The DT80 File System 
Internal File System (B:) 
The DT80 uses a Windows compatible FAT16/FAT32 file system for storing logged information (data and alarms) and 
system information. The internal file system uses flash memory, so all files will be preserved even if the DT80 is reset or 
loses all power. The size of this file system for a standard DT80 is 128Mbyte or the latest models have 2Gbyte storage. 
The internal file system is used to store information such as: 
•  program text for stored jobs (e.g. 
B:\JOBS\MYJOB\PROGRAM.DXC) 
•  store files (e.g. 
B:\JOBS\MYJOB\A\DATA_A.DBD) 
•  archive files (e.g. 
B:\JOBS\MYJOB\A\009_20100401T090002.DBD) 
•  other unload output files (e.g. 
B:\MYDATA\MYJOB\021_20100101T190012.CSV) 
•  current profile settings (
B:\INI\USER.INI) 
•  system event and/or error logs (
B:\EVENTS\EVENT.LOG and ERROR.LOG) 
•  documentation files (e.g. 
B:\DOC\DT8x Users Manual.pdf) 
•  dEX(web interface) Files (e.g. 
B:\WWW\indEX.html) 
Note: Path and file names shown above are for illustrative purposes only, and may change in future firmware revisions. 
A typical directory listing (see File Commands (P116)) of the internal file system might look like: 
  DIRTREE B: 
Volume in drive B has no label.

In this example there are three jobs stored on the DT80: SPARROW (one schedule; three archive files have been created 
at various times; in the case of the first one the store file was not yet full at the time it was created, hence its size is 
smaller than the others), UNTITLED (no schedules have logging enabled, hence no store files) and DTCAN169 (two 
schedules with logged data). 
External USB Devices (A:)  
An external USB memory device plugged into the DT80 can be used to store: 
•  store files (e.g. A:\SN081234\JOBS\MYJOB\A\DATA_A.DBD) for schedules that are configured to log 
directly to the USB device (using the 
"A:" schedule option) 
•  archive files (e.g. 
A:\SN081234\JOBS\MYJOB\A\001_20060401T090002.DBD) 
•  an ONINSERT job (A:\SN081234\ONINSERT.DXC) which will run when the memory device is inserted into 
this
 DT80 
•  an ONINSERT job (A:\ONINSERT.DXC) which will run when the memory device is inserted into any DT80 
•  other files which have been manually copied from the DT80, e.g. event logs 
•  other files not related to the DT80
