Object name restrictions on MinIO
Object names that contain characters ^*|\/&"; are unsupported on Windows and other file systems which do not support filenames with these characters. NOTE: This list is not an exhaustive, it depends on the operating system and filesystem under use.
For best experience we recommend that you use distributions that ship fairly recent Linux kernel such as CentOS 8, Ubuntu 18.04 LTS along with XFS as the choice for your backend filesystem.
