Unable to transform tables > 2GiB #2

Issue found user:

Hi,

I’m trying to use the transform tool to convert some JUNO/JADE data from PDS3 format to CSV. I was able to run the tool successfully on the low rate data, however, the tool failed on the high rate data (perhaps the data file is too large in size?). The file in question is (https://pds-ppi.igpp.ucla.edu/search/view/?f=null&id=pds://PPI/JNO-J_SW-JAD-3-CALIBRATED-V1.0/DATA/2016/2016240/ELECTRONS/JAD_L30_HRS_ELC_ALL_CNT_2016240_V01&o=1). When running the tool, I’m getting the output:

Possible clue towards solution:

Look into the following clue:

the transform program must load the number of bytes in the binary file as an integer. However, because the file size was too large, the integer overflowed and became negative. Changing the capacity variable to long int would likely solve this particular problem.
