Common Issues
:::details File won't import
"Unsupported format" error
- Verify file extension is one of the supported types
- Check that the file isn't corrupted
- Make sure archive contains image files, not documents
"Password protected" error
- Remove password protection using archive software on your computer
- Re-compress the files without a password
:::
:::details Pages appear out of order
Images inside archives should be named sequentially:
- Good:
001.jpg,002.jpg,003.jpg - Bad:
1.jpg,02.jpg,003.jpg
If pages are out of order, extract and re-compress with properly numbered files.
:::
:::details Large files are slow
For files over 200MB:
- Consider using OPDS servers to stream instead of importing locally
- Or convert to CB7 format for better compression
