // $fieldlist[3] = $context->$fieldlist[3];  // contextid ???
    // echo $fieldlist[4];  // component
    // echo $fieldlist[5];  // filearea
    // echo $fieldlist[6];  // itemid
    // echo $fieldlist[7];  // filepath
    // echo $fieldlist[8];  // filename
    // 'contextid' => $context->id, // ID of context
    // Get file
    // $file = $fs->get_file($fileinfo['contextid'], $fileinfo['component'], $fileinfo['filearea'], $fileinfo['itemid'], $fileinfo['filepath'], $fileinfo['filename']);
    $file = $fs->get_file($fieldlist[3], $fieldlist[4], $fieldlist[5], $fieldlist[6], $fieldlist[7], $fieldlist[8]);

    // Delete it if it exists
    if ($file) {
        echo "Found";
        $file->delete();
    }
    else {
        echo "Not found";
    }
}

Sorry, I have to leave some debugging lines in the source. I think, my current problem is how to get the context from the context id. (See the ??? mid right.) If I uncomment that line I get:

PHP Notice:  Undefined variable: context in /var/www/html/bztfdevmoodle/delfiledump.php on line 22
PHP Notice:  Array to string conversion in /var/www/html/bztfdevmoodle/delfiledump.php on line 22
PHP Notice:  Trying to get property 'Array' of non-object in /var/www/html/bztfdevmoodle/delfiledump.php on line 22
PHP Notice:  Trying to access array offset on value of type null in /var/www/html/bztfdevmoodle/delfiledump.php on line 22

The cause must be obvious to the developers, who master Moodle's "context".
