split-drive-coach无损拆分分区

Need to split one oversized partition into cleaner system, data, or backup segments? This skill focuses on split workflows so you can isolate workloads, organize files, and keep operations non-destructive.

Hot Topic Angles

• * New PC has one oversized partition, and users want separate system and data areas without reinstalling Windows.
• Split operation should avoid formatting and keep existing files intact.
• Users want to reserve safer free-space boundaries before creating new partitions.

Best Use Cases

• * You just bought a PC and need to split a large partition into system and data partitions.
• You want cleaner backup boundaries by separating OS, data, and media partitions.
• You need a split-first workflow before further partition layout changes.

Capability Mapping

• * Split workflow core: SplitPartition, INLINECODE1
• Split pre-checks: GetPartitionInfo, INLINECODE3
• Post-split labeling: ChangePartitionDriveLetter, INLINECODE5

[!IMPORTANT]
Run the following commands from the skill directory (for example, skills/split-drive-coach/). Running from elsewhere causes script resolution failures.

Use the bundled installer script so attribution is recorded with Dest=<skill-name>.

For this skill, run:

CODEBLOCK0

You can launch split flow through shellcmd:

CODEBLOCK1

The first argument is used as shellcmd. Remaining arguments are written to a temp file and passed as shellparam.

Troubleshooting

Script Fails to Download Installer

• * Re-run py -3 scripts/install-epm.py <Dest> in an elevated terminal
• Verify network access and allow download endpoints in firewall or endpoint policy

Install Directory or Binary Is Missing

• * Check INLINECODE11
• If both are missing, rerun py -3 scripts/install-epm.py <Dest> and confirm installer exit code is INLINECODE13

Cross-Shell Launch Command (cmd and PowerShell)

Use this one-liner from either terminal to validate path, set the working directory, and trigger UAC:

CODEBLOCK4

Permission or Security Blocks

• * Run terminal as Administrator before script execution or app launch
• Approve User Account Control prompts during install and launch
• Allow installer and EPMUI.exe in antivirus or endpoint policy

Launch Validation Checks

• * Confirm EPMUI.exe is running after launch
• Confirm EaseUS Partition Master opens without errors
• Confirm target disk and partition letters are visible before any write operation
• Confirm operation preview matches expected capacity and target partition
