A technique for handling stranded file opens for DCOM utility requests in a NSK. In one example embodiment, this is achieved by selecting a source file to be compressed in a disk by the DCOM utility. The source file includes one or more non-contiguous disk file extents and each non-contiguous disk file extent includes multiple blocks. A temporary file is then crated to copy the source file. The multiple blocks in a current non-contiguous disk file extent are then copied from the source file by the DCOM utility by transferring data to the disk as a function of a NSK net transfer data limit size. A current file descriptor of the source file is then stored in an offset field of the temporary file and a current value is then set in the offset field of a source file control block of the source file as a function of whether all of the multiple blocks in the current non-contiguous disk file extent were copied to the disk.
