composed of a management folder for saving of data files and index information for all
data files in the management folder. The management folder is at the following location.

Fle Import
Data files are copied to the management folder managed by DAQManager, and index
information is created. Import can be performed automatically or by manual operation.
Automatic import:
A specified folder is monitored periodically, and any not yet imported files are imported
automatically. A folder which is a monitoring object is called a watch folder. There is a
function for automatic import that automatically converts the files to Excel/text format.
The converted data is created in the folder containing the imported file.
Manual import:
A specified file or folder is acquired manually to the management area.
Please refer to the following for the approximate number of files which can be imported.
If a DX unit creates one file (a file with 10 alarms and 10 messages) per day, the files of
100 DX units for 2.7 years can be imported. Note that the number of importable files differs
depending on the set number of groups and channels. Importing from up to 300 instruments
is possible, but importing is not allowed if the file capacity reaches the upper limit.
Fle Export
Required files are copied out from the management area. The exported files can be
displayed with the viewer software of DAQSTANDARD or DAQEXPLORER
* of our
company.
* The DAQEXPLORER Viewer version 4.11 or before cannot display exported files of the
DX1000/DX1000N/DX2000 release number 4.
Fle Deleton

deleted data file is also deleted.
Data Backup
All data files and index information in the management folder are copied as backup data
to a specified folder. The file management information for backup data can be read and
restored by DAQManager.
