本文整理了Java中org.openide.util.Utilities.toFile()方法的一些代码示例，展示了Utilities.toFile()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Utilities.toFile()方法的具体详情如下：
包路径：org.openide.util.Utilities
类名称：Utilities
方法名：toFile
[英]Converts a URI to a file while being safe for UNC paths. Unlike File#File(URI) UNC URIs with a host field are accepted.
[中]将URI转换为文件，同时确保UNC路径的安全。与文件#文件（URI）不同，可以接受带有主机字段的UNC URI。

private static File normalizeFileOnUnixAlike(File file) {
// On Unix, do not want to traverse symlinks.
// URI.normalize removes ../ and ./ sequences nicely.
file = Utilities.toFile(Utilities.toURI(file).normalize()).getAbsoluteFile();
while (file.getAbsolutePath().startsWith("/../")) { // NOI18N
file = new File(file.getAbsolutePath().substring(3));
}
if (file.getAbsolutePath().equals("/..")) { // NOI18N
// Special treatment.
file = new File("/"); // NOI18N
