Release Filee 1.10.4 · KnifeLemon/Filee

What's Changed

Remove background (issue #69, by @SeoJCalive). A new image option and built-in preset make a plain backdrop transparent: the paper behind a signature or stamp, the backdrop of a logo. Offline, with smooth edges and the ink colour kept, also on phone photos with uneven lighting. "Keep enclosed areas" keeps the inside of a logo. Formats without transparency (JPG) get the background colour instead. The preset is on the Presets page; add it to a donut in Settings → Toolbar.

Watch folders keep subfolders (issue #72, by @SeoJCalive). With "Include subfolders", files from Inbox\2025\scans now go to converted\2025\scans instead of all into converted (where files of the same name became a (2).pdf), the way originals are already moved. filee watch does the same.

Starting Filee again while it is still starting. Files opened from the right-click menu or Send To, or the installer's request to close Filee for an update, were lost when Filee took more than a few seconds to start (a slow or busy computer). They now wait until Filee is ready.
Security update. The .NET cryptography library PDFsharp uses (System.Security.Cryptography.Pkcs) is updated to 10.0.13, which fixes two denial-of-service advisories (CVE-2026-84008, CVE-2026-70162).

Version 1.10.4: later launches wait for Filee to start, Pkcs security update by @KnifeLemon in #75
자동 변환 폴더: 하위 폴더 구조를 변환 결과에도 유지 by @SeoJCalive in #73
이미지 배경 제거 기능 추가 by @SeoJCalive in #70
