1:48:52mmozeiko Q: Are you sure always lowering filename to lowercase is a good solution? Because case-sensitivity is a feature of filesystem, not whole OS. On NTFS you can enable case-sensitivity individually per folder. You can mount NTFS disk on Linux / Mac. And on Apple HFS+ or APFS can be both - case sensitive or case insensitive, depends on how you format it
