    DProgrammes x86

    DEF

    I don't know when it started, and deleting files becomes slow.At first I thought the computer was slow after using it for a long time, but later I found that the recycle bin actually reached the D drive; but I did nothing.
    The Programmes x86 folder even appeared on the D drive, which made me look awkward.

    As shown in the figure, there is a lock on D disk, but E disk and F disk do not.

  2. how to merge c drive and d drive

    It depends on a couple things.

    If you have two separate physical C and D drives, you can't merge them.

    If the D drive is a partition (not a drive) and its to the right of C:\ in Disk Management, you can right click C:\ then click Extend.

    Press Windows key + X

    Click Disk Management

    Take a screenshot then post in a reply here.

    If the layout is similar to how I described it, try the following. Make sure important data is backed up if there is any.

    Select the D:\ partition

    Right click the ‘D:\’ in Disk Management, on the contextual menu, click the ‘Delete Volume’ option. Click ‘Yes’ when the warning dialog appears.

    The Volume you deleted will now appear as ‘Free space’, you will also notice that the disk icon no longer appears in the list of volumes.

    Right click the Free space partition, and click Delete, click Yes on the Disk Management warning that appears.

    The volume will now appear as Unallocated. Our next step is to merge back that unallocated free space with the system partition (C:\). Right click the System volume and click the ‘Extend Volume’ option on the contextual menu, click ‘Yes’ when the warning appears.

    A wizard will now begin that will guide through the steps to merge back the unallocated space with your system partition.

    The wizard provides a simple procedure to merge back the unallocated space with the system drive. Once you have selected the space, click Next, at the end of the wizard, you will see the amount allocated.

    Win 10 Parallel Installation - Win 8.1 in C: Drive & Win 10 in D: Drive

    You can do this but it is a little trickier. Here is my advice:

    • If I understand correctly, you have 2 partitions at this moment: a drive C were your current windows resides and a drive D, probably with your files (this is also my setup)
    • The first step will be to create a partition for Windows 10 (cut part of drive D). You can do this in disk manager. If you don't know how, please ask and I will give you the details
    • Create a system image of your current Windows
    • Upgrade your current Windows to Windows 10 (you cannot skip this part if you want the free upgrade)
    • Restore your previous Windows to it's current location (partition)
    • Do a clean install of Windows 10 in the partition you reserved in step 2
    Windows 10 will see that you have another windows installation and add it to the boot manager. At this point you will be able to boot both Windows versions

    No C: but D: drive has all the data

    Hi Austin,

    To help you with your concern regarding the data on the drive C:, you're seeing the drive "C:" as the drive "D:" because you're booting your computer outside Windows. When booting your computer outside Windows, the system is reading the recovery partition
    as drive C: and the data in the drive C: \ are listed on the drive D: \. Try to boot your computer and try to check again the data in the drive C: \ and see if the data are listed.

    Regards.
