Where Does 7-Zip Store Settings?
7-Zip files options and history in a registry key, with no INI or config file anywhere.
Last updated
7-Zip is registry only by long standing design. Options, history, and interface state live under HKCU Software 7-Zip with no file alternative offered.
Migration means one registry export, merging cleanly without elevation. The key is small enough to eyeball before importing. Uninstalls traditionally leave the key behind, so fresh installs sometimes inherit ancient preferences.
Where 7-Zip stores this, by platform
HKEY_CURRENT_USER\SOFTWARE\7-Zip
Options and history live here. Export the key for migration; no config file alternative exists.
Frequently asked questions
How do I migrate settings?
Export HKCU Software 7-Zip to a .reg file and merge it on the new machine. History lists, codecs, and options travel together. Elevation is unnecessary since the key lives in current user.
What about portable builds?
The file manager panels read the same registry branch on launch. Plugin DLLs beside the exe add formats without configuration. Portable builds share the host registry like installed ones.
