How do I resize my Linux partition to make it larger
 

I am trying to repartition my current harddrive. I downloaded Simply Mepis 6.0 and went to QTpacked. I was able to locate my drive which now is partition with 15 GB on the first partition and the rest on the extended part. My question is can I make the 15GB larger? If so how do I proceed?

You want to resize without losing any data?

Most liveCD's most noteably Gentoo and SuSe
come with QTparted, which support resizing
Ext2 -3 and reiserFS only
it is best to use a LiveCD since you won't be using the disk your playing with..

First you must resize a logical extended partition (One on the partitions in the second half of your disk.)

Only after you have free space at the beginning of the extended part can you resize it(shrink it).

The increasing of the primary is your last step

GTparted and QTParted are pretty straight forward
