A.Applications like Excel seem to complain about them being there.
B.Less likely to be confused will .dlv files during searches/purges
During the generation of files then obviously duplication of names can occur.
To avoid this the following convention is used:
"_nnn" will be appended to any duplicate filenames, to make them unique,
where nnn = 1 to 999. (If you run out numbers the export will fail, tidying up will
remedy the problem).
Generated names depend on whether a single item, or multiple items, are
selected for export:
11-6-3 Single Selections
If a single item is selected for export i.e. "Item3" in the root directory of
"MyData Set" then the following file will be generated:
MyData Set1999011214Item3.csv
11-6-4 Multiple Selections
On Interval Items
If a multiple selection of "on interval" items with the same interval is made then
the name of the parent directory will be used e.g. if the items live in "Group1"
the following file will be generated:
MyData Set1999011214Group1.csv
The file will contain a column for each item selected and they will share the
Date and Time fields.
If a multiple selection of "on interval" items, with different intervals is made
then any items with the same interval will be grouped together in the same file.
The same convention will be used as above except using the duplicate
filenames rules described above. If an item does not share any interval with
any other Item then its name will be used in the filename.
For example:
If Items "I1", "I2", "I3", "I4", "I5", "I6" are selected from Group1 of Data Set
MyData Set and Items "I1", "I3" & "I6" share intervals and "I2" and "I5" share a
different interval then the following files will be generated.
MyData Set1999011210Group1.csv contains "I1", "I3" &
"I6"
MyData Set1999011210Group1_1.csvcontains "I2" & "I5"
MyData Set1999011210I4.csvcontains "I4"
11-6-4-1 On Change Items
All on change items will have their own filename generated regardless of any
multiple selections made, because it is not possible to determine any common
time interval with these type of Items.
If a multiple selection of 'On Interval' and 'On Change' Items is made then the
above conventions still apply.
Note: The milliseconds field will only be valid for one of the Items, and should
therefore be filtered out for this type of grouping.
