Best format for disk management

[paissj]

I need some advice as to how to best set up by disk drives.  Disk 0 contains my operating system but is very small (119.23gb) and disk 1 contains recovery but is large (931.50gb) and contains alot of unallocated space.  I dont know why I have 2 disks and would prefer to merge or best utlise the space I have.  Please see image of disk management for my PC:

First off, you can not merge the space across two physical drives.

Second, the first "drive" contains the OS and boot files because it is a fast SSD.  The second contains other stuff, including another 980MB partition, because it is much larger.

You also can't merge the unallocated space with the first partition on the second drive because of the 980MB partition between them -- at present.  If you download and install a partitioning tool, you would be able to move that 980 partition to the right and then expand the 118GB partition to use the unallocated space.  Suggest using this tool:  MiniTool Partition Wizard

Also, you can use the information below to free up space on the first drive:

In addition, I have found the utility Cleanmgr+ to have LOTS of options for removing Windows junk, including log files. I use it practically every day. You can get it from here:

Also, there is a freeware app known as Wise Disk Cleaner. I use it every day to get rid of junk files: https://www.wisecleaner.com/wise-disk-cleaner.html
