How large is your "hidden" Arduino folder

BigG
BigG 4 months ago

I've been doing a different sort of spring cleaning this weekend.

As my disk drive is almost full, I ran the Linux disk usage analyser tool on my Home folder and revealed, unsurprisingly, that the .arduino15 folder was the main culprit (being the "brains" behind it all). This was due to the staging folder, which was well over 15GB!

It turns out that the contents of this literal "staging" folder is really just a type of cache should you want to reinstall stuff again. It appears there is no automated means of cleaning.

So, if you haven't touched yours what size has yours grown too - it's indicative of how extensive you use it (bragging rights, I suppose :-D).

What other tricks do you use to automate disk usage spring cleaning.

    That's me alright. Probably should be attending "Arduinoics Anonymous" with all the boards I've got set up. Yeah, that's a good point. It may well be a result of me clutching onto 1.8.16 for so long. Only…

    Sounds like a job for a directory junction.

    Hi  BigG 

    Well actually my Arduino15 folder uses about 4,5 GB space. The subfolders under staging are libraries (138MB) and packages (807MB), which have the most contents.

    Under Arduino15 the IDE stores all downloaded installation files as well the IDE using remote sketchbooks, cloud build projects (connected to Arduino project website), etc....

    Then you have the Arduino ide update folder, which contains the IDE installation files.

    Under the user-document folders you have your own Arduino project folders, which also explode by project to project.

    And in the user temp folder you have the opened projects which will not closed and not deleted automatically after closing the IDE.

    ---....---- and so on...

    That's a great analysis. Thanks. I think the irony of it all is that the more frequent you keep boards and libraries updated the worse it gets.

    I found in my case that the big staging library folder hoggers were Adafruit and lvgl libs as they have quite frequent updates, and then with packages it seemed to be esp32 and the Arduino giga board files.
