File formats
Each script, reading buffer, and saved setup is represented on a flash drive as a
separate file.
Directories on a flash drive used with the Series 3700 can only contain a limited
number of files. The top-level directory is limited to approximately 150 files, while
subdirectories are limited to approximately 500 files. Once the limit has been
reached, a "file system full" error message is generated.
Default file extensions
You must specify the full filename, including the extension, when sending
commands. Note, however, that the front panel automatically generates a
generic filename that you can use as a base for naming your files. Also, some
commands (for example, io.open (on page 9-13)) will work with either a
relative or absolute path to the current working directory.
The Series 3700 has the following set of default extensions:
.tsp (Test Script Processor for scripts
.csv (Comma Separated Values) for reading buffers
.set for saved setups
