Very simple indeed, I should have thought of that first. Thank you Tristan. :-)<br class="">

An alternative approach which doesn't involve modifying ChimeraX (but still requires action in each user account) would be to simply symlink ~/Downloads/ChimeraX to the centralised location.</div>

Hi Tom,
<div class=""><br class="">
</div>
<div class="">This is the use case I had in mind indeed. Model files are small enough that duplication doesn’t matter, but a shared cache for maps could be convenient. I was simply asking in case there was a supported way to achieve this that I had missed in
the documentation, but I can absolutely live with the current default.</div>
<div class=""><br class="">
</div>
<div class="">Thank you for your answer.</div>

<div class="">Hi Guillaume,<br class="">
<br class="">
There is no setting to change the location where ChimeraX caches fetched files. It is always<br class="">
<br class="">
<span class="x_Apple-tab-span" style="white-space: pre;"></span>~/Downloads/ChimeraX<br class="">
<br class="">
On a multi-user workstation is the idea that every person would change the ChimeraX setting to point to a common cache directory? Will people cooperate with that? Each person of course has their own ChimeraX settings. Everyone will also need write access
to that directory. There are no site-wide settings in ChimeraX.<br class="">
<br class="">
You could modify the ChimeraX application file, a file in the distribution (here's the path for Linux)<br class="">
<br class="">
<span class="x_Apple-tab-span" style="white-space: pre;"></span>chimerax/lib/python3.9/site-packages/chimerax/core/fetch.py<br class="">
<br class="">
making<br class="">
<br class="">
<span class="x_Apple-tab-span" style="white-space: pre;"></span>_cache_dirs = ['/usr/local/chimerax_fetch']<br class="">
<br class="">
near the top would I think change to use that directory. Of course each time you install a new ChimeraX it would need such a change, and if individual users install their own ChimeraX version it will use ~/Downloads/ChimeraX.<br class="">

Hello,<br class="">
<br class="">
The documentation for the open command says "Web-fetched data are stored locally in ~/Downloads/ChimeraX/ (where ~ indicates a user's home directory)". Is there a way to change this directory? I couldn’t find one in the settings window, but maybe a command
could do that? (in that case I would simply need to add this command to the startup commands).<br class="">
<br class="">
The use case I have in mind is to share the ChimeraX cache between all accounts on a multi-user workstation (so, relocate the cache at some place like /data/ChimeraX).<br class="">
