How to find out when file was created in ColdFusion

Question

I have found a function which returns file info: GetFileInfo()

It returns following data:

• Name: name of the file
• Path: absolute path of the file
• Parent: path to the file’s parent directory
• Type: either "directory" or "file"
• Size: file size in bytes
• Lastmodified: datetime when it was the file was most recently modified
• canRead: whether the file can be rea
• canWrite: whether the file has write permission
• isHidden: whether the file is a hidden

But this data does not show when the file was actually created. How to find it out?

(From comments ...)

It was probably omitted because it is o/s level metadata. Assuming creation date is supported on your o/s, try using java.nio:

<cfscript>
   physicalPath = "c:/path/to/someFile.ext";

   // Get file attributes using NIO
   nioPath = createObject("java", "java.nio.file.Paths").get( physicalPath, [] );
   nioAttributes = createObject("java", "java.nio.file.attribute.BasicFileAttributes");
   nioFiles = createObject("java", "java.nio.file.Files");
   fileAttr = nioFiles.readAttributes(nioPath, nioAttributes.getClass(), []);

   // Display NIO results as date objects
   writeOutput("<br> creation (date): "& parseDateTime(fileAttr.creationTime()));
   writeOutput("<br> modified (date): "& parseDateTime(fileAttr.lastModifiedTime()));

   // Display CF results for comparison
   fileInfo = getFileInfo(physicalPath);
   writeDump(fileInfo);
</cfscript>
