Strange CopyFile API
Hi. Developers. CopyFile API is strange. CopyFile API correctly read/write tow big files. But too small file(< 256Byte) is not read from source file and write distination file. When does API read? What is read's IRP?

Re: Strange CopyFile API
That is because the data of small file is residented in its File Record directly. and the system doesn't allocate another disk space for it. ----- Original Message ----- From: "$BEOJULP><(B" <xxxxx@hh.iij4u.or.jp> To: "File Systems Developers" <xxxxx@lists.osr.com> Sent: Thursday, March 16, 2000 9:30 PM Subject: [ntfsd] Strange CopyFile API > Hi.

Thank for your advice. How do I modify read data? weafon wrote: > That is because the data of small file is residented in its File Record > directly. > and the system doesn't allocate another disk space for it. >
