While there are several file systems available for Windows systems, the New Technology File System (NTFS) is the one used most widely today.Īmong the features of NTFS is the ability to restrict access using access control lists ( ACLs), which catalog each access control entry (ACE) that contain information about the user or group account and their access rights to an object, such as a file or a folder.

Here is Microsoft NTFS documentation.How permissions work on a Windows file server References: In the following question, the answers explain the meaning of the hardlink field in ls -l output, and they point out that it has more than one meaning, depending on the entry type, but no answer explicitly addresses NTFS. (I don't know about Windows.) Evidence: I deleted one of the directory entries (in Linux rm filename), and the used space reduced by exactly the size of the deleted file. Q: When I delete samplefile.jpg, either in Windows or Linux, will the file's data fail to delete, because the use count is non-zero? Answer: In Linux, the file's data deletes correctly. But I don't understand how that ties in with hardlink count or what NTFS mechanism DPP is using or whether Linux (fuse) is including other link types when it calculates hardlink count or whether I'm barking up completely the wrong tree.

So, DPP4 seems to be storing a reference to the original file, and NTFS (or Linux) is counting the reference as a hardlink. Saving a modified file with the same name (save) does not increase the hardlink count. samefile path-to-file/samplefile.jpgĪs far as I can tell, Canon's DPP4 software (Digital Photo Professional) has produced the files with hardlink count = 2, by modifying a file then save as or export. Size: 29496 Blocks: 64 IO Block: 4096 regular fileīut the filesystem contains no other directory entry referencing the same inode number (file id in NTFS) or the same length, evidenced by 'ls' and 'find' initiated from the filesystem root: $ ls -Rli. Example output from 'ls' and 'stat': $ ls -li | grep samplefile.jpgġ002 -rwxrwxrwx. I have an NTFS filesystem on an external hard disk that I use in Windows and Linux (fedora). Does NTFS count other link types with the same counter it uses for hardlinks? Or does Linux include other link types when it calculates hardlink count in an NTFS filesystem?
