Out of root partition space

[Sarah Johnson <sarah-johnson-1990@list.ru>]

Hi,
I ran out of root partition disk space and can't install or remove any more packages or even login gui window manager anymore

i spent few good hours researching for solutions and found that i can resize root and home partitions using resize2fs and lvresize tools but they are not even installed on my system

so is it safe to resize debian root and other partitions using windows machine partitioning tool ?
knowing that my debian installation is on a USB stick

Thanks
