me why would anybody use so much memory for a simple file manager. The answer is simple: the more memory you have, the less memory your OS needs. The less memory your OS needs, the more free memory the CPU has to serve its usual job of handling system requests, running programs, and background services.
I want to use all my available memory for a file manager, but I know that there is a hard limit of 32 GB in total, and on Windows I would have to shrink the boot partition (C) to free up some space. On Linux this is not necessary and should be no problem.
I also know that, on Windows, a registry file can occupy up to a third of the total available space, so I will be eliminating the registry files and files with _.dll_ (32 .Dll files) and _.exe_ (16 .Exe files) extension.
The Linux kernel already takes care of the registry by using the _cifs_ filesystem. If you want to delete something important, just move it to the _.Trash_ directory and delete it from there.
If you installed Xtnsys 18 or you want to try the _.Trash_ functionality, you have to move it to your home directory and add the following line to your _.profile_ file.

We can also use this trick to increase the Linux RAM disk, which is an alternative to the swap partition.
# Add the following lines to the _.profile_ file:
# BASH_ENV=~/bin/bash_history
# . $BASH_ENV
# exit
Finally, there are about 40 other unnecessary files in the _/usr/local_ directory. Some of them are installed with the programs, some are by third-party developers, and some are just leftovers from previous Linux system installations. I don't use them, but I still add some comments for the sake of completion. See Listing 5.3.
