Alternative to Nautilus for copying file paths?

Copy from nautilus and then paste into a terminal by right-mouse "Paste as Filenames". This will preserve the path. This menu option appears only after copy. I have tested this on fresh installs of 19.10 and 20.04.

For files paths copying/pasting you could use Caja or Thunar:

sudo apt install thunar caja

Other answers introduced various file managers, but I went for Nemo because it is pretty much similar to Nautilus. Contrary to what I had read, Nemo 4.4.2 pastes the file location with no superfluous text.

Nautilus is indeed the worst thing I encountered in Ubuntu. And I faced a series of problems with it.

In a fresh installation of 20.04, I constantly get the error of

nautilus[3111]: Called "net usershare info" but it failed: Failed to execute child process “net” (No such file or directory)

apparently, because I do not have net command installed, and Nautilus does not understand it.

tracker-miner-fs constantly works because I have over 10 HDD archives connected to my computer, and it indexes the files I do not want to be indexed.

I went through a complicated process to effectively disable it.

The worse thing is that you cannot uninstall it without breaking the system.
