I know that the dot in the beginning makes the file manager assume that it's a hidden file.
My computer is Windows 10 and I have an Android device.
I created a file on my Android device that starts with a period for example:
.test.txt
If I use Samsung File Manager with show hidden files enabled, I'm able see the file. While on Windows, the folder option settings "Show hidden files, folders, and drives" is enabled and the file is not showing up.
I have also tried unchecking the option "Hide protected operating system files" just in case and it still doesn't show.
I have checked to make sure that it is not a conflict with Windows and created the file on Desktop and it's showing up fine and doesn't count as a hidden system file.
Is there a reason that the file doesn't show up via USB or a way to make it show up?
You can try below solution. On run type: cmd (enter) select USB drive: F: (enter) write: attrib -s -h /s /d . (enter and wait)
After loading completes, check for missing USB file again.
