I am using a program (mBlock scratch) that has the arduino IDE integrated inside of it. Altogether the installed program is 426 MB and just the installer is 143 MB. I want to reduce the size in any way I can find. I eliminated a lot from the scratch part of the software, and I would like to reduce the arduino IDE also if possible. Here are arduino folders with their size. Any ideas if any of these can be reduced?:
/hardware 177 MB (all necessary?) /java 150 MB (that rt.jar file is huge?) /reference 29 MB (I assume I can delete all .html and .jpg right? /lib 18 MB …
Any ideas on what is safe to strip out of arduino IDE? Note that it is an old Arduino 1.6.5 and that can’t be changed easily as it is integrated with the whole scratch program.
