Its main benefit is its exceeding of the 4 GB file size limit, as file size references are stored with eight instead of four bytes, increasing the limit to 2 64 − 1 bytes. Microsoft's GUI and command-line format utilities offer it as an alternative to NTFS (and, for smaller partitions, to FAT16B and FAT32 ).
Note (7): When using a page size of 32 KB, and when BLOB/CLOB data is stored in the database file. Note (8): Java array size limit of 2,147,483,648 (2 31) objects per array applies. This limit applies to number of characters in names, rows per table, columns per table, and characters per CHAR/VARCHAR.
Files that were too large for 32-bit operating systems to handle came to be known as large files. While the limit was quite acceptable at a time when hard disks were smaller, the general increase in storage capacity combined with increased server and desktop file usage, especially for database and multimedia files, led to intense pressure for ...
HPFS (High Performance File System) is a file system created specifically for the OS/2 operating system to improve upon the limitations of the FAT file system. It was written by Gordon Letwin and others at Microsoft and added to OS/2 version 1.2 , at that time still a joint undertaking of Microsoft and IBM , and released in 1988.

Database maintenance includes backups, column statistics updates, and defragmentation of data inside the database files. [5] On a heavily used database, the transaction log grows rapidly. Transaction log entries must be removed from the log to make room for future entries. Frequent transaction log backups are smaller, so they interrupt database ...
