+// Get the appropriate flag to use for creating files

+// 512kb. This is a fairly low limit, but avoids making
+// things slower in some cases. Since most of what this
+// library is used for is extracting tarballs of many
+// relatively small files in npm packages and the like,
+// it can be a big boost on Windows platforms.
+// Only supported in Node v12.9.0 and above.
