Jump to: navigation, search

This page is meant to help you with easy partitioning the SD card to create:

  • ext2 partition (for android app2sd and other tricks)
  • swap partition (for android swap creation)


ROM Manager and some recoveries, eg ClockworkMod_Recovery or 4EXT, can partition SD cards.


using MiniTool Partition Wizard Home Edition

Simplest way is to use "MiniTool Partition Wizard Home Edition" from

This tool is compatible with Windows 2000/XP/Vista & Windows 7

requirements: USB SD Card reader.

pull SD card from phone, insert into USB SD Card reader. Windows should report new drive and content of the drive should be visible.

  • step 1: delete old partitions on SD card

Note: this partition manager QUEUES the operations. So nothing is deleted and changed UNTIL you click "APPLY" and then confirm by clicking "OK".


Make sure you are deleting partition on SD card! (not your hard drive for example)

This step deletes everything on SD card, so backup files first!

Dont be afraid, just read everything and think twice before selecting correct drive.

Do you see three gray icons on the bottom? Under each of them the capacity of each drive is listed, and SD CARD has slightly different icon.

Hard drives on the screenshot have 465.8GB and 74.5GB, and on the bottom, the SD card, with 3.8GB capacity.

  • step 3: create ext2 or ext3 or swap partition*

select "Create As": PRIMARY

Select "File System:" ext2 - for App2SD


Select "File System:" swap to make swap :)

If you want to create both: do not assign all the space for the first one :) this way you will have space for creating second one.

  • step 4: finish

finally, click "apply" button on top left corner.

partitions will be created and card will be formatted.


As of January 2016 Minitool does not know 'exFAT' but the existing Windows tools can be used to write an exFAT partition & any other partitions can be written with Minitool.

exFAT (specified for SDXC) partition type is '0x07' the same as ntfs & can be formatted by built-in Windows tools
