Delete files with filenames longer than x

I am looking for some help creating a BAT file to help delete videos and images over a certain filename length.

A bit of background:

We have a custom made application and we do not have the source code. it updates its videos from a feed. recently we have been getting "buffer overrun detected" errors. we believe that the file names longer than 90 characters are becoming an issue.

I would like to remove these WMV and JPG files before they become a problem. We usually use bat files to perform these small tasks.

Don't stick to something OS -specific, use scripting language that would run on any platform, e.g. Node.js

var fs = require("fs");

var folderName = __dirname;  // for current folder
var maxlength = 90;

function getFiles(dir, files_) {
    files_ = files_ || [];
    var files = fs.readdirSync(dir);
    for ( var i in files) {
        var name = dir + '/' + files[i];
        if (fs.statSync(name).isDirectory()) {
            getFiles(name, files_);
        } else {
            files_.push(name);
        }
    }
    return files_;
}

var files = getFiles(folderName);
console.log(files);
for (var i = 0; i < files.length; i++) {
    filename = files[i];
    if (filename.length > maxlength) {
        console.log("Deleting " + filename);
        fs.unlinkSync(filename);
    }
}
