File Time and Date
Similar to a computer file system, all files recorded by the 702T 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.

File Size Maximum
The CompactFlash card is formatted as a FAT32 volume. This structure allows for the CF cards to di-
rectly mount on common computer platforms, either using the units FireWire or from a card reader.
Using the FireWire connection the CompactFlash card in the 702T appears as an external FAT32
removable storage volume.
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 702T CF card, the largest any single file may be is 4 GB. The 702T automatically splits
audio files before the 4 GB size is reached and begins recording to a new file. When joined in an edit-
ing program, these files match seamlessly with no samples lost. The 702T has a 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 makes
