In Caja's default settings the next zoom increment after 200% is 400%, which is a bit too much for me.
I am trying to find a way to tweak the settings in order to set an intermediate step between those two, i.e. 300%.
I think I have identified the relevant configuration file that needs to be tweaked for that purpose, but due to my limited skills I am not sure how to tweak it.
Can someone help me?
rather than the actual zoom percentages, which means those percentages are defined elsewhere. dconf-editor just shows the nicknames above for the caja zoom levels

Yes, I had noticed that, but I was not able to find out where those values are defined.

They appear to be hard-coded in the source code. The actual icon size values equating to the various zoom levels are defined in libcaja-private/caja-icon-info.h:
Code:
/* Nominal icon sizes for each Caja zoom level.
* This scheme assumes that icons are designed to
* fit in a square space, though each image needn't
* be square. Since individual icons can be stretched,
* each icon is not constrained to this nominal size.
*/
#define CAJA_ICON_SIZE_SMALLEST 16
#define CAJA_ICON_SIZE_SMALLER 24
#define CAJA_ICON_SIZE_SMALL 32
#define CAJA_ICON_SIZE_STANDARD 48
#define CAJA_ICON_SIZE_LARGE 72
#define CAJA_ICON_SIZE_LARGER 96
#define CAJA_ICON_SIZE_LARGEST 192

Thanks for taking the time to look into this, I appreciate.
Too bad those settings are hard-coded, because I really need to have an intermediate zoom setting between 200% and 400%. The gap is too much.
I have a couple of related questions:
1) if I decide to modify the source and then recompile the whole thing, will it be enough to remove Caja and then download the program's master branch from Github and use make? I am not a professional programmer, so I was wondering if perhaps there is something else to do that I do not know.
2) how long approximately will compiling Caja take, minutes or hours? (my CPU is intel i7 8th gen)
I'm certainly not an expert on this, Grabby, but rather than potentially muck up your system, I would suggest setting up a virtual machine or a dual boot so that you can use a test system for playing around with Caja. If you are going to play around with your main system, I recommend making a system snapshot/backup/image first.
First things first. I suggest creating an issue about the zoom settings here - https://github.com/mate-desktop/caja/issues. Sometimes it takes a while for someone to respond, but the developers tend to look at the issue reports so it's a good place for your issue to be noticed.
Then, depending on the answers you receive, you can look at hacking Caja. If you do, I would suggest you download the latest released version rather than the latest code - see http://pub.mate-desktop.org/releases/1.21/
I don't think it would take you long at all to build Caja. Replacing your current version of an integral component of the desktop with a new one compiled at your own hand may prove interesting though.

you can always try to 'make' (as normal user, not as root) without actually installing it.
the executable usually gets dropped in some subfolder.
you can try running it from there.
if you're lucky it will Just Work, and you are not endangering any system files.
no idea how long the compile will take; getting all the dependencies right, dev versions of libraries on debian-based distros, etc., will probably take longer than the actual compilation.
@ondoho: I followed your suggestion and after modifying the source I compiled it as non-root. Compilation went OK. The executable file was created in the ./src subdirectory, and it runs. Only, for some strange reason the version of Caja that runs is not the one I compiled (version 1.21.3, as displayed by the autogen.sh file) but the one previously on the system (version 1.20.3). I could tell by looking at the About dialog.
Of course I used the ./ before the filename of the executable, and yet the program loaded is the default one that was already present on the system.
I even tried changing the name of the executable to avoid any possible name conflict and I ran it again, so there is no doubt that the program loaded is the one I compiled -- once again, the program runs fine, but it is not the version I compiled.
Any idea how to make sure that the program loaded is the one in the current directory?
It just came to my mind that since Caja is always running in the background (because it manages the desktop icons) there may be a problem with loading into memory another version of it, so I am redirected to the Caja that is the default on the system. Could this be the reason?
while pidof caja; do killall caja; sleep 1; done; ./caja
(this should exit after 1s and start your custom caja; if not caja is automatically respawning itself).
but even if you manage to kill the caja process for goosd, it's probably still calling upon system resources, sth like /lib/caja/version.gui maybe... the answer to that lies in the sources and possibly in the compilation options.

Caja is respawning itself, as you predicted, in an endless loop. I think it's time to give up on this. I will probably keep the binary and try to run it in another desktop environment when I have a chance.
