Zmiany w wersji 0.62
- Features implemented or bugfix since V0.53:
- Ext4 extent writing support
- Size manipulation and i/o path revised for support of indirect and extent-based mappings
- 16T volume supported (tested and confirmed with 4T volume).Version 0.53 and previous versions only support up to 2T volume
- Deletion acceleration: truncation optimized for indirect-based files
- Size-expanding disabled in IRP_MJ_CREATE for better performance. Windows sometimes would truncate file size back to 0

- FIXME: Possible zero-content returned (requesting data from file tail)
- FIXME: File ByteOffset updated for FO_SYNCHRONOUS_IO open (async i/o)
