-v (Create Volumes) switch

Specifies volume sizes.

Syntax

-v{Size}[b | k | m | g]

{Size}[b | k | m | g]
Specifies volume size in Bytes, Kilobytes (1 Kilobyte = 1024 bytes), Megabytes (1 Megabyte = 1024 Kilobytes) or Gigabytes (1 Gigabyte = 1024 Megabytes). if you specify only {Size}, 7-zip will treat it as bytes.

It's possible to specify several -v switches.

NOTE: Please don't use volumes (and don't copy volumes) before finishing archiving. 7-Zip can change any volume (including first volume) at the end of archiving operation.

Examples

7z a a.7z *.txt -v10k -v15k -v2m

creates multivolume a.7z archive. First volume will be 10 KB, second will be 15 KB, and all others will be 2 MB.

Commands that can be used with this switch

a (Add),
