Key features

1. Up to four panes in one window

Thumbnails for drawings, a detail list for documents — every pane remembers its own folder and view. Copy or move from one pane to another without juggling windows. Korean initials work in search too — the last pane above shows the result of searching ㅍㅁㄷ (평면도).

2. Fix files on the spot, without opening another app (F4)

Image editor	Excel (.xlsx) editor

Images: crop, rotate, resize, colour, effects and drawing (arrows, text, mosaic). Text: a text editor with Text Cook. Areas hidden with mosaic are really thrown away and cannot be recovered. The original stays untouched until you press save.

3. Sync and backup with a preview (F10)

See what will be copied in a table first, then run it. Pick one-way backup (new and changed files only) or two-way sync.

4. Servers, phones and discs like local folders

SFTP, SMB, FTP, WebDAV and Android phones (MTP) open straight from the sidebar, and an SFTP/SSH folder gets a remote terminal. On Windows you can read Linux EXT4 partitions too.

5. Mistakes can be undone

Ctrl+Z undoes copy, move, delete and rename, 20 steps deep; permanently deleted files (Shift+Del) can be brought back for 3 days. Copying to a USB drive is only reported as finished after it has really been written.

And also

Beyond the five key features above:

• Every folder keeps its own look. Big thumbnails for photos, details for documents — view mode and sort order are remembered per folder and come back next time.
• Search as you type. The search box lives in the title bar. Pause typing and it searches every subfolder, results grouped by folder; filter by text inside files, date or size.
• Burn CDs, DVDs and Blu-rays without another program. Data discs, audio CDs and disc images, checked against the originals after burning.
• The same app on both systems. Same screens and the same shortcuts on Windows and Linux.

Features

Getting around

• Path bar — click a block to go there. Clicking the current folder copies its path; select a file and a file-name block appears at the end that copies the file's full path. Click empty space or press F12 to type a path (~ works)
• Back, forward, up — Alt+←/→, Backspace or Alt+↑, mouse buttons 4 and 5
• Bookmarks — standard folders plus your own. Hold Alt to see their numbers and jump with Alt+1–9
• Recent folders (the last 10, kept across restarts) and recent files — files your browser downloads are added automatically
• Type to jump — type in the list to jump to the first matching name. Korean initials work (ㅌㅇ → 태양, 토양); Space goes to the next match; Shift+Space or the Han/Eng key switches between Korean and English
• Single-click — turn on ① to open folders with one click

Views — remembered per folder

• Details (Ctrl+1) · list (Ctrl+2) · small/medium/large icons (Ctrl+3–5), Ctrl+wheel cycles them
• Sort — name, size, date, extension (Ctrl+6–9, status-bar buttons, column headers); Ctrl+0 fits column widths
• Quick filter — in details view, click an extension or date cell to show only that extension or that day; click again or press Esc to clear
• Thumbnails — images (HEIC included), videos and PDF first pages, visible items first, cached for next time
• Subfolder grid (Ctrl+Tab) — folders as a grid on top, files below; only in folders where you turned it on
• Hidden files (Ctrl+H), font size (Ctrl+↑/↓, Alt+wheel), columns that widen with the font
• Themes — icon theme, folder color, sidebar and list row height, 12 interface languages

Search

• Title-bar search box — always there (Ctrl+F); searches the folder of the pane you used last, including all subfolders
• Results grouped by folder — click a folder row to go there; icon and thumbnail views work on results
• How to search — Korean initials (ㄷㅁ), several words (plan+.pdf), patterns (*plan*.pdf, ? = one character)
• Search options — inside text files (up to 5 MB), date (today, this week/month/year), size, files or folders only
• Work right in the results — open, copy, move, delete, preview, drag into other apps, compress, extract. Results stay after opening a file; Back closes the search
• Select by pattern (Ctrl+Shift+S) — e.g. every *.jpg in the current folder

Working with files

• Copy (F7) · Move (F6) — a folder chooser with bookmarks and devices; the progress window shows remaining size and speed, and queued items can be removed. On USB and other removable media the copy finishes only once the data is really written
• Clipboard — Ctrl+C · Ctrl+X · Ctrl+V, also with other file managers
• Rename (F2) — starts with the name selected, extension excluded
• Batch rename (F8) — prefix, suffix, find and replace, numbering, new name, with a preview
• New folder (Ctrl+N), new folder with selection, new file from template, F4 with nothing selected for a new text file
• Delete — Del moves to the trash, Shift+Del deletes permanently, yet the last 50 are kept for 3 days so Ctrl+Z can restore them; review or empty them in Settings → Deleted Files
• Trash (Ctrl+Shift+T) — select and press R to restore
• Undo (Ctrl+Z) — create, delete, copy, move and batch rename, 20 steps
• Stars and tags — starred files gather in the sidebar; tags are written into the file itself (Linux extended attributes / Windows NTFS streams) and follow it when moved
• Open with — remembers the last app chosen for each file type
• Properties — size, path, dates, folder file count and size, permissions, image/music/video details, combined size of several items, and the prompt, model and settings of AI-generated images
• More on right-click — open in new window, open file location, open or run as administrator, install a .deb package (with a [Run] button afterwards), Nautilus scripts (Linux)

Drag and drop

• Dropping files opens a menu: copy, move or shortcut — no guessing what happened
• Hold Shift while dropping for a copy with a new name, no menu
• Swipe across files to select them, like on Android — nothing moves by accident
• Path-bar blocks, the sidebar, other panes and other apps (browsers) accept drops too

Basket and archives

• Basket (Alt+B) — collect files from many folders, then compress, copy, move or delete them at once from 🧺 in the status bar
• Compress — zip · tar.gz · tar.bz2 · tar.xz · 7z
• One archive from several folders — keep the Compress window open, select files in another folder or pane and press "Add Selection" or drag them in; search results work too
• Extract — double-click an archive to extract it into a folder of the same name, or right-click → Extract Here

Split panes (2, 3, 4)

• F1 or ◫ in the status bar for two panes; the right pane's ◫ adds a third, the third pane's ◫ a fourth
• Each layout remembers its pane ratio and every pane's folder
• Yellow ★ — while split it saves the pair of folders; in single mode (or from the yellow ★ in the sidebar) it restores them
• In 3–4 pane mode, enlarge the active pane and dim inactive panes (color selectable)
• Three window sizes (Ctrl+S); size and position are remembered

Sync + Backup (F10)

• With two panes open, left is the source and right the target
• One-way backup (new and changed files only) or two-way sync (newer files both ways). Files on only one side can be copied over or deleted
• Match by name regardless of folders; treat files of the same size as identical
• Text and source files only (decided by content, not extension), plus extensions to always include or exclude
• Preview every change in a table, then run

Viewing

• Viewer (F3) — images, PDF, text, music and Excel (.xlsx) in one window
  • ←/→ previous/next file of the same kind, Home/End first/last
  • Images: slideshow (Space pauses), full screen (F), rotate (R/Shift+R), "Apply to all photos" keeps the angle for the next ones
  • PDF: pages (PgUp/PgDn), zoom (+/-) · text: find (Ctrl+F) · print (Ctrl+P)
• Quick preview (F11) — images, text, music and video beside the list as you select. Music turns the folder into a playlist and skips unchecked songs. With "keep playing after closing", music continues after F11 closes and a small player bar remains. Choose the audio output device
• Compare (Ctrl+D) — two files side by side, differences marked
• Terminal (F9) — in the current folder

Editing (F4)

• Text editor — save (Ctrl+S), find (Ctrl+F), line numbers, font, print (Ctrl+P)
• Text Cook (Ctrl+Shift+K) — cleans up pasted, OCR and subtitle text in one go: tidy OCR text, one sentence per line, join lines within paragraphs, all on one line, tidy spaces, single or no blank lines, subtitle (SRT) dialogue only
• Image editor (F4 on an image)
  • Crop (fixed ratios 1:1, 4:3, 3:2, 16:9 and more), rotate, flip, straighten, resize (25/50/75%, long edge 800–3840 px)
  • Color (brightness, contrast, saturation, hue, gamma, auto), effects (grayscale, sepia, invert, sharpen, blur, border)
  • Drawing — pen, marker, line, arrow, rectangle, ellipse, text and watermark, plus obscure: a mosaic over faces or account numbers that really discards the pixels
  • Fit to a file size — type "250 KB" and it adjusts quality (color levels for PNG) while keeping the resolution; shrinking the image happens only if you allow it
  • Undo (Ctrl+Z), save (Ctrl+S) and Save As — the original changes only when you save
• Excel — open, edit and save .xlsx without Excel

Disc burning — CD, DVD, Blu-ray (Ctrl+B)

• Select files and press Ctrl+B or right-click → Burn to Disc. The burning engine is built in
• Data disc — leave it open to add more later, or close it. The burned files are checked against the originals
• Audio CD — MP3, FLAC, OGG, M4A, WAV and more converted to CD quality; reorder the tracks
• Disc image — burn an ISO, or save a disc as an ISO (all sessions of a multi-session disc)
• Erase — CD-RW, DVD±RW, DVD-RAM, BD-RE
• Burn speed — choose from the speeds the drive reports for that disc, or let the drive decide
• Videos that play straight from the disc — phone videos (MP4, MOV) get their index moved to the front in the burned copy only; the originals stay untouched
• Long names stay readable on Windows (up to 103 characters)
• Drives stay in the sidebar even when empty and follow disc changes at once. Disc thumbnails can stay in memory or be saved per disc

Servers, devices and network

• Connect to a server — SFTP · SMB · FTP · WebDAV, like a local disk
• Remote terminal (Ctrl+Shift+C) — in an SFTP/SSH folder, a terminal for that server docks under the file list; run selected files from the right-click menu
• Android (MTP), cameras and network drives appear automatically. "My Devices" lists unmounted disks too; click to mount
• Send and receive files over the network between PCs on the same network
• Windows: read Linux EXT4 partitions — with views, sorting, copying and drag and drop
• Windows: recover permanently deleted files

System integration

• Default file manager — one button from the title-bar icon
• Replaces other apps' open and save dialogs — FileIyagi appears when a browser attaches or saves a file. Gather files from several folders to attach at once, paste a clipboard image directly, and get the next numbered name when saving
• Windows: Win+E opens FileIyagi instead of Explorer
• Three custom buttons — any app or command, with %f for the selected file
• Uses the input method you chose (Korean included)

Linux convenience tools (Settings → Convenience)

• Hibernate and screen lock — find out why suspend, hibernate or locking fails and fix it in one step, including programs that block sleep
• Log analysis — why the PC went down and why apps crashed, as causes and fixes instead of raw logs
• Journal flood guard — stops one program from filling the disk with logs
• Extract audio from video — without re-encoding, and merge it back; reads damaged AVI files
• System information — hardware specs, driver and PCI ID per device, firmware errors, USB, temperatures; everything can be copied
