How to show .Trash and hidden files on USB sticks but not in $HOME?

Question

In my home directory, there is a lot of files beginning with a dot, and I like the fact that Nautilus hides them. But when Nautilus hides .Trash on a USB disk, I risk leaking confidential documents inadvertently, wrongly thinking that I deleted all files from the USB stick I give to an acquaintance.

So, how to set Nautilus to:

• Hide these files in my home
• But show them for USB sticks?

Another solution could be to disable Trash for USB sticks, but the idea is not implemented yet.
Any alternative solution welcome. I am looking for a permanent solution, so hitting CTRL+H each time is not a solution.

Solution

Nautilus doesn't support automatically changing settings based on the directory. You can use Ctrl+H to manually toggle between showing or not showing hidden files (usually known as dotfiles), but Nautilus can't be configured to automatically toggle that option.

However, if you're using a filesystem on your flash drive that supports symlinks (not FAT32 or NTFS), you could work around your issue this way:

cd /path/to/your/flash/drive
ln -s .Trash Trash

This way, you'll have a non-hidden directory where you can easily check the contents of your trash.

Unfortunately the link trick is not usable, because the majority of USB sticks tends to be configured as FAT32 (especially those people lend to each other).

You're unfortunately correct. My flash drives must be usable on Windows machines. Grr.

Actually, I've heard that NTFS has something like symlinks. I haven't researched it, but perhaps you could reformat your flash drive as NTFS and use that trick. These days, NTFS is supported across all platforms.
