v1.4.0

New name: bl-slim. It covers Borderlands 4 and Borderlands 3. The script finds which game you have (BL4, BL3 or both) and trims each one.

Unzip, double click bl-slim.cmd.

Borderlands 4 189 GB to 57 GB, Borderlands 3 96 GB to 53 GB.

Same behavior as v1.3.0. Only the names changed: bl4-slim.cmd is now bl-slim.cmd, bl4-slim.ps1 is now bl-slim.ps1.

v1.3.0: Borderlands 3

Borderlands 3 support. The script finds which game you have (BL4, BL3 or both) and trims each one.

Borderlands 4 189 GB to 57 GB, Borderlands 3 96 GB to 53 GB (about 30 GB voices and 13 GB old patch files).

BL3 files are locked with a key. The key is inside your own Borderlands3.exe, so the script reads it from there.
No key is included in this repo.

v1.2.6

English voice files are now always kept (the game seems to need them; one user got a required-content pop-up after keeping only Korean). Warns if English is already missing. README credits SolTeLu.

v1.2.5

Skips pak files the tool cannot read (for example a mod file) and lists them, instead of stopping with 'no pak footer'.

v1.2.4

Fixes 'Cannot find drive' when Steam still lists a library on a drive that is unplugged.

bl4-slim 1.2.3

Clear message if a game file path is longer than Windows allows. README now says -Scan makes and deletes one 8 MB test file.

bl4-slim 1.2.2

Clearer message if you run bl4-slim.cmd without unzipping, and for unknown flags.

bl4-slim 1.2.1

Fixes the 'Cannot bind argument to parameter Path because it is an empty string' error when the game folder sits directly under a drive, like D:\Borderlands 4.

bl4-slim 1.2.0

Keep more than one voice language, like -Keep "German,English(US)" or 1,3 in the menu.

bl4-slim 1.1.0

Shorter script, same behavior. Unzip, double click bl4-slim.cmd.
