# bmaptool
> Create or Copy blockmaps intelligently (and therefore faster than `cp` or `dd`).
> Homepage: <https://source.tizen.org/documentation/reference/bmaptool>.
- Create a blockmap from image file:
`bmaptool create -o {{blockmap.bmap}} {{source.img}}`
- Copy an image file into sdb:
`bmaptool copy --bmap {{blockmap.bmap}} {{source.img}} {{/dev/sdb}}`
- Copy a compressed image file into sdb:
`bmaptool copy --bmap {{blockmap.bmap}} {{source.img.gz}} {{/dev/sdb}}`
- Copy an image file into sdb without using a blockmap:
`bmaptool copy --nobmap {{source.img}} {{/dev/sdb}}`
