    How to Change Default Drive


    I recently purchased a new laptop.
    Windows Version: 19042.928
    The computer has 2 drives.
    A C drive: 119GB (44GB used) and a D drive: 931GB. (not used.)
    The C drive contains the recovery partition.
    When files download from One Drive they are going to the C drive, apparently the default drive.
    There is not enough space on the C drive to hold all my files.
    I have already had to erase the computer twice.
    I went into settings and tried to change the Drive from C to D - but it said that I did not have "full control".
    How do I change the default drive to the D drive, so that I have space for all my files, folders, and programs?

    You have to change the Location of Onedrive on your computer.

    Here are Tutorials (by Brink)

    HI,

    BIB, what do you mean by this?

    I am assuming your C drive is a 120gb SSD and your A drive is 1tb HDD?

    I know nothing about "one drive" as I don't use it, it's 50/50 on these forums, love it or hate it.

    What you have found however is the limitations with manufactures hoping consumers will only use the OS drive for that purpose the OS and storing only minimal data/downloads, transferring anything not immediately required to the secondary, larger drive, it just doesn't work that way.

    If you can, clone or mirror image and install a larger SSD, 250gb.

    As AndreTen says, you just have to assign another path for you OneDrive files. Or if you'd like, you can leave them in the cloud, so they wouldn't take space on your hard drive, no mater which one.

    Changing default from C to D may not be the solve-all answer that many believe it is.
    Some software installs insist on C, some don't care. Any major Windows reinstall puts you back to square one. I think any Windows Repair Install will have problems with that split C and D operation.
    I hope you plan on making dual full image backups of both C and D during any single backup session. If a Restore is ever needed, I think you will have to a Restore of C, a Restore of D, one right after the other, before allowing Windows to boot and load. If I'm incorrect, others will enter in and correct me. :)

    Can the C drive and D drive be replaced with one hard drive?

    Sure.......but there's a number of good reasons why you shouldn't. Having 2 separate drives has its advantages.

    You can do it with hardware change, or with software, but like it was stated above, not recommended (dynamic disks).

    Replacing hardware is always a good option. 500 GB M.2 drives are going around $60 atm.

    My advice (with your current setup):
    - keep your system and apps on C: (128 GB) is enough if you don't have a lot of really large applications.
    - move your User data (pictures, documents, downloads, etc) on your D: drive

    It is also easier to backup and image your partitions separately.

    Tutorial: Move Location of Documents Folder in Windows 10

    do teh same for Pictures, and other User folders. Tutorial for moving Onedrive is already above.

    Is it and isn't that the issue the OP is having, constantly having to transfer data/applications to the other larger drive?

    Taking in to account, 120GB SSD isn't and what's left, 60+gb is taken up with the OS, not an awful lot left for data + although such a small OS drive does force you to keep the desktop tidy and in order and possibly boots quicker to.

    Taking in to account, 120GBs isn't and what's left, 60+gb is taken up with the OS, not an awful lot left for data + although such a small OS drive does force you to keep the desktop tidy and in order and possibly boots quicker to.
    Of course that stands if OP moves all of problematic folders to D: (guess this is 1 TB drive). Instructions are provided in links to Tutorials for Onedrive (which could also be set to keep files online only), and other Users folders (Documents, Pictures, Videos, Downloads...)

    Check which folders are problematic with Treesize free or similar
