7 Save/Recall/Print
7.1 Quick Save
If Quick Save is pressed after startup and before any qualified Save has been
performed, the Quick Save function performs a Screen Image save using the current
settings for Screen Image saves (current theme, current directory), which then
becomes the “last save” for the purpose of subsequent Quick Saves.
The Auto File Naming feature automatically generates a file name for use when
saving a file. The filename consists of a prefix and suffix separated by a dot, as is
standard for the Windows file system. A default prefix exists for each of the
available file types:

State_
(Save/Recall)
Trace + State

A four-digit number is appended to the prefix to create a unique file name. The
numbering sequence starts at 0000 within each Mode for each file type and updates
incrementally to 9999, then wraps to 0000 again. It remembers where it was
through a Mode Preset and when leaving and returning to the Mode. It is reset by
Restore Misc Defaults and Restore System Defaults and subsequent running of the
instrument application. So, for example, the first auto file name generated for State
files is State_0000.state. The next is State_0001, and so forth.
One of the key features of Auto File Name is that we guarantee that the Auto File
Name will never conflict with an existing file.The algorithm looks for the next
available number. If it gets to 9999, then it looks for holes. If it find no holes, that is
no more numbers are available, it gives an error.
For example, if when we get to State_0010.state there is already a State_0010.state
file in the current directory, it advances the counter to State_0011.state to ensure
that no conflict will exist (and then it verifies that State_0011.state also does not
exist in the current directory and advances again if it does, and so forth).
If you enter a file name for a given file type, then the prefix becomes the filename
you entered instead of the default prefix, followed by an underscore. The last four
letters (the suffix) are the 4-digit number.
For example, if you save a measurement results file as “fred.csv”, then the next
auto file name chosen for measurement results save will be fred_0000.csv.
NOTE
Although 0000 is used in the example above, the number that is used is actually
the current number in the Meas Results sequence, that is, the number that would
