What’s The Best Cross-Platform File System for external SSD/HD

[osculum_est_mortis]

I use linux/windows/Mac OS and its very annoying having encrypted drives that don't work with each other unless I use veracrypt or boot into a VM to unlock one another ... time consuming and just a pain .
wondering if there is a way so solve this ? can I unlock LUKS on Mac ? or unlock APFS encrypted Mac on linux ? vice versa
is there a file system that will work with encryption for cross platform without having to use veracrypt ??

found this from 2012 not sure if its still relevent

FAT32 Cross-Platform File System​

Advantages:

• Works natively and perfectly in all three operating systems.

Disadvantages:

• No journalling.
• Relatively low maximum partition size (2 Terabytes – not attainable yet but will be).
• Inefficient at large partition sizes.
• Maximum file size limited at 4GB.

NTFS​

Advantages:

• Works natively and perfectly in Windows.
• Other operating systems support read support natively.
• Robust and journalled.
• Very high limits on maximum partition size
• Very high limits on maximum file size.
• Generally efficient at large partition sizes.

Disadvantages:

• Requires third party software to allow for write support on Linux and Mac OS X.
• Slower on Linux and Mac OS X because of the use of FUSE.
• Proprietary filesystem patented, and at the whim of, Microsoft.

Ext3 – Cross-Platform File System​

Advantages:

• Works natively and perfectly on Linux.
• Generally fast, journalled filesystem.
• High file and partition size limits.

Disadvantages:

• Requires third party software to allow for any access under Windows or Mac OS X.
• Third party software tends only to support ext2 resulting in extra file system checks (and these are slow).

HFS+​

Advantages:

• Works natively and perfectly on Mac OS X.
• Works natively and perfectly on Linux (without journalling)
• Generally fast, journalled file system (but journalling must be disabled for Linux)
• High file and partition size limit

Disadvantages:

• Requires third party software to allow for any access under Windows.
• Linux access requires disabling journalling.
• Free HFSExplorer is not integrated into the Windows explorer.
• Commercial MacDrive (with full Windows explorer integration) is not free of charge.

I’d say use ExFAT. I suppose you could use VeraCrypt for encryption.

ExFat would be my choice also. The only disadvantage with exFAT is that like all other FAT files systems it's non journaled.

Paragon will sell you read/write APFS support for about $80 for both Linux and Windows. Check it out here: https://www.paragon-software.com/us/home/apfs-linux/

Unfortunately it looks like they don't support writing to encrypted APFS volumes.

its unusual that this file system doesn't exist. when it should. ??

You can use Paragon to write to NTFS on Mac OS. I'm not sure if it's encrypted.
