STEPS TO REPRODUCE 1. Click on a site that accepts uploading files. 2. Have the desired files, and folders in the same place. 3. Press Ctrl+A to select all of the files. OBSERVED RESULT Ctrl+A selects all files and folders, which doesn't make sense for the file uploading mode of the file picker, requiring the user to manually de-select them and possibly stumbling upon Bug 498689 . EXPECTED RESULT Ctrl+A would cause all files to be selected, but not the folders because they can't be uploaded with the files, and folders are only there for navigational purposes. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.4.3 KDE Frameworks Version: 6.16.0 Qt Version: 6.9.1 Kernel Version: 6.15.9-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 8 × 11th Gen Intel® Core™ i5-11300H @ 3.10GHz Memory: 9 GB of RAM (8.1 GB usable) Graphics Processor 1: NVIDIA GeForce GTX 1650 Graphics Processor 2: Intel® Iris® Xe Graphics Manufacturer: LENOVO Product Name: 82MG System Version: IdeaPad Gaming 3 15IHU6 ADDITIONAL INFORMATION The Folder uploading mode is a separate thing, and it doesn't suffer from this issue.
While changing Ctrl+A to not really be "select all" might not be the ideal solution, I agree that something could be done here to allow the user to select all files but not folders.
I just noticed that even thought the folders are selected, it only uploads the selected files. So it's actually a visual bug.
