I have just upgraded a TP-LINK TL-WDR4300 to the latest version of OpenWrt and have managed to fill up most of the available space. How do I identify programs/drivers that I can do without? I tried installing Midnight Commander but ran out of space, after most of the components had been installed.…

[image] balanga: TL-WDR4300 this device only has 8MB flash memory. If you're running out of space, you may need to look at doing an extroot (using a USB thumb drive in one of your USB ports) to give you more working space.

The best way to recover is to run firstboot (or GUI reset to defaults) or flash again, and start over. Trying to selectively delete stuff tends to leave a lot of residual files. Adding support for smartphone tether is only a few kmods that will not take much space.

building on another aspect of deleting stuff... Don't try to delete the packages that are built into the image you flashed. That will, counterintuitively, actually consume space and it will not free anything up. If you want to remove packages that you won't be using, build a custom image to save sp…

I don't think this applies to the OP with ath79 21.02.1, but if you're running snapshot builds, the attended-sysupgrade will automatically squash up a new ROM with your desired package configuration, including removing standard built-in packages that you don't want. Add or remove packages, then requ…

If I flash again will all the packages I've installed disappear? I'll try anyway - nothing to lose...

[image] balanga: If I flash again will all the packages I've installed disappear? Yes that is the point, so you can be more selective which ones to install considering the limited space.

Should I use 'df' to see how much space I have? And how do I tell how much space 'mc' uses? Some distributions do an mc-light. Is this available for OpenWrt?

[image] balanga: Should I use 'df' to see how much space I have? What happens if you just do it instead of asking?

df -h tells me I have 2.5M available on overlayfs:/overlay and 60.2M on tmpfs but I don't how to find the size of the mc package.
