If MATLAB had tons of very small files, I'd maybe wonder if it had something to do with a large(ish) block size of the filesystem that the card might be using. Is an SD card going to withstand an acceptable number of read/write cycles to use it long-term in this way? I don't know the answer to this, just thought it might be a useful thing to investigate.Īre you sure your SD card actually has as much space as it is advertising to the OS?

That must be because the installation location is essentially on an external drive, so the writing speed is slower. Reformatting to NTFS seems to have fixed it, although the installation is still taking ages. I'm running Windows 10 Home edition in case that's relevant.ĮDIT: The problem seems to have been the default (exFAT) formatting of the drive. Is there anything I could do to reduce the installation size on the SD-card without having to download the full software package again? I kind of need the extra space on the SD-card for other uses as well besides just storing a buggy installation of MATLAB. The program itself seems to run just fine, at a speed comparable to running it on a laptop that actually has an SSD larger than 32GB as a system drive (like mine does). However, this structuring of the files seems intentional.

To give you an example, there are 2 copies of zlib1.dll in the in and oolbox subfolders respectively. I checked for duplicate files using CCleaner, and the program found huge amounts of very small files that had at least 1 copy of them, but in a different directory. Is this not correct? What could be causing this? I thought that MATLAB + Simulink were supposed to take only a maximum of 15GB of space with all of the modules installed. What baffles me is that after the installation my SD-card now has about 2GB of free space left. This is because my laptop system drive is too small to hold all of the 15GB of MATLAB goodness. The installation took forever, and in order to perform it successfully I had to change the default download directory in the installer script to the microSD-card using the cmd-command: '( location of downloaded MATLAB installer on my system drive)' -downloadFolder 'Target folder on the SD-card'. I installed the version R2015b of Matlab and Simulink + all of the related packages on a 64GB Kingston microSD card on my laptop.
