File Time and Date
Similar to a computer file system, all files recorded by the 722 are stamped with the time and date of
file generation. To ensure that accurate time-of-day and file generation dates are written for each file,
make certain that the time-of-day clock and calendar are accurately set.
1. Enter the TIME/DATE: Set menu.
2. Set the current time and date using the navigation below.

Once set, the time and date clock will be kept while the removable rechargeable battery is attached.
If it is removed the internal AA NiMH time-of-day battery maintains the date for up to 5 days.
File Size Maximum
The 722 data volumes (internal hard drive and CF) are formatted and write to FAT32 file structures.
This structure allows these drives to directly mount in a wide variety of computer platforms, includ-
ing Windows, Mac OS, and Linux. Using the FireWire connection both internal drives (internal hard
drive and CF) appear as external FAT32 volumes.
Windows XP has a limitation on FAT32 drive formatting; XP can format a FAT32 volume to a maximum
of 32 GB, however it can read FAT32 volumes as large as 2 TB.
FAT32 has a maximum file size limitation of 4 GB. While it is possible to have thousands of files on
the 722 medium(s), the largest any single file may be is 4 GB. The 722 automatically splits an au-
dio file before the 4 GB size is reached and begins writing to a new file. When joined in an editing
program, these files match seamlessly with no samples lost. The 722 has menu-selectable file size
maximums of 512 MB, 1 GB, 2 GB, and 4 GB. The factory default setting for maximum file size is 2
GB. Some applications will not properly import audio files above 2 GB. The 512 MB size allows the
user to break an audio program into CD-R sized files for backup to inexpensive CD-R medium.
