how to increase the memory of VI?

Hello everyone,

I made a huge VI... Please find it in attachement.

I had given 3 file path, In raw data file path I have to attached the 165 kb file. And in remaining 2 file path I have to attached 1 kb file.

During running my VI the VI stops and showed the error that` VI memory is full ´´ and ``VI stops at Fract/String to Number on block diagram´´...

I eliminate unneccesory indicators but still the error is same, so I dont know how to overcome with this problem.

Thank You,
