Lacerta M-Gen User Manual page 34

The files in the list are ordered by their unique ID. This value is constantly increasing
with every new file creation and gives the ability to indentify all new files from the older ones
(from even those that were downloaded to PC and then deleted). The newest file is always the
first file in the list (at the top of the other) regardless to its creation time value.
When there is no open file:
..and there is space for a new one, the first line will be "create new", which will create
and open a brand new file by activating it (pressing SET if selected). This case is shown at the
screenshot. After a new file has been created the device exits the filesystem screen.
If there is no more space (free entry) for a new file, this option will be missing.
The "last opened" flag ("L") can be used to identify which file has been used previously.
If the device was turned off and then on, open this file to continue data storage into a single
file. (It as advised to use one file for each night if possible.)
If a file entry's row is selected the following options appear for the
buttons:
 SET button: display the file's details (new screen)
 LEFT button: delete the file (with confirmation). This
question is shown:
With pressing SET You can confirm
the deletion while ESC cancels it.
If there is an open file:
...then this screen at right can be seen, there is no "create new"
option. The "OP" ("open") flag shows which file is currently open. The
open file can't be deleted at this moment but the others can.
File details screen:
To see the details about a file press SET on it in the files list screen.
An example of the details screen is shown at right. The displayed data is
the following:
 State: the actual state of the file that can be:
o last opened: this file was opened last time (currently there is no open);
o OPEN: this is the currently opened file;
o closed: the file is closed (and so can be continued / reopened);
o broken: the file's data is broken, can not be continued / reopened.
 Creat: the date and time of its creation.
 Modif: the date and time of its last opening ("modification"). If this row is empty
the file was open (created) only once yet.
