Upper limit to FileRead?

[SlowCoder74]

What is the upper limit to [count] for the FileRead command?

Your question is too vague.

If you mean amount of data that can be read then I think there is 2 GB limit (probably depends on OS).

AutoIt3 FileRead Maximum

I get this thread, which links to another pertinent thread:

AutoIt may have updated in the meantime. But even so, it's probably better to process large files in chunks. Maybe make a call to get the file size first. Then decide how to process it.

We hit the limit some months ago. To sum it up: Theoretically the string to receive the bytes read by FileRead can contain up to 2GB of data. In practice the size is limited by the amount of contiguous storage that can be obtained from the operating system. This is usually between 200MB and 500MB.

So I would advise to read the file in chunks you can easily manage.
