Combine partitions, also called merge partitions, it means bring 2 partitions together into a larger one. Why people want to combine partition in Windows 2003 Server?

Almost every Server has free space on D: dirve or other data partitions, so the administrators want to combine the partitions with C drive, then there will be free space in C drive again.

Is it possible to combine partitions in Windows 2003 Server

Of course it is possible. It is easy to understand, a partition is a block of the hard disk, there is start and end position on the block, the positions can be saved as parameters on a record on Master Boot Record DBR and Master File Table (MFT). When Operating System access files in a partition, it reads the record and then it knows which block and where the files are stored.

To combine partitions, get rid of the end position of the first partition and the start position of the second, and then update the record on MBR, DBR and MFT, so partitions combined with all files intact.
