[Mgr. Janusz Chmiel]

Dear developers,
Do You think, that somebody of us would try to develop little 
application, which would be able to convert .vdi virtual harddisk image 
to Theraw image format?
.img My next Question is.
Why it is not possible to change The size of virtual harddisk if it is 
created by using Oracle vmvirtual box GUI?
Thank You very much for Yours answer.
If You know about free procedure for Windows or Linux, which would 
enable me to convert .vdi harddisk to .img raw image format please let 
me know.
With kindness regards.
