CHD Manager 1.4.0

You choose what happens to CHD files, and extraction now sorts out multi-file discs for you

• CHD files choice. When a CHD is in the list, a CHD files choice appears at the top: Extract it, Verify it, or Recompress it with different compression (your original is kept). Right-click a file to give just that one a different action. The Action column always says what will happen.
• Automatic one-BIN-per-track. When extracting a CD, the app reads its track count first. A disc with several tracks (audio plus data) gets one BIN per track; a one-track disc gets a single BIN. No setting to remember. You can still force "one BIN per track" or "one single BIN".
• Tidy batches. Anything that comes out as several files (split CDs, Dreamcast GDI) is put in its own folder named after the disc, so a big batch doesn't turn into a pile of mixed-up files.
• ISO output for data CDs, offered only when nothing would be lost; discs with audio, several tracks or Form 2 sectors are refused with a reason instead of mangled.
• Skipped jobs now say why. Files dropped on the exe or opened with "Open with" are loaded at startup.
• Tested on real discs: multi-track CDs (32, 11 and 2 tracks) were extracted with Automatic and rebuilt to CHDs with identical data checksums; a Dreamcast GD-ROM extracted into its own folder.

Updating: the in-app updater will offer this version (click the version button at the bottom of the window). Updates from 1.2.2 or newer restart cleanly.

Download CHD-Manager-1.4.0-win64.zip, unzip it anywhere, and run CHD Manager.exe. Windows 10/11, 64-bit. Python is not needed. Includes chdman 0.289.

Heads up: the exe is not code-signed, so Windows SmartScreen may show "unknown publisher" (choose More info, Run anyway), and some antivirus programs can be suspicious of packaged Python programs. You can also run CHD_Manager.pyw from source or build the exe yourself with build.ps1 (see the README).
