Dear Maintainer, It was necessary to defragment a 2 Tb disk with 15,592,612 files. With a 32 Gb swap file, the computer froze somewhere at 9,000,000. With a 64 Gb swap file, the computer froze somewhere at 14,500,000. With a 94 Gb swap file, it finally ended normally without the computer freezing. It would like e4defrag to send a message about this when there is a lack of memory, give advice on how to overcome this problem, and not hang up the computer.
