【2026 File Management】한글 (HWP) file recovery: 3 mechanisms + Keeply timeline layer

Hancom Hangul has 3 recovery mechanisms built in. Readers confuse all three as “version history” — each only solves one problem.

“The night before a paper deadline, 한글 crashes without saving — you open 한글, see an ‘auto-recovery’ popup, and 80% of your 3 hours of work comes back. But the version from 3 weeks ago for that proposal? You dig through ~AutoSave/ — gone.”

This is the real limit of 한글’s 3 built-in recovery mechanisms (Autosave / Temp save / Backup file): they solve crashes + last-version rollback, not time-based history. This article unpacks the differences between the three + how Keeply fills the timeline gap as a cross-tool layer.

How Keeply makes HWP files “the version from 3 weeks ago is still there”

Here’s what happens. Jiyeong is a civil servant. She writes her monthly report report.hwp in 한글 — 100+ saves accumulated over 6 months. Today her supervisor suddenly asks: “Can you show me that section from the version you sent 3 weeks ago?” She opens 한글’s “Recent files” — only goes back to last week. Opens ~AutoSave/ — only crash-recovery temp files. Opens report.hwp.bak — only the most recent 1 version. All 3 recovery mechanisms fail to retrieve the 3-week-old version.

In Keeply, it’s different. Same report.hwp looks like this in the Keeply timeline:

“Submitted to supervisor v2 — monthly report” gets its own row with a Release tag — that’s Jiyeong three weeks ago, after submitting to her supervisor, hitting “Save version” in Keeply’s main window and writing a note:

Write “Submitted to supervisor v2 — monthly report”, save the version. Three weeks later, scrolling Keeply’s timeline, the tag is right there — not bound by 한글’s limited temp folder.

Two actions, total:

1. Save — Ctrl+S in 한글 as usual. 한글 writes .hwp to the folder. Keeply polls in background within 30 min, sees the change, auto-saves a version to its own timeline.
2. Mark milestone — at significant moments (supervisor signoff / client approval / month-end seal), hit “Save version” in Keeply’s main window and write a note.

Below: unpack 한글’s three mechanisms — why all three fall short.

HWP 3 recovery mechanisms

When 한글 says “file recovery,” it’s actually three different things blended:

Three different things — confused as one, you’ll look in the wrong layer. “Can’t find the version from 3 weeks ago” might be autosave temp already deleted, .bak already overwritten by a new save, or backup file not enabled. Each mechanism only solves one scenario.

Autosave: crash recovery, not version history

한글 Preferences → Autosave saves a copy every 10 min by default to ~AutoSave/ (path configurable).

Only useful in:

• 한글 crash (application error)
• Force-quit (terminate from Task Manager)
• System power-off / forced restart
• Closing without saving — “Recover?” prompt on next open

Completely separate from version history: autosave doesn’t keep multiple versions (just the most recent 1 temp), can’t find “the version from 3 weeks ago.”

See Photoshop autosave isn’t version history — Adobe has the same autosave-confusion pattern.

Temp save .bak: 1-version backup

Every time you save an HWP file, a <filename>.bak copy is auto-generated in the same folder — the version just before the last save.

Key limits:

• Only 1 version: each save overwrites the old .bak, no version stacking
• Solves “saved this one wrong” scenario: can’t go back further
• Optional in settings: can be disabled in Preferences (default on)

Reader misconception: “.bak is version history” ❌. Actually just “most recent 1 version” record.

Backup file: configurable in Preferences

한글 Preferences → Backup file / Temp save can enable automatic .bak generation. For users who have it enabled, same mechanism as the previous .bak section (just different setting location).

Still 1-2 version limit, not true version history. Doesn’t help with “the version from 3 weeks ago” need.

The real scenario where all 3 fail

Jiyeong’s scenario analysis:

The bottom 3 ❌s are “time-dimension” needs — none of the 3 HWP built-in mechanisms cover this layer.

Keeply fills the gap: cross-tool timeline + Release freeze

How does Jiyeong solve “find the version from 3 weeks ago”? Switch to Keeply. Three things in one tool:

• Cross-tool timeline: Keeply watches the folder, after each Ctrl+S saves 1 version to its own timeline — not dependent on 한글’s limited ~AutoSave/. Six months of saves = six months of version history (not 1-2 versions)
• Release freeze: 3 weeks ago when submitting to supervisor, Jiyeong hit Keeply “Save version” with tag “Submitted to supervisor v2” — this version is frozen as a separate snapshot, not overwritten by subsequent saves, preserved permanently
• Per-file note: each version carries 1-2 lines of notes (“Supervisor submit v2”, “Client requested ch.3 revision”), three weeks later just scroll the timeline and find the tag instantly

Runs alongside HWP’s own autosave / .bak — no conflict. 한글 handles crashes + last-version rollback, Keeply handles time history + important-version freeze.

3 HWP scenarios where you don’t need Keeply

Honest list:

Locked-down environment / government / education. If you’re a civil servant or teacher using an IT-issued locked-down PC (no external software allowed) — don’t force this. Follow your IT department’s centralized backup policy (Veeam / Acronis). Keeply is for personal PCs / SMB / SOHO, not compliance archive.

Only using 한글 viewer to read others’ files. If you don’t actively edit and only open 한글 viewer for received .hwp files — no version management need, skip Keeply.

Single file, 1-2 saves then submit. One-off short documents (official letter reply / 1-page notice) saved 1-2 times — no timeline need, HWP built-in .bak is enough.

FAQ

Q1: Where does HWP autosave save?

Default ~AutoSave/ (path changeable in 한글 Preferences → Autosave). Default every 10 min, only useful on crash / force-quit, prompt on next open. Not version history, can’t find 3-week-old version.

Q2: HWP .bak vs autosave?

.bak is last-version backup (auto-overwritten every save), keeps 1 version. Autosave is crash temp file, completely different layer from version history.

Q3: Is HWP backup file reliable?

Still 1-2 version limit, not true version history. Insufficient for “3-week-old version” need.

Q4: All 3 fail, how to find 3-week-old version?

HWP built-in can’t recover. Need external tooling for continuous version backup — e.g. Keeply cross-tool timeline.

Q5: Keeply vs Hancom Office?

No conflict, runs alongside. 한글 handles crash / last-version, Keeply adds unlimited timeline.

Q6: Civil servant / teacher, can’t install external software?

Locked-down environment follows IT centralized backup policy (Veeam / Acronis), Keeply personal tool not suitable.

Side-by-side:

• Photoshop autosave isn’t version history — Adobe’s same autosave ≠ version history confusion
• Excel version history limits — Office’s parallel mechanism gap pattern
• What Keeply saves vs backup and cloud tools

Jiyeong submits her monthly report at month-end. 한글 crashes 3 times, autosave rescues each time’s work.

But the supervisor suddenly asks for “the version from 3 weeks ago” — autosave / .bak / backup file all fail to recover.

Hancom has the 3 mechanisms in its docs. You don’t need 한글 to be different — you need a tool that catches the time history when 한글’s mechanisms run out.
