FAT32 is the current usual but "future *has been*" portable filesystem. FAT32 doesn't allocate partial blocks, so a direct copy of some linux directory often results in a very large loss of free space on FAT32. FAT32 limits you to files under 4GB, and partitions under 32GB. You can create a FAT32 filesystem with smaller allocation units, but that probably reduces the partition size limit and many not be supported on some devices. When moving files between linux and other systems I generally use archives to preserve ownership and permissions, while avoiding small file allocation problems. The way forward is exFAT: https://fossbytes.com/linux-5-7-microsofts-exfat-driver-code/ TL;DNR: exFAT is a patented Microsoft filesystem that is widely used for with removable storage on portable devices. Microsoft released a snapshop of the code under GPL2 in 2019. exFAT has total filesystem size and file size limits far beyond what most users require, and has been supported on Windows and macOS for years. Support for exFAT was added to the linux 5.4 kernel and Samsung (which has exFAT for androids device) has contributed improvements that were accepted for 5.7. Fedora 31 and 32 don't have exFAT in the kernel: % grep EXFAT /boot/config-`uname -r` # CONFIG_STAGING_EXFAT_FS is not set For now, there is a FUSE implementation in Fedora: % sudo dnf install exfat-utils fuse-exfat I generally format memory sticks/cards with Windows in case fuse-exfat does something that other devices don't handle. There are many 3rd party implementations; most are only tested against Windows. -- George N. White III
