[SOLVED] [HELP] Blocks, Column & Size ( .DAT ) What is Size?

[Ryan Hidayat]

Hello, i want to ask...

What is this?
And how to calculate?

i'v create my own Dat Editor with PHP...

Upload the .dat file and .strs > store it to mysql database > CRUD ( cread read update delete ) > export

and its works well, but i think that "Size" need to be sync when i create or deleting a row...

can someone explain how to calculate that "size" ?

Re: [HELP] Blocks, Column & Size ( .DAT ) What is Size?

The size column is the total amount of bytes in each block. In your screenshot, Your CashShop file should have exactly 240 bytes per block.

You should never need to change or recalculate this. This tells the server how many bytes to read when loading each block. If the size is changed the file won't load properly. Adding or deleting rows does not affect the block size at all.

Check your output file header and see what size you are generating compared to the original file. Your size will be incorrect if you are not writing the values back to the new file in the appropriate data formats.

Use a hex editor and hex compare the original file versus the new one. You will immediately see where you are writing the improper data and will be able to adjust your script accordingly.

Here is an example explanation on Exp.dat. Right click the image and open in a new tab to see the full size. RZ sucks at resizing images in posts.

That is correct. Bigger size = more bytes in the block = more columns.

You're welcome!

Good luck with the PHP editor project. I'm kind of curious about it so if you want to share some info feel free to PM me. I always like to see people working on something new.
