Usage Guide

LRGEX Compress is designed to be used entirely from the Windows right-click (context) menu. You never need to open an app.

Compress

  1. Right-click any file or folder in Windows Explorer.
  2. Click LRGEX → Compress.
  3. A progress window appears showing live speed and ETA:
    • Percentage complete
    • MB/s (megabytes per second)
    • ETA (time remaining)
  4. When it finishes, a .zgx archive appears next to your original file/folder.

The archive is named after the folder. For example, compressing MyGameSaves creates MyGameSaves.zgx in the same directory.

Compressing multiple files at once: Select multiple files or folders in Explorer, right-click one of them → LRGEX → Compress. LRGEX creates a single .zgx archive containing all of them.

Extract

Right-click any supported archive → LRGEX → Extract or LRGEX → Extract Here.

Extract (to a subfolder)

Creates a new folder named after the archive and extracts everything into it.

  • Right-click MyBackup.zgx → LRGEX → Extract
  • Result: a new folder MyBackup\ containing all the files

Extract Here

Dumps the archive's contents directly into the current folder — no subfolder.

  • Right-click MyBackup.zgx → LRGEX → Extract Here
  • Result: the files appear right next to the .zgx

Supported formats

Format Can compress? Can extract?
.zgx (LRGEX native — tar.zst) ✅ ✅
.zip ❌ ✅
.rar ❌ ✅

You do not need WinRAR or 7-Zip installed for LRGEX to extract .zip or .rar files.

The progress window

The progress window shows:

  • A progress bar with percentage
  • MB/s (current speed)
  • ETA (estimated time remaining)
  • A spinner that animates even when the percentage isn't moving (e.g., waiting on a large file) — so the window never looks frozen

Cancel is always available during compression. When you cancel:

  • The partial archive (.part temp file) is deleted — the final .zgx only appears when compression is 100% complete
  • No broken files are left behind

The window closes automatically 2 seconds after the operation finishes successfully.

Where do archives go?

Archives are always created next to the source — in the same folder as the file/folder you compressed. LRGEX never puts files anywhere else without asking.

What settings can I change?

None. That's the point. LRGEX always uses optimized defaults (zstd level 1, all CPU cores, atomic writes). There are no compression levels, no dictionary sizes, no solid-archive options. It just works.
