1.6.2: File can't be loaded! warning when open files on external drive [MacOSX]

1.6.2: File can't be loaed!

XnView: MP 1.6.2 - 64-bit
OS: MacOSX - 64-bit

XnView shows me "File can't be loaded!" when opening files - newly created files on an external disc or copied files to the external disc. After disconnecting the drive and connecting the drive again there is no problem with open these files.

I can save and open or copy and open files with other programs eg. Photoshop, Lightroom, Apollo One, etc. - the problem is only on XnView.

Effect: When I try to open the file, XnView shows me the bug "File can't be loaded!" and on the top I can see "empty" instead of the file's name.

do you have only this problem with new file added to your external drive?

[cath]

Yes.

[xnview]

Yes.

files are added by XnView or Finder?

[cath]

By Finder, by Lightroom CC and by Photoshop CC.

If I copy a file by Finder from my external drive and paste it to my external drive - XnView opens it.
If I copy a file by Finder from another place, eg. my internal drive and paste it to my external drive - XnView can't open it ("File can't be loaded!").

If I copy a file by XnView from my external drive and paste it to my external drive - XnView opens it.
If I copy a file by XnView from another place, eg. my internal drive and paste it to my external drive - XnView opens it. XnView opens it on XnView program (as photo viewer, from folders) and on Finder (when I click on the file normally).

Crazy.
