I have a NTFS partition, that I previously used with a Windows machine. I installed ntfs-3g as a filesystem driver in CentOS, then mounted the drive. I copy the contents (cp) to a different NTFS partition, also mounted. Now, using
ll, I can see between the source and destination that some folders are 0 whereas the same folder on the other partition is (usually) 4096 bytes.
I never understood 'folder sizes'. Why does a folder have a size? And what do I lose if
ls -l reports to me that the folder sizes are different between a source and a backup (but files and file contents are without differences)?
