how to format usb drive without losing data

Windows do not allow internal partitions to be formatted in ExFat by default so we need to follow Disk Part approach! However, I am also giving following solution for someone who may want to format the internal partition to exFat.

Here you have two solutions! One to simply format using the right clicking on partition and click on format which will work on external hard drives only. What I did, is left my laptop for hours to get this done! Caution: Portables are not supposed to run for hours.

When you are done with creating another partition, move the data to the new partition, which is pretty time consuming I get that. Enter the size that is enough to copy all the data, then continue. To shrink the partition, click a partition that you want to shrink, and click on Shrink. What you can do is, Shrink the partition in your Portable, using Windows management tools (right click 'computer' and goto Management, then goto 'Disk Management'). Since I was also looking for this solution and found nothing really working! I did a workaround. Assuming you are using Microsoft Windows, I have an idea for you.
