Open Source Document Management System | OpenKM

I am using OpenKM on Windows Server 2003 R2 and planning to expand HDD as it is going out of space. I have C: , D:, E:, and F: on my system and OpenKM is installed in C: so if I expand the HDD then will it be problem for OpenKM to run. I want to expand C: as it is used by OpenKM and there won't be any space soon.

First of all do a backup.

Second, it should not be a problem. However take in mind you also can change repository destination folder. This is also a good option for a huge repository.
