Boost C++ Libraries: Ticket #2725: boost::filesystem::exists throws on Windows if the drive letter doesn't exist

anonymous — Wed, 04 Feb 2009 15:34:56 GMT

Hello,

I have a correction to this issue. My invalid drive is actually a removable disk (USB) so actually the drive letter *does* exist but nothing is inserted. I suppose its therefore justified that an exception is thrown.

Yours,

David.

If the drive does not exist, then the file does not exist. Special cases are nice, but this function does not do the right thing when the drive does not exist. I don't see how the previous comment is relevant.

boost::filesystem::exists also throws if the drive is an empty CD/DVD drive.

I think it's reasonable to say that if the CD/DVD drive is empty then the file doesn't exist.

For an empty CD/DVD drive ec.value() == ERROR_NOT_READY

I can't reproduce the problem with v3 on the current trunk.

I've added a program, .../libs/filesystem/v3/example/file_status.cpp to the trunk. It can be built with bjam in that directory.

Please give it a try and send me the output if you are still having problems.
