FileSize Function And Extended Paths

rmgregory243 · Post by **rmgregory243** » Sat Mar 30, 2024 7:07 am

In PureBasic 6.10 LTS beta 9 (Windows - x64), the FileSize function returns incorrect results when given a valid filename beginning with "\\?\".

? is not a valid character for filenames.

Extended-length path notation \\?\

@rmgregory243: I think it is not supported by the Pure Basic function.

Oh sorry, didn't know that. That's totally new for me.

I tested it with a few files and it seems to work fine for local disk files.
Note that the return value is a quad type.
Tested with 6.10 LTS x64/x86.

sz.q = FileSize("\\?\Z:\test.txt")

Same results as Breeze4Me. I tried \\?\c:\test.txt, \\?\c:\games\test.txt, and \\?\c:\games, all seemingly worked as expected.

Works here as well, do you have any more information ?
