|
Hi Jarek,
what happens in terms of data storage if I make a single recording of big size (multiple GB) through XDFWriter? It seems to keep everything in main memory until the end, when it's written do disk all at once.
1)Will, at some point, memory be just full and either BioEra or Windows crash, or will Windows keep creating virtual memory to keep this from happening (in case you know)?
2)Is it possible to make XDF Writer write continously to its destination file in disk, to avoid ever-growing memory usage?
Thanks,
Marius

Memory (RAM) is NOT used for that, this file can be as large as needed. The data is cached on hard drive in another (hidden) file which is then used to create the final one.
We don't want to create a partial file, it would be unusable before the headers are updated, so we could end up with a corrupted file if the design was not properly finished/stopped. |
