File types not recognized do not show up in the file viewer, although all folders are viewable.
File detail is shown at the right side of the display. The center divider points to the file selected for
information viewing. Information shown includes:
• file creation date, file flag (archive) bit status, checked means the file archive bit is set, clear
means the file archive bit is cleared
• file creation time, file size
• number of tracks, bit depth, sampling rate
• beginning ( BEG) time code stamp of the file
• There is additional information available. Pushing the Rotary Switch will cycle through the be-
ginning time code stamp (BEG), file length (LEN) user bits (USR), and frames per second (FPS).
The file viewer always exits to the main screen whether entered from the menus or the HDD key.
File Time and Date
Similar to a computer file system, all files recorded by the 744T 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.
File time and date and time code are unrelated.
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 code battery maintains the time-of-day and date for 8
days, or more.
File Size Maximum
The 744T storage volumes (internal hard drive, CF, external drives) are formatted and write to FAT32
file structures. This structure allows these drives to directly mount in a wide variety of computer
platforms, including Windows and Mac OS. Using the FireWire connection both internal drives (in-
ternal 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 individual file size limitation of 4 GB. While it is possible to have thousands
of files on the 744T storage volume(s), the largest any single file may be is 4 GB. The 744T automati-
cally splits an audio 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 744T has menu-select-
able 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
