How to merge two files on NTFS chaining the file's btrees nodes to avoid reading any file












2















I have the following challenge:



File1 is a huge file, let's say the filesystem assigns it filesystem disk blocks [1,2,5]



File2 is another huge file, let's say filesystem assigns it filesystem disk blocks [10,15,16,18]



Traditional append opens File2 and copies it to the end of File1, so it ends like



File1: [1,2,5],[30,20,40,182] (it assigns and copies File2 blocks in new ones)



File2: [10,15,16,18] (Will still be in use and assigned to File2)



I want to merge the two files without ever reading the files, let's say, getting File1 chain and consume File2, so it ends up



File1: [1,2,5],[10,15,16,18] (and File2 gets consumed in the process)



Do you know any API call to do that magic?



Thank you!
