Storage Settings

Rodel Reader's storage settings are located in Settings → General Settings, consisting mainly of library path management and log configuration.

Library Path

Library path settings show the current library location and provide two operations:

Operation	Description
Open in File Explorer	Open library directory in Windows Explorer
Switch Library	Return to startup page to select or create a library

Library Directory Structure

Each library contains the following structure:

Library Directory/
├── registry.db              # Service registry (core file)
├── secrets.db               # Secrets storage (API credentials, etc.)
├── Books/
│   └── <ServiceID>/
│       ├── books.db         # Book metadata
│       ├── covers/          # Cover images
│       └── files/           # Book files
├── Mangas/
│   └── <ServiceID>/
│       ├── mangas.db        # Comic metadata
│       ├── covers/          # Cover images
│       └── files/           # Comic files
└── Aggregator/
    └── <ServiceID>/
        ├── registry.db      # Data source registry
        └── datasources/     # Storage for each data source

Tip

registry.db is the library's core file, containing registration info for all service instances
Each service instance has its own subdirectory, using service ID as folder name
RSS and podcast services share the Aggregator directory

Switching Libraries

After clicking the switch library button, the app returns to the startup page:

Select Open Existing Library to switch to another library directory
Select Create New Library to create a brand new library

Note

Switching libraries does not delete current library data. You can switch back anytime.

Data Backup

Rodel Reader uses SQLite databases to store all data. Backup methods:

Manual Backup

Click Open in File Explorer in settings
Copy the entire library directory to a backup location
To restore, place the backup directory back or use "Open Existing Library" pointing to backup location

Key Files

File	Content	Importance
`registry.db`	Service registration info	Must backup
`secrets.db`	API keys and credentials	Backup if using sync services
`*/books.db`	Book metadata and reading progress	Recommended backup
`*/mangas.db`	Comic metadata and reading progress	Recommended backup
`*/covers/`	Cover images	Optional (can be regenerated)
`*/files/`	Locally stored files	Backup as needed

Log Settings

Log settings help troubleshoot issues and monitor app status:

Log Level

Level	Description	Use Case
Verbose	Record everything	Deep debugging
Debug	Record debug info	Development debugging
Information	Record general info	Daily use (default)
Warning	Record warnings and errors only	Low storage needs
Error	Record errors only	Minimal logging
Fatal	Record fatal errors only	Extreme cases

Tip

For daily use, keep the "Information" level. For troubleshooting, temporarily switch to "Debug" or "Verbose".

Log Retention Days

Set log file retention period (1-365 days). Log files exceeding retention period are automatically deleted.

Open Log Folder

Click this button to open the log directory in File Explorer. When contacting technical support, you can package and send log files.

Storage Cleanup

The app automatically cleans:

Orphaned service directories: Storage directories are automatically cleaned after deleting a service
Expired log files: Logs exceeding retention days are automatically deleted

Note

Automatic cleanup does not delete content in cover and file directories. To free up space, manually check these directories.

FAQ

Library file corrupted?

If registry.db is corrupted preventing library access:

Try opening another library or create a new one
Copy service subdirectories (e.g., Books/xxx/) from corrupted library to new library
Create corresponding service types in new library
Service data (books, progress, etc.) is preserved in subdirectory .db files

How to migrate to a new computer?

Copy the entire library directory to new computer
Install Rodel Reader
On first launch, select Open Existing Library
Select the copied library directory

Running out of storage space?

Check files/ directory for local files, delete unnecessary content
Reduce log retention days
Consider moving library to a larger disk
