UNC Path bug ?

Hi,

When I try to create a file on windows 98 like this:

C:\\TEST.ZIP

It says:

'Cannot create file C:\\TEST1.ZIP.'

Partitions are FAT and FAT32

( It does work on windows xp with ntfs and fat32 )

I decided to post it in this newsgroup since it seemed the most suited...
there is no windows98.bugs newsgroup... and I accidently discovered this bug
when trying to save the file to a root folder. Because the way the string
was build it accidently created to slashes... this should however still work
since this conforms to UNC path standard.

( Delphi related )

case1: ExtractFileDir( 'c:\test\test.zip' ) would return 'c:\test' without
slash
case2: ExtractFileDir( 'c:\test.zip' ) would return 'c:\' with slash

The new string would be
case 1: 'c:\test' + '\' + 'test.zip' = 'c:\test\test.zip'
case 2: 'c:\' + '\' + 'test.zip' = 'c:\\test.zip'

So by accident I discovered this.

However case 2 should still work... it does on Windows XP but not on Windows
98

Hmmm

I could easily solve the problem by using ExtractFilePath which always
returns a slash at the end... at least it should if it doesn't I would be
more screwed

Then I would just code:

FilePath + FileName

'c:\' + 'test.zip' = 'c:\test.zip'

However this does not conform with UNC path standard...

The question would be: 'How long will microsoft tolerate
C:\FOLDER\FILENAME.EXT format ?'

I hope the answer would be: 'Forever'

Can't hurt to have some flexiblity

I would ofcourse be still screwed if some other functions would return C:
only without slash

Hmmm, nasty..

Maybe I should just make a (stupid) parse... I-don't-like-parsers.

Or maybe microsoft should make a parser for me =D

Like IsFileNameValid

If it's not valid... what then ? How do I correct it... I still have a
problem then...

Oh well, time to go...

Bye,
Skybuck.

This isn't a valid unc path. This is a drive path with an extra (and
erroneous) whack ("\") in it.

Thanks for pointing out my mistake.

It makes sense now:

unc path is:

\\<server name>\folder

My wacked brain read:

<drive>\\<folder>\<file name>

Funny.

unc paths are apperently about server stuff... not really drives

reminds me of

http:\\www.blabla.com\blabla.html.
