What is Ext4 block size?
The normal block size used by ext4 is 4kb, or 8 of these “blocks”. That means that the space used by a file on ext4 must be an integer multiple of 8 “blocks”, and so the smallest size used by any file less than or equal to 4096 bytes in size is 8 512 byte blocks.
What is block size in IP address?
This is called the “block size,” because it refers to the size of the subnet blocks into which the network has been divided.

What is the default file size in Linux?
Linux HandbookAbhishek Prakash By default, the block size in most Linux system is 4096 Bytes or 4 KB. A directory in Linux is simply a file with the information about the memory location of all the files in it. You can force ls command to display file size in MB with the –block-size flag.
How to display file size in MB using ls command in Linux?
A directory in Linux is simply a file with the information about the memory location of all the files in it. You can force ls command to display file size in MB with the –block-size flag. ls -l –block-size=M. The problem with this approach is that all the files with size less than 1 MB will also be displayed with file size 1 MB.
