Manager uses SQLite databases, which are generally robust but can become corrupted due to hardware malfunctions or rogue programs.
The easiest way to manually recover a corrupt database is using the Command Line Interface (CLI) for SQLite. The CLI is a program named sqlite3.
This guide will walk you through the process of recovering a corrupt database file.
Download SQLite CLI from the [SQLite Download page](https://www.sqlite.org/download.html).
Download the precompiled binaries for your operating system:
• For Windows, look for sqlite — tools — win — x64 — .zip
• For macOS, look for sqlite — tools — osx — x64 — .zip
• For Linux, look for sqlite — tools — linux — x64 — .zip
Extract the contents of the downloaded zip file into a new folder.
Copy your corrupted SQLite database into the folder with the unzipped contents.
Rename your .manager file to corrupted.manager.
Open a command line interface (Command Prompt on Windows, Terminal on macOS/Linux).
Navigate to the folder containing the sqlite3 executable and the corrupted.manager file.
Run the following command to attempt recovery:
sqlite3 corrupted.manager ".recover" | sqlite3 new.manager
After the recovery command completes, you will have a new file named new.manager.
Import new.manager back into Manager and attempt to open it.
