Hi @NurHossain-4331,

From your description, the question is about the system file under System volume information folder, which is more related to the Windows server. So I'll help add a Windows server tag.

Hi,

Please chekc if you have enabled Volume Shadow Copy on the drive and set no limit on the shadow copies. If so, each new VSS snapshot is stored in System Volume Information folder. The more often the shadow copies are created and data on the disk are changed, the faster the size of this folder grows.

If you want to remove the files inside the folder, you can disable the Volume Shadow Copies. If you want keep the VSS, you may set the limit the volume shadow copy in size.

Steps:
Right click the drive > Select Configure Shadow Copies > Disable or click Settings > Check Use limit and set the maximun size

If you haven't enabled Volume Shadow copy, please check if you installed third-party Symantec backup software. It will create temporary files in the System Volume Information folder, which cause System Volume Information folder is growing and may take up the available disk space.

Those look like DPM files, not related to Exchange.
I would ask in the DPM forums:
