Using DD for windows to resume a failed file transfer from specific point

By Menelaos Bakopoulos • Tools • 0

If you were transferring a large file and the network cut out you can either restart the copy, or use a tool such as DD for windows to resume from a specific point.
For very large files it is recommended to use better copiers such as robust copy.

I had a file that was 1 421 304 KB in size and I had copied around 60 percent.
Therefore, I needed to start after 852782 KB .

The following command was used:

dd bs=2k if=z:SURCE_FILE of=D:DESTINATION_FILE seek=5767168 skip=426391 --progress

Since skip takes number of blocks defined with size bs= , we skip to 426391.

426391  * 2KB = 852782 KB
