File.hidden doesn't work as expected in Windows 10

G'day all!

First post here, so I'll get right to the point. My script uses Folder.selectDialog, then Folder.getFiles() w/o any arguments.

I follow that up with a loop

if (fileList[0] instanceof Folder || fileList[0].hidden == true){};

File.hidden mentions the "platform-specific file browser" and this loop works perfectly at work on Mac OSX Sierra but fails miserably at home on Windows 10. I've had to add a second means of eliminating files that begin with "._" to clear out normally hidden files that follow photos from the OSX machine.

Is that just a fact of life on a Windows 10 machine with files copied from a Mac?

Thanks in advance!

I checked my code and I also have a check for '._' at the beginning of the file name (file.name.slice(0, 2) == '._'). I only check for the hidden property when I actually have a file to process.

Here's code that I use for determining whether a file is a valid image file.

// Function: winFileSelection
// Description: Determines if a File is an image file (checks file extension)
// Input:  f - File
// Return: true if f is an image file, false if not
//
psx.winFileSelection = function(f) {
  var suffix = f

In Explorer on Win10, open the properties dialog on the File/Folder and see what it says. Finder may be hiding the files because it's a Mac thing.

yeah, i toggled that and am used to seeing them and deleting manually. But it doesn't look like they return true to Folder.hidden even when non-visible.

Thanks!
