Backups and wallet data

The recovery phrase​

The recovery phrase brings back everything that is on the blockchain, which is the balance. Keep it on paper. See Recovery phrase.

Export wallet data​

Settings › This wallet › Export wallet data saves the rest in one file, for example epic-history-mainnet-20260930.wfeh. On the phone, share it or save it to the device, and keep a copy off the phone, such as in email or cloud storage.

  • The file is encrypted under a key that comes from the wallet's recovery phrase. It can only be imported into the same wallet.
  • It holds no recovery words and cannot restore a wallet on its own.
  • Export CSV is something else: a readable list of payments for a spreadsheet. It is not encrypted and cannot be imported.

To bring the data back: restore the wallet from its recovery phrase first, then import the file. The wallet offers that right after a restore.

The wallet's files on the desktop​

The app keeps its wallets in its data folder: .epic_cash_desktop in your home folder (on Windows C:\Users\<name>\.epic_cash_desktop). Settings › This wallet › Wallet folder opens it. A copy of the folder is not a substitute for the recovery phrase: the phrase works when the files are lost.

Clean up old wallet folders​

Remove from list in Settings › All wallets takes a wallet off the list but leaves its folder on disk. To delete the folder:

  1. Open the data folder: Open folder next to Settings › This wallet › App files.
  2. Open wallets. Each added wallet has its own folder named by a long ID; the first wallet's folder is mainnet.
  3. To tell them apart, open an ID folder, then its mainnet folder, and read WALLET.txt.
  4. Make sure you have that wallet's recovery phrase written down, or that it holds no EPIC you want to keep.
  5. Close Epic Cash Desktop and delete that one ID folder. Leave mainnet, wallets.json and everything else as it is.
warning

Deleting a wallet folder without its recovery phrase loses the EPIC in it.

Versions before 26.10.16 kept their data in ~/.local/share/com.blacktyger.epicwallet on Linux and in %APPDATA%\com.blacktyger\EpicWallet on Windows. Once every wallet from there has been restored in the current app and shows its balance, that old folder can go too.
