How to work with disk image files


PeaZip offers full read / write support for Microsoft WIM archives.
The software also provide read only support (view, browse content, extract from) for many disk image standards, like ISO, UDF, MDF, Apple DMG packages, IMA/IMG/IMZ images, Microsoft VHD for Virtual PC, QCOW2 (QUEMU virtual disk), VMDK VMWare Virtual Machine Disk, VDI Oracle VirtualBox Virtual Drive Image.
Please note editing and burning to physical disk such image files formats is out of the scope of PeaZip, you will need an appropriate software (i.e. an ISO disk image authoring) tool to create or update read-supported image formats.

As alternative, 7-Zip (on MS Windows systems) and p7zip (on Linux/BSD), both free and Open Source tools, are recommended for working with those disk image file formats.

Create WIM image file

Use one of the following procedures to add files / folders to a new or into an existing image file (select WIM from archive format picker in output options are)

  • From the system's file explorer

    • Select files and folders and use context menu entry PeaZip, Add to archive: you will be prompted to archive creation screen, allowing to set output destination, and other options.

  • From PeaZip (faster)

    • Select files and folders, and use Add button (or application's context menu entry of same name) to be prompted archive creation screen

    • Drag and drop files / folders from the system to a PeaZip instance; if you are browsing an existing archive you will be asked if you want to add files to the archive or create a new one


Update existing WIM archive


To update existing archive, adding files and folders, proceed as shown above for archive creation, but select an existing archive as output and chose add (always replace files in archive) or update (overwrite only older files in archive) "archive function" in advanced tab.
Easiest way to edit an existing archive is opening it in PeaZip and dragging files/folders to it, which will automatically activate update mode - can be changed into add mode in advanced tab.

To remove (delete) data from the archive, select items and press cancel or "Delete from archive" button. Deleted items will not be recoverable from recycle bin.
Entries in the context menu on the right of delete button allows to delete the entire archive in different supported ways (recycle, quick delete, overwrite with zeroes, secure delete shredding data to make the archive not recoverable)

Convert image files


File converter procedure using Convert button extracts any read supported format (including iso, udf, dmg, vmdk, vdi, wim...) and then re-pack it into any write-supported format (7z, arc, pea, tar, wim, zip...), optionally keeping or discarding original archives.

This makes possible to convert each individual input archives in the new format, or consolidating all input items into a single output archive of the selected new format.

Open and extract image file (ISO, DMG, UDF, VMDK, WMI...)


Use one of the procedures described below to open (browse and search inside the archive) and/or extract content from a disk image / virtual machine disk file
  • From the system

    • To view disk image's content, open it in PeaZip with double click (if file extension is associated with the application), or using system context menu "Open as archive" entry, that will attempt to read any user provided file type regardless file type associations - this option is also available in PeaZip's context menu

    • Use context menu entry "Extract..." for full extraction screen GUI where to set output path and other options

    • Select one or more archives and use context menu entry Extract here or Extract here (to new folder) for quick extraction with no further confirmation

  • Within PeaZip

    • Extract button shows full featured archive extraction screen providing access to all options (password, set output path, open output path after extraction, keep or delete original archives, etc) and can send to extraction selected items only

    • Extract all to... button activate a simplified dialog only asking for output path

    • Simply drag & drop desired objects from the application to the system (easiest way)

    • Doubleclick on a file inside the disk image to open it in preview mode, i.e. to inspect its content before considering the need for real extraction


Manage encrypted image files


In case the image file is password protected, you can add a password clicking on locker icon when viewing the archive, or in extraction screen.
