SD Card Resize on 32gb SD Card Raspberry Pi

Question

I have a 32gb SD card in my Raspberry Pi. I'd like to make use of all the space, please can someone tell me how to resize?

Disk /dev/mmcblk0: 29.7 GiB, 31914983424 bytes, 62333952 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x0004b03e

Device         Boot   Start      End  Sectors  Size Id Type
/dev/mmcblk0p1         8192  4615234  4607043  2.2G  e W95 FAT16 (LBA)
/dev/mmcblk0p2      4615235 30375935 25760701 12.3G  5 Extended
/dev/mmcblk0p5      4620288  4685821    65534   32M 83 Linux
/dev/mmcblk0p6      4685824  5210109   524286  256M  c W95 FAT32 (LBA)
/dev/mmcblk0p7      5210112 30375935 25165824   12G 83 Linux

Your problem seems to be an extended partition which is only using 12.5GB.

It is unclear how you managed to get this, probably by copying a smaller SD Card.

This can be fixed on a Linux computer, it is probably possible to fix it on the Pi itself, but this requires some expertise and involves some risk.

Your best bet is to do a fresh install of Raspberry Pi OS (on a new Card) and copy your data.

It is inadvisable to use NOOBS - this is difficult to maintain, and if you had used Raspberry Pi OS resizing the partition is simple.
