[strange bug] File not found

[bobby]

I've got a strange error, or should I say, strange file.
The file isn't viewable in Explorer, and I can't delete it in TC.
Take look at the shoot:

Deleting the whole folder also don't works.

Any suggestion?

Hi,

It don't know what to do - but here is an explanation:

the problem is the period at the end of the filename:

Do not end a file or directory name with a trailing space or a period. Although the underlying file system may support such names, the operating system does not.

(Source: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/fs/naming_a_file.asp )

Windows provides file creation operations which may create filenames with a trailing period but other windows operating systems don't support such names.

Hi,
I'm aware of the case, and why the file isn't deleted, or displayed in Explorer, but I can't get why and how the file is created.
I have try to make such file, in order to confirm the theory that Im guilty for existence of such file on my HDD, but I didn't succed to rename any other file in such maner.
I'v made a text file, and tryed to remove the extension from TC and Explrorer - the trailing dot was deleted automaticaly.
I'v tryed to add a dot to the file name, to add more dots etc. - nothing, all the files was posible to delete. Except of the one on screenshot.

Anyone with an idea how to delete it?

Edit: I'm a programer, but this file isn't a product of any of my (badly writen) programs. Probably is a product of Mozilla download.

It's quite simple, I think. Create a button with "cm_SwitchLongNames" and let TC display the old 8.3 name of the file. Then you should be able to delete the file. At least does this work for me fine in any case (even to switch into unicode-named subfolder etc.)

Maybe this file has been created by unpacking a unix-archive? That way you can create those forbidden filenames.

Here is a small program capable of creating such files

www.lefteous.de/tc/archives/eviltouch/eviltouch.zip

Pass the filename as command line parameter.

Hi Lefteous,

this program does make nothing on my PC. Neither on the commandline nor called via button.
If I would not know (you) better I'd suspect it to be a kind of Malware .

But to let everyone know. I'm sure it is not.

Have you tried to pass a filename as parameter as mentioned above?

Of course it is malware if you know how to use it properly

[Sheepdog]

Yep, like

Code: Select all

EvilTouch.exe "ABD."

. Do you need .Net or anyxthing installed?

No prerequirements but a full pathname should do the job:
EvilTouch.exe C:\Nonsense\Hansi.

Source code:

Code: Select all

#include <windows.h>
#include <strsafe.h>

int APIENTRY wWinMain(HINSTANCE, HINSTANCE, wchar_t* lpCmdLine,int)
{
	const int MAX_NTFS_PATH = 0x7FFF;
	wchar_t fileName[MAX_NTFS_PATH] = {0};
	StringCchCopyW (fileName, MAX_NTFS_PATH, L"\\\\\?\\");
	StringCchCatW (fileName, MAX_NTFS_PATH, lpCmdLine);
	HANDLE hFile = CreateFileW (fileName, FILE_ALL_ACCESS, FILE_SHARE_WRITE, NULL, CREATE_NEW, FILE_ATTRIBUTE_NORMAL, NULL);
	CloseHandle (hFile);
    return 0;
}

It is known problem - and there is a way to solve it. Just run from command line the following command (I used the path that is on your TC screenshot):
del \\.\C:\Downloads\*

[bobby]

@Flint
That didn't help
File is stil there.

@sheepdog
that did the trick

Okay it works.
It does not accept quotation marks ( wich I tried for a filename with trailing space). But since I don't need a tool to create filenames that couldn be manipulated anymore it is not neccesary to adopt your tool.



But now I have tested that you can manipulate the file with TC in 'short names mode'.

That's strange... Can you post here the output text when you executed this command?

[bobby]

There was a question like "Are you sure Y/N?"
I'v typed Y.
Other file in folder was deleted, but the problematic one wasn't.
There was no error messages, I've got the prompt after typing Y.

The correct command line to delete these files is like that:
del \\?\X:\path\to\funnyfilename. (or more dots, * will delete all(!) files in that directory, so beware...).

It's better to create a button and drag and drop the files one by one to not nuke half of your file system by mistake.

Code: Select all

command: %comspec% /c
parameter: del \\?\%P%N
