Split WinISO (by Chandra)

Split_WinISO.exe is now in the MPI ToolKit. You must run it from the MPI folder because it will use MPI to make a .imgPTN file. 

Split_WinISO.exe can also re-make a new .ISO file and convert the large >4GB Install.wim or Install.ESD file(s) into smaller files for you.

It has been written to interface with the Easy2Boot MPI Tool Kit (if it is placed in the MPI folder).

In addition to splitting large .wim/.esd files, it can also add the missing Windows 7 EFI boot file and modify the boot.wim file for automating Windows Setup using XML files (see here for more details).

Load the ISO file and click on CONVERT if the install file is larger than 4GB.

Use the MPI button if you do not want to split the install.wim file.

Troubleshooting

Errror 3 – check the path and filename does not contain any weird characters (like ( or & or =, etc.) – try renaming it. Use 7Zip to open the ISO file and then double-click on the install.esd or install.wim file inside the ISO – 7Zip should list the files inside the .wim\.esd file – if you get an error then suspect that the ISO is corrupt. Check the MD5\CRC32 hash of the ISO – try a different ISO.

Make sure your C: drive (or whatever drive Windows uses for temporary storage) and the drive where the ISO is stored has plenty of free space (at least twice the size of the ISO as free space).

Description :
 
This Windows tool will convert Windows Install ISO files containing large (>4GB) .ESD or .WIM files into a .ISO
file containing smaller split-wim (.SWM) files suitable for use on FAT32 filesystems.
 
Specification :
- Windows utility which can take a Windows Install ISO (or extracted folder) and convert it into another ISO 
  (or to an E2B FAT32 .imgPTN file if you have the Easy2Boot MPI Tool Kit installed). 
- The useful thing about this app is that it will split a large Install.WIM, Install.SWM or install.ESD file into 
  split SWM files automatically. THIS MEANS THAT THE RESULTING FILES CAN BE USED ON A FAT32 FILESYSTEM 
  (e.g. for UEFI-booting).
- Works on the Microsoft ISOs that contain both \x86 and \x64 folders (with two Install.ESD\WIM files)
- Converts SWM\ESD\WIM to .SWM automatically.
- Easy2Boot compatible - just copy the .exe file into the MPI ToolKit folder and run it from there
- Do not run two or more instances simultaneously as it will make the system crash and the engine load is very
  high resource.
- Compressor to Convert ESD, split WIM and merge SWM file. LZD and LZMS compression gives best performance
- Supports converting mixed Install.ESD and Install.WIM files when found in same ISO.
- Portable application (no installation required)
 
Supports official MS ISOs 
1. x86\sources\install.esd + x64\sources\install.esd
2. x86\sources\install.wim + x64\sources\install.wim
3. x86\sources\install.swm + x64\sources\install.swm

NORMAL USE
==========
 
CONVERT Button Function: (ISO or the extracted folder)
1. ESD files -> converted into a large WIM files -> split into small SWM files -> create New ISO or imgPTN (FAT32)
2. ESD files -> converted into a WIM files -> create New ISO or imgPTN (FAT32)
3. Large Wim files -> split into small SWM files -> create a new ISO or imgPTN (FAT32)
4. Large SWM files -> merge into large WIM files -> re-split into smaller SWM files -> create New ISO or imgPTN
   (FAT32)
5. Small SWM files -> merge into small WIM files -> create New ISO or imgPTN (FAT32)
 
Program action:
1. Extract files from ISO or DVD/CD/Folder
2. Convert ESD files (if present) into WIM files and then split into smaller SWM files.
3. Merge large SWM files (if present) into WIM files and then re-split into smaller SWM files.
4. Split any large WIM files into smaller SWM files.
5. Save as ISO file (or .imgPTN file for use with Easy2Boot)
6. (optional for Easy2Boot) Inject winpeshl.ini and Mysetup.cmd into boot.wim
 
Because all files will be less than 4GB, they can now be UEFI-booted from a FAT32 drive volume.
 
REQUIREMENTS:
=============
1. A Win 7/8/10 system is required.
2. ImDisk - download and install imdisk. https://www.ltr-data.se/opencode.html/#ImDisk
3. Administrator access rights required.
4. Use official Microsoft Windows 7/8/8.1/10 Install ISOs.
5. 32-bit + 64-bit combined ISOs are supported.
6. Multiple-image ESD\WIM files are supported.
7. Requires drive U: to be a free drive letter
 
Convert to ISO:
==============
1. Select source - use the ISO button or the PATH button to select a DVD/Folder containing Windows Installer files.
2. The size and type of ESD\WIM files should now be displayed:
   x86  = \x86\Sources\Install.* size+type (ESD\WIM)
   x64  = \x64\Sources\Install.* size+type (ESD\WIM)
   BOTH = \Sources\Install.*     size+type (ESD\WIM)
3. Set the Split Size in MB, between 3-5 digit (e.g. 4000). For FAT32, do not exceed 4000.
4. Press the 'CONVERT' Button.
 
 
USE WITH EASY2BOOT (www.easy2boot.com)
======================================
1. The Easy2Boot MPI Tool Pack is required
2. Copy this application .exe file into the MPI Tool Pack folder and run it.
   You should now see a new MPI button as well as the CONVERT button.
 
CONVERT - converts large ESD\WIM files, you can save it as a FAT32 .imgPTN for Easy2Boot or as an .ISO file.
MPI     - save as FAT32 or NTFS .imgPTN file but DOES NOT SPLIT LARGE FILES
 
Modification of boot.wim (optional):
======================================
1. Both the CONVERT and MPI buttons will also offer you the option to add the files MySetup.cmd and Winpeshl.ini
   into the boot.wim image #2 (Setup) file.
2. Some sample .XML files and the \Auto.cmd will also be copied to the root of the USB drive. These will require 
   changing by the user before use.
3. This allows the user to choose from a selection of XML files (e.g. to install Home or Pro, etc.).
   For more details, see https://www.easy2boot.com/add-payload-files/automating-windows-install-from-imgptn-files
 
NOTES
=====
1. Some antivirus and firewalls may block this tool. Please disable or whitelist as required.
 
2. Some Microsoft ISOs may not support split WIM files. See: https://msdn.microsoft.com/en-us/windows/hardware/
   commercialize/manufacture/desktop/split-a-windows-image--wim--file-to-span-across-multiple-dvds
   If you find such an ISO, please use WinNTSetup instead.
 
3. When converting a .ESD to .WIM, the process will consume very high amounts of CPU and RAM resources which may 
   drastically slow down your system.
 
4. '[WARNING] Failed to enable short name support’ - this warning is normal and can be ignored.

==============
1. Select source - use the ISO button or the PATH button to select a DVD/Folder containing Windows Installer files.
2. The size and type of ESD\WIM files should now be displayed:
   x86  = \x86\Sources\Install.* size+type (ESD\WIM)
   x64  = \x64\Sources\Install.* size+type (ESD\WIM)
   BOTH = \Sources\Install.*     size+type (ESD\WIM)
3. Set the Split Size in MB, between 3-5 digit (e.g. 4000). For FAT32, do not exceed 4000.
4. Press the 'CONVERT' Button.
 
 
USE WITH EASY2BOOT (www.easy2boot.com)
======================================
1. The Easy2Boot MPI Tool Pack is required
2. Copy this application .exe file into the MPI Tool Pack folder and run it.
   You should now see a new MPI button as well as the CONVERT button.
 
CONVERT - converts large ESD\WIM files, you can save it as a FAT32 .imgPTN for Easy2Boot or as an .ISO file.
MPI     - save as FAT32 or NTFS .imgPTN file but DOES NOT SPLIT LARGE FILES
 
Modification of boot.wim (optional):
======================================
1. Both the CONVERT and MPI buttons will also offer you the option to add the files MySetup.cmd and Winpeshl.ini
   into the boot.wim image #2 (Setup) file.
2. Some sample .XML files and the \Auto.cmd will also be copied to the root of the USB drive. These will require 
   changing by the user before use.
3. This allows the user to choose from a selection of XML files (e.g. to install Home or Pro, etc.).

NOTES
=====
1. Some antivirus and firewalls may block this tool. Please disable or whitelist as required.
 
2. Some Microsoft ISOs may not support split WIM files. See: https://msdn.microsoft.com/en-us/windows/hardware/
   commercialize/manufacture/desktop/split-a-windows-image--wim--file-to-span-across-multiple-dvds
   If you find such an ISO, please use WinNTSetup instead.
 
3. When converting a .ESD to .WIM, the process will consume very high amounts of CPU and RAM resources which may 
   drastically slow down your system.
 
4. '[WARNING] Failed to enable short name support’ - this warning is normal and can be ignored.
