I have Archer C7 v2, so flash space isn't the biggest.
I only have USB 2.0 and NTFS support, SMB and miniDLNA installed, and I have less than 3 MB left.
I previously installed an uninstalled some packages. I might have installed some and forgot to remove them, and I also was thinking hat maybe there are some residual files form uninstalled packages. Is there a way to identify what packages we installed after flashing? Or is there a way to clean orphan files?
Also is it possible to find out what firmware-included packages can be safety uninstalled? What's essential of python packages? I have looked at https://oldwiki.archive.openwrt.org/doc/software/python, but don't wish to uninstall something that could end up breaking things. I don't intend to build my own.
