File Renaming on Save and Extract
BetterZip 6 can apply a renaming transformation as files enter or leave an archive. Pick the mode in a save or extract preset and every file the preset handles gets the same treatment.
Available modes
The Rename items popup in a preset offers five choices:
- None: the default. Filenames pass through unchanged.
-
Sanitize filenames for Windows: replaces any of
< > " : / \ | * ?with an underscore so the archive (or the extracted files) won’t trip Windows file systems. -
Replace space with _:
my holiday photos.jpgbecomesmy_holiday_photos.jpg. Helpful for shell scripts, web servers, or any tool that’s awkward around spaces. -
Replace _ with space: the inverse.
my_holiday_photos.jpgbecomesmy holiday photos.jpg. -
Replace _ and . with space: same as above but also converts dots in the stem to spaces. The file extension is preserved, so
my.vacation.2026.jpgbecomesmy vacation 2026.jpg.
Where to configure
Choose the desired transformation in Settings > Presets. Both Save Presets and Extract Presets have a Rename items drop-down, so you can sanitize on the way into an archive or out.
Conflict handling
Renaming can produce duplicates: photo_1.jpg and photo 1.jpg collapse to the same name under “Replace _ with space”. When that happens during extract, the Conflict Resolution window steps in.
