Only some archive files show thumbnails
Short fix: Confirm the archive contains supported image formats and is not encrypted.
- Supported archives:
.cbz/.cbr/.cb7, ZIP, RAR, 7z - Supported images: JPEG/PNG/GIF/BMP/TIFF/ICO + WebP + AVIF
If a specific archive fails, check the log for decoding errors.
WebP/AVIF thumbnails are missing or slow
Short fix: Update to the latest release and verify the archive entries are valid images.
WebP/AVIF decoding depends on the image crate and can fail with corrupted files.
Check %TEMP%\\cbxshell_debug.log for decoder errors.

Short fix: Run regsvr32 /u cbxshell.dll from an elevated command prompt.
