Calculating file sizes

File size is limited by the restraints of the operating system (generally, 2 GB) and the available memory space on your hard drive or disk (depending to which you save the file).

Windows OS

Mac OS

Use the following equation to calculate the memory required for your acquisition:

 Memory required (bytes) = [(8C + 2A) x S x T] + 1 MB*

C = Number of calculation channels
A = Number of analog channels
S = Sample rate (samples/second)
T = Recording time (acquisition length)
* 1 MB = memory required to store file information
Journals, events, and other information are variable and will also require more disk space. Once analog channels are filtered or otherwise transformed, the required amount of storage will increase to 8 bytes per sample, identical to calculation channels. It is not possible to perform any transformations for acquisitions where converting analog channels to floating point will exceed 2 GB.

Refer to the software guide available under the program Help menu for setup and analysis guidelines when working with large files.
