how to delete a chunk of bytes in a binary file

Hi,

How can I delete a chunk of bytes in my binary files to decrease the size.
I read an write bytes from or to file in Stream.

I m not sure , i think you have to re-write the whole file.
read the whole file into an buffer / array. delete the chunk and write it back.
There may be some other solution.

Hi,
Have you tried inserting an EOF at the byte whenre you want to terminate the file?

Cheers.

PS - Hope your insertion of data is working :)

Hi,

How to insert an EOF to terninate the file?

After I deleted the data at a position, I removed the rest data to this position and then I call SetLength to set new file size.
Is there any other good methods?

thanks.
