Loading a file with a stream.

[Smiuv]

Hi, I wanted to know if when I read a file from a stream, it doesn't go into RAM all at once like a normal stream. For example, if I edit a 200 MB file, does the entire file go into RAM at the moment of editing?

Given you've not preloaded your entire file to a MemoryStream before feeding it to ATL, the answer is no.

That being said, under certain circumstances, ATL may load large chunks of your file into RAM during editing to optimize I/O performance.

If you have RAM issues, you can completely disable that behavior using Settings.ForceDiskIO.

What if I just load the file and don't do any editing? Just read some information from the file.

Then RAM usage will be limited to the absolute necessary. Expect very low usage by default.

Thanks.
