My basic disk is partitioned into one primary partition ((C:) "OS", system partition) and one extended partition (containing two logical drives, (D:) "Programs" and (E:) "Data Files"). Unfortunately, when I did this several years ago, 20GB seemed like plenty of space for the OS/system partition. Now however, despite my best efforts to keep everything except OS-specific items off of that partition, I am out of space on (C:). (C:) has below 1GB of free space, and I am about out of tricks to "create" new space (e.g., deleting Temp and uninstall files, reducing size of Recycle Bin, disabling Hibernation, moving Page File, etc.). And when I had created the extended partition, I used the maximum available space, so there is no available unallocated space I can add to (C:). So my question is, how can I resize (reduce) the extended partition (that is fully occupied by (D:) and (E:), each of which has plenty of free space) to free up some unallocated space that I can then add to my system partition (C:)? A screen shot of my situation from the MMC Disk Management snap-in is posted here. Thanks in advance for any help.1 person got this answerI do too

I know the reply is very late. Found your question looking for a problem of my own.Use a partition movement and resizing tool. Some examples are the disk management tools that come from your drive manufacturer. Seagate and Western Digital are repackaging versions of an Acronis tool. I know they have partition copy, move/resize may be there too. You could also use EASEUS's Partition tool. There's a free version for XP. I've used a higher, paid version for all OS's. It works, I trust it.For your tasks:Defrag D and E, repeatedly to consolidate free space. Shrink volume containing E toward the end of the disk, choosing to leave free space before the E volumeShrink and move D toward E, leaving no space between volume E and D. If not already done, shrink the extended partition containing logical drives D and E, toward the end of the disk, leaving the total free space before D, and after C equalling the amount you want to increase C.Extend the primary partition containing drive C into the unallocated space between C's partition and the extended partition containing logical drives D and E.If this helps, cool. If you already have it figured out, better.
