The sort function reorders the list according to the rules you specify:

The filter allows you to narrow down your search to files in a specified state:
- All - Show all files
- Unread - Show files that have never been opened or are currently being read
- Read - Show files where all pages have been read (completed)
Switching the Number of Columns
You can adjust the number of PDF columns displayed on the screen to match your screen size and preferences.
Choose from 2 to 6 columns. The default is two columns.
Mark as Read/Unread
You can change a PDF's reading status:
- Long press a PDF file in Library view
- Tap Mark as read or Mark as unread in the menu that appears
Delete from Device
Some PDFs are large in file size. You can delete files directly from the Library screen:
- Long press a PDF file in Library view
- Tap Delete from device in the menu that appears
Deleting a file does not delete your reading history from your device. Your progress will be preserved if you import the same PDF again.
