An ISO image is a digital copy of an optical disc: think of it as a CD or DVD packaged into one .iso file. In Windows 10 and Windows 11, you do not need blank media, a disc drive, or third-party mounting software just to inspect it. File Explorer can mount a standard ISO as a temporary virtual DVD drive, letting you browse and copy its contents like files from any other drive.

That is particularly handy when you need one driver, a document, an installer, or a recovery utility from a larger disc image. It is also less dramatic than burning a DVD in 2026, which is surely a sentence our younger selves would have found futuristic.

Windows File Explorer shows a 1,245-item copy to the Desktop at 62% complete. Before you start: know what mounting does​

Mounting does not unpack or permanently extract an ISO. Windows presents the image as a new, read-only virtual drive with its own drive letter, such as D: or E:.

That distinction matters:

  • You can open and copy files from the mounted image.
  • You generally cannot save changes back into the ISO through File Explorer.
  • The original .iso file stays where it is.
  • Ejecting the virtual drive removes the temporary view; it does not delete the ISO.

For ordinary browsing and copying, this is exactly what you want.

Mount an ISO in File Explorer​

  1. Open File Explorer. Press Windows key + E if you want the fast lane.
  2. Browse to the folder containing the ISO file.
  3. Locate the file ending in .iso.
  4. Right-click the ISO file and select Mount.

Windows should create a virtual optical drive automatically. In File Explorer’s left navigation pane, select This PC and look under Devices and drives. The mounted ISO normally appears with a disc-drive icon and a drive letter.

You can then double-click that new drive to view its folders and files.

Another quick method​

On many Windows 10 and Windows 11 systems, double-clicking an ISO also mounts it. If double-clicking opens an archiving program instead, that program has probably taken over the ISO file association. Right-clicking the ISO and choosing Mount is the more reliable File Explorer method when it is available.

Copy the files you need​

Once the ISO is mounted, copy files exactly as you would from a USB drive or a folder on your PC.

  1. Open the virtual drive under This PC.
  2. Browse to the file or folder you need.
  3. Select it, then press Ctrl + C.
  4. Open the destination folder on your PC—for example, Downloads, Documents, or a dedicated working folder.
  5. Press Ctrl + V to copy the item.

Alternatively, right-click the selected file or folder, choose Copy, then right-click in the destination folder and choose Paste.

For large folders, wait for the copy operation to finish before closing File Explorer or ejecting the image. Once copied, open the destination folder and confirm the files are present. This is a small check that can save a large amount of muttering later.

Key point: Run installers or open documents from a copied folder when you want a durable working copy. Files launched directly from a mounted ISO can stop being available as soon as the image is ejected.

Eject the ISO when finished​

When you no longer need the virtual drive:

  1. Open File Explorer and select This PC.
  2. Right-click the mounted virtual DVD drive.
  3. Select Eject.

The drive disappears, while the original ISO file remains untouched in its original location.

Do not confuse this with deleting the ISO. Eject disconnects the temporary virtual drive. Deleting the .iso file removes the disk image itself.

If the ISO will not mount​

Most ISO mounting problems are mundane rather than mysterious. Start with these checks.

Make sure it is actually an ISO file​

File Explorer may hide known filename extensions. A file called Windows11.iso.zip, for example, is a ZIP archive—not an ISO that Windows can mount directly.

To verify, right-click the file and select Properties. Check the file type and name extension.

Copy it to local storage first​

An ISO stored on a network location, removable device, or cloud-synced folder can behave differently from a local file. Copy the ISO to a folder on an internal drive, such as a folder under Downloads or Documents, then try mounting that local copy.

Check whether it is already mounted​

If Windows says the file is in use, it may already be mounted. Look under This PC for an extra DVD drive. If you find it, open it or eject it before trying again.

Restart File Explorer or Windows​

If the virtual drive does not appear after mounting, close File Explorer windows and open it again. A PC restart is also a sensible next step if Windows has become confused about mounted media—a rare occurrence, but Windows occasionally enjoys a brief interpretive dance.

Consider a damaged or incomplete download​

If the ISO mounts but files fail to copy, or if mounting repeatedly fails, download the image again from its original trusted source. For Windows installation media and other security-sensitive images, use the publisher’s official download source and verify any checksum or signature that publisher provides.

Optional: mount and eject with PowerShell​

File Explorer is the right choice for most people, but Windows also includes PowerShell commands for repeatable or scripted work.

To mount an ISO, open PowerShell and run:

Mount-DiskImage -ImagePath "C:\Path\To\YourImage.iso"

To eject it later:

Dismount-DiskImage -ImagePath "C:\Path\To\YourImage.iso"

Microsoft’s PowerShell documentation confirms that Mount-DiskImage mounts ISO files as normal disks, while Dismount-DiskImage removes that disk access. It also notes an important practical limitation: ISO images are mounted read-only. That is why copying files out is the correct workflow, rather than trying to edit files inside the mounted image.

A final security note​

Mounting an ISO is not inherently risky, but an ISO can contain software just as a physical disc can. Treat unfamiliar images with the same caution you would apply to a mystery USB stick found in a conference-room drawer.

Before running anything inside an ISO:

  • Confirm where the ISO came from.
  • Scan it with your security tools if its origin is uncertain.
  • Be especially cautious with unexpected setup programs, scripts, cracks, or “activators.”
  • Keep the original ISO if you may need it again, but store it somewhere you can identify later.

Mount, copy, verify, eject. That is the whole routine—and it is one of those quiet Windows features that saves time precisely because it refuses to make a production out of the job.
