Hi Chubler_XL,

I tried out your code snippet. There're a couple of observations that I made.

Firstly, the splitted files are being generated, but the sizelimit is not being considered as that in the parameter file, but the size of the initial file itself. For e.g., suppose the initial file ("output") was created with size 324010 bytes, whereas the parameter file specified the size limit of 10240 bytes. However there are two files created by the script, one is "output" (the initial file) with size 324010 bytes, and "output.2" with size 324017, both with the same data.

I guess there might be something amiss with the bytes variable assignment, but I'm not sure.

Secondly, just for my knowledge, is your script supposedly appending </URL> to the end of every file that gets generated?



Thanks,

- Avik
