An old Ethereum backup may look like an unremarkable JSON file. The useful question is whether its contents describe an encrypted key, rather than whether the filename says Ethereum.
What an Ethereum keystore file usually looks like
- Folders literally named
keystore - JSON files with long structured content rather than casual notes
- Backups stored beside wallet setup notes, passwords, or seed phrase documents
- Archived folders copied from an old Windows user profile
Where to look on old Windows systems and backups
For a Geth installation, check %LOCALAPPDATA%\Ethereum\keystore in the old profile. A custom data directory can differ. Browser-wallet storage is a separate search; a JSON file’s presence alone does not establish usable keys.
Do not search only by coin name
keystore.jsonbackups in suspicious folders- Wallet export folders from desktop wallet migrations
- Browser profile folders that may contain extension wallet traces
- Notes, password hints, and seed-related documents stored nearby
How CryptoTrace helps with Ethereum searches
CryptoTrace can scan Windows folders, backups, browser-profile areas, and external drives for keystore-like artifacts and related wallet traces. It keeps the process local and read-only, which is exactly what you want when you are dealing with sensitive material and incomplete memory.
