Local File Management
Captain EPM requires very little local storage footprint. All critical configurations, diagnostic caches, and secure credential storage are strictly isolated within your Windows user profile folder.
Primary Storage Location
All local data generated by Captain EPM is stored in the standard Windows local application data directory. This ensures that configuration does not bleed across multiple users sharing the same physical machine or virtual desktop.
Typically resolves to: C:\Users\YourUsername\AppData\Local\CaptainEPM\
File Types and Contents
AppSettings.json
Stores your UI preferences, theme settings, API endpoint URLs, and recent connections history. No passwords are ever saved in plain text within this file.
LocalCache.db / SQLite
A lightweight local SQLite database used to cache EPM metadata (dimension members, alias tables) to drastically speed up Excel performance. This file is routinely purged and rebuilt.
Diagnostic Logs (*.log)
Stored within the /Logs subdirectory. These files contain standard operational telemetry (e.g., "Failed to connect to API", "Timeout on job execution") to assist with IT support and troubleshooting.
Clean Uninstallation
Because Captain EPM isolates its data to the %LOCALAPPDATA% folder and does not pollute the Windows Registry with complex keys, uninstalling the Add-in natively cleans up the executable footprint. IT Administrators can simply delete the CaptainEPM AppData folder to perform a factory reset.
