If you don't need them, you can delete installer files. If you plan on reinstalling OS X from scratch (or should you need to uninstall and reinstall a specific application), having installers in a folder on an external hard drive can come in handy and save you time, as you don't have to download them again. A file with the DMG file extension is an Apple Disk Image file, or sometimes called a Mac OS X Disk Image file, which is basically a digital reconstruction of a physical disc. For this reason, a DMG is often the file format used to store compressed software installers instead of having to use a physical disc. While your DMG is mounted, your data has vulnerability level X. This X is the same if you write files in DMG and re-encrypt it and if you only read files by decrypting using the same key that you enter once in both cases. Keep in mind that while disk is mounted, readonly or not, it can be accessed by any software like normal folder.

The point of this article is to help you deal with “Access Denied. You need administrator permission to delete this file” and similar errors. This guide includes steps to take ownership and permission of the file or folder so that you can change settings, copy or delete files without problem.
“Folder Access Denied. You’ll need to provide administrator permission to delete this file/folder.” error is very common in Windows computer. When you access files, you may also encounter other similar errors such as:
- File (Folder) Access Denied. You need permission to perform this action. You require permission from to make changes to this file.
- Access Denied. You will need to provide administrator permission to change these settings. Click Continue to complete this operation.
- Destination Folder Access Denied. You’ll need to provide administrator permission to copy to this folder.
It seems that this is simply a permission issue, but some users do log in as Administrator and still can’t delete files or change settings. Thus error is kind of annoying and looks like a system.
This permission error appears due to the increased security and privacy features of Windows operating system. Some actions require users provide administrator permission to copy / delete /rename files or change settings. Such permission prevents unauthorized users such as guest users, and external sources like scripts from accessing system data. When virus attacks computer, it attempts to again administrator access to operating system so that it takes advantage of system vulnerabilities.
File permission is set to restrict unauthenticated objects from taking full control of files, helping Windows detect whether the user or object can gain special file access and write permission. File access permission can be changed by administrators.
Without proper permission, users can’t perform certain operations and gets error messages mentions above. Therefore we can change access permission and take ownership of system files to get rid of this problem.
- Find the file or folder you want to delete or access from Windows Explorer. Right click it and choose Properties from menu.
- Select Security tab from the Properties window and click Advanced button.
- Continue click Owner tab from the Advanced Security Settings and you can see the current owner is TrustedInstaller.
- Click Edit button and choose user who you want to change owner. If your account is Administrator account, then choose it. Click OK and the current owner becomes the one you just selected. If you want to delete multiple files in a folder, then check off “Replace owner on subcontainers and objects”
- Click OK button on all Properties windows and then close it. Again right click the file or folder that you cannot delete and choose Properties again.
- Click Security tab again and hit Edit button this time.
- Click user name from the list and user name should be the same as the one who you changed the current owner. If it is not is the list, then click Add button to add it to the list.
- Select all boxes under Allow in the Permission for Administrator section. Click Apply and then OK button. Then you can delete file or perform actions without getting error message.

Home > Resources > Make Bootable USB Installer from DMG
(0 comments)
DMG file is a compressed file format being used widely on Mac computer. Windows OS doesn't natively support DMG disk image files, so if you need to create a bootable USB drive from a DMG file, mostly for bootable Mac OS X or macOS installation USB, you need a special utility to help you complete the task.
There is also the possibility of converting the file into a format more suitable for Windows, which is the ISO file format for disk images. Considering the above, let's look at different ways to create a bootable drive from a DMG file on a Windows computer.
Part 1: Convert DMG to ISO and Make Bootable USB from ISO
Since Windows doesn't offer native support for DMG files, you can first convert the file to ISO. Why? A lot of easier to find an app for making a bootable USB from ISO file. The easy way to do this is to use Command Prompt. Don't be intimidated by the non-GUI environment even if you don't have any experience. If you follow the steps below, you can convert any DMG file to ISO and then create a bootable USB using the converted file.
Step 1: Open Command Prompt by typing cmd in the Run windows and hitting Enter.
Step 2: In the command interface, go to the directory in which the DMG file is saved. You can do this by using the 'cd' command followed by the file path, then pressing Enter. For example, if your disk image is in D: and Command Prompt is currently in 'C:', then type 'd:' (no quotes) and press Enter. If it is in a subfolder, type 'cd subfolder', and so on.
Step 3: Use the following command to convert the DMG file to ISO:
hdiutil convert /path/sourceimagefile.dmg -format UDTO -o /path/targetmage.iso
Step 4: Once the ISO file has been created, you can use a burning tool to create the bootable USB drive. To do that, continue with this guide.
Cons:
- File damged or broken after conversion.
- Failed booting from burned USB disk.
- May not work with the latest DMG file.
- Complex and take more time.
Part 2: Create Mac OS X Bootable USB Installer from DMG
Androidphonesoft DMG Editor is a powerful software application for Windows that will allow you to manage the non-native DMG format even if you have no experience. The interface is uncluttered, and you can even use the tool to view files, extract them, edit the DMG and even copy it to a disk. The burn function has one of the highest success rates in the industry, which makes this an ideal utility for our purpose.
Created by the talented team of developers at Androidphonesoft, DMG Editor is currently the most intuitive Windows app for handling Apple's disk image format. Each of its functions have been tested on various Windows versions, with different types of DMG files and on different PC brands. This thorough testing means no wasted DVDs or corrupted files. As long as your DMG file is in good shape, you can directly create a bootable disk.
Step 1 Install DMG Editor
Download and install DMG Editor on your Windows PC.
Step 2 Plug in USB Drive
Launch the application and click on the 'Burn' section. You will also see other modules such as Edit, Extract and Copy.
Step 3 Start Burning ISO File to USB
Now import the DMG file by clicking the 'Load DMG' button, and click on 'Burn'.
In a few moments, your bootable USB flash drive will be ready for use. Since you haven't done any conversion, you can use this directly on a Mac for program installation, which you cannot do with the first method.
Part 3: Create Bootable USB from DMG in Windows Via PowerISO
Another well-known disk image utility is PowerISO. Apart from being ideal for burning ISO files, it can also burn a DMG file to USB to create a bootable drive. There are some settings that you have to keep in mind when burning with this software, but it's easy to get the hang of it once you do it a couple of times.
Step 1: Download PowerISO and install it in your Windows PC. Launch the app and insert a USB drive into a free USB slot in your computer.
Step 2: You can import the DMG file directly by clicking on ‘Burn' in the toolbar or going to Tools >Burn. In the Burn window, select the DMG file from the Source File section.
Step 3:Now review the settings to select the burn speed. The default will be the maximum your hardware can handle, so you can reduce that. You can also choose to finalize the disk and verify it. Finalizing means you can't save any more files on the drive, but it primarily applies to DVDs and CDs. Choosing ‘Verify' will prompt the software to execute an additional process after the burning is done. Any errors in the bootable USB will show up at that point.
Step 4: Now click on 'Burn' and wait for the progress bar to reach 100%. Your bootable USB is now ready.

- Expensive for a single license.
- Higher failure rate for bootable device.
- Ugly user interface.
The Bottom Line:
The second two methods are recommended if you don't have much experience working with DMG files, but DMG Editor will appeal to novices and experts alike. The clean interface and minimal user input means a lower chance of errors while creating the bootable media.
