Where Does GlassWire Store History and Settings?
GlassWire keeps network history in a ProgramData database, with settings and firewall profiles beside it.
Last updated
GlassWire records per app traffic into a database under ProgramData, which is why history survives reinstalls of the UI but vanishes on drive wipes. Firewall profiles and alert rules sit in the same service tree. The graphs you see are views over that database, not files per day.
That database grows with retention settings. Trim history length in settings before the drive fills. Back up the service data folder with the GlassWire service stopped, since live copies can split mid write and restore corrupt.
Where GlassWire stores this, by platform
C:\ProgramData\GlassWire
Service database plus settings inside. Exact interior may vary by version, check ProgramData if this does not match. Stop the service before copying for backup.
Frequently asked questions
How do I back up GlassWire history?
Stop the GlassWire service, copy the ProgramData GlassWire folder elsewhere, and restart. Restore by stopping the service, copying back, and starting it again.
Why is GlassWire using so much disk space?
Long traffic retention keeps every connection record. Shorten history in settings and clear old data, then watch the database shrink on next cleanup.
