Partition a directory by size.

# split photos into 100mb-sized parts, but keep subfolders
part-dir ~/photos ~/photos-parts -s=100mb

# split videos into 1gb-sized parts, and also split subfolders
part-dir ~/videos ~/videos-parts -s=1gb -r

part-dir INPUT OUTPUT -s <size> [-r | --recurse] [-p | --pack <packing>]

INPUT: The directory to partition.
OUTPUT: The directory to copy parts to.
<size>: The size of each part, a number followed by a suffix:

• no suffix, or suffix b: in bytes
• suffix k or kb: in kilobytes
• suffix m or mb: in megabytes
• suffix g or gb: in gigabytes

recurse: If this flag is set, part-dir will also split up sub-directories.

<packing>: The packing option, higher levels may reduce the number of parts, and make part sizes closer the the maximum. Levels:

• none: no packing (default)
• normal: pack parts with items from other parts
• tight: sort parts by descending size before packing
