To mount an ISO on Windows 11, right-click the ISO file in File Explorer and choose Mount. Windows will create a virtual disc drive, assign it a drive letter, and usually open it so you can browse its contents like a real disc. When you have finished, right-click that virtual drive and choose Eject to unmount it. You do not need extra software to mount a standard ISO on Windows 11. If you still need to make an ISO first, get WinBin2Iso from the WinBin2Iso download page.
Mounting is the simplest way to check an ISO you have just made with WinBin2Iso, and it is also the simplest way to use an ISO without burning it to a disc. WinBin2Iso itself does not mount images: it converts BIN and MDF files to ISO. Mounting is a Windows feature that happens after conversion. If you have just converted a file, start from the guides to convert BIN to ISO on Windows 11 and verify an ISO after conversion, then use this guide for the mounting step itself.
Step-by-step: mount an ISO on Windows 11
- Find the ISO file. Open File Explorer and go to the folder that holds the ISO. Make sure file extensions are visible if you are unsure which file is the ISO: in File Explorer, choose View, then Show, then File name extensions.
- Right-click the ISO and choose Mount. Windows will mount the image and assign a drive letter. File Explorer may open the new drive automatically. If it does not, open This PC and look for the new drive there.
- Browse the contents. Open folders, read documents, and open a few files to confirm they are readable. Copy files out if you need them on your PC: see how to extract files from an ISO for the mount-and-copy method.
- Eject when done. Right-click the virtual drive in This PC or in the File Explorer sidebar and choose Eject. The drive letter disappears, and the ISO file itself stays untouched in its folder.
If Mount is missing from the menu
Mount is a Windows feature, so if it is missing, the cause is usually in Windows, not in the ISO file. First, confirm the file really ends in .iso and is not a shortcut or a partially downloaded file. Next, check whether another program has taken over the ISO file type. Some disc tools, archive tools, or virtual-drive programs change the right-click menu for ISO files, and Mount may be hidden under a different entry or replaced by that program’s own mount command. If you recently installed such a program, check its settings or use Open With to open the ISO with Windows Explorer.
Another common cause is that the ISO file is on a drive or in a folder with restricted permissions, or the file is locked by another program. Close programs that might be using the ISO, copy the ISO to a local folder such as Documents, and try mounting from there. If the ISO still will not mount, it may be incomplete or corrupt. Do not delete the original BIN file yet if this ISO came from a conversion: go back to an ISO that will not mount or looks corrupt and work through the checks there, starting with whether the conversion finished without an error.
What mounting does and does not do
Mounting lets Windows read the ISO as if it were a disc in a drive. It does not change the ISO file, burn a disc, or install anything. Files you copy out of the mounted drive are copies: the originals stay inside the ISO. If you edit a file inside the mounted drive, Windows will usually refuse or the change will not be saved back into the ISO, because an ISO is a read-only image format in this use. To change contents, copy files out, edit the copies, and, if you need a new disc image, create a new image from the edited files with a suitable tool.
Mounting also does not make a non-bootable data ISO bootable, and it does not repair a damaged image. If a mounted ISO shows no files, shows garbled names, or fails to open files, the image may be incomplete or may have come from a disc type that does not translate cleanly to ISO. For audio CD images, mounting an ISO made from a multi-track BIN can show only part of the original disc, because a single ISO can lose track structure. For audio discs, keeping the original BIN and CUE pair or mounting that pair is often safer.
FAQ
Do I need WinBin2Iso to mount an ISO? No. Mounting is built into Windows 10 and Windows 11. WinBin2Iso is for converting BIN and MDF files to ISO. Once you have an ISO, Windows handles mounting on its own.
Where does the mounted drive go after I eject it? The virtual drive disappears from This PC. The ISO file remains in its folder, unchanged, and you can mount it again any time by right-clicking it and choosing Mount.
Can I mount an ISO from a USB drive? Yes, as long as Windows can read the USB drive and the ISO file is complete. For the fastest and most reliable check, copying the ISO to a local drive first can help if the USB drive is slow.
Why does my mounted ISO look empty? The ISO may be incomplete, the conversion may have failed part-way, or the original disc type may not translate to a single ISO. Keep the original BIN file, re-check the conversion, and see the corrupt-ISO guide linked above before deleting anything.
