Sequential file access and binary file access

[Guest]

Hi All,

I have a .txt file, whose contents need to be read and processed. Which
among the following is the best way to do it?

- Using Sequential file access functions (FileOpen, LineInput, etc)
- Using binary file access functions (File.Open, FileGet, etc)

Thanks,
kd

KD,

For me the best choise is not between them, that is the Streamreader, the
speed of a file on disk is never faster than that the disk, which is always
slower than your program, so for performance you should not look for this.

I hope this helps,

Hi Cor,

When should one use sequential file access and when to use binary acess to
read .txt files?

Thanks,

KD,

When all characters(bytes) are readable as txt file, you should in my
opinion never use the binary access.

However just my thought, I never tried it because I even don't think about
another way.
