[Kst] Importing extremely long files (>32 Bit)

[Ben Lewis]

Hi Gunter,

Kst is capable of loading much bigger data files than 3.8GB, so log as you have enough RAM.

When using the Data Wizard to load your data file try reading just a sub-section of your data. For 
example, in the Data Range section you can specify to start at sample 0 and read to sample 10000 (or 
some other number that does not max out your available RAM).

When your data is loaded you can step through to the next subsection by using the forward and back 
arrows. Kst will release the previous data from memory before loading the next set of sub-section data.

I hope this makes sense. If you still have trouble loading your file let me know.

Regards, Ben
