KillerShell

KillerShell puts a file browser, a terminal and a text editor in one window, on one tab strip and one set of keys, so you stop alt-tabbing.

Find a file, drop into PowerShell already standing in that folder, and open what you found, without leaving the window or reaching for a second app.

Search by filename wildcard or by line-by-line file content across any directory. Results stream in as they are found and nothing is indexed ahead of time, so there is no background service and no first-run wait.

The terminal runs PowerShell or cmd in a tab that opens in the folder you were just browsing. Your PowerShell $PROFILE is one action away from a menu, a right click, or Ctrl+comma, with both installed hosts listed so you never edit the wrong one.

The editor handles plain text with syntax highlighting for the formats field techs actually open: ps1, bat, cmd, reg, ini, conf, logs, markdown, JSON, XML, YAML and CSV. Encoding and line endings are preserved rather than invented, and both are shown, because a script PowerShell 5.1 will read depends on both.

Ships as a single portable executable, or install it for yourself or for all users. No runtime to chase, no account, no subscription, and no telemetry of any kind. Free and open source under GPLv3. Ten interface languages.
