Unexpected files

Hi

Here's a strange one...

One of the machines attached to our network (CAT5 cables, RJ45 connectors, TCP/IP, all machines connect via a hub), is a 486 running Win3.11 (Windows for Workgroups - 10 years old and still going strong!!). We use this machine for software that cannot be used on any later Windows version, and we also use it for digitizing drawings using an old version of one of our CAD packages.

After the drawings have been digitized we use WinFile (Windows file manager - the grandaddy of My Computer), to copy the drawings to our server (Dell Poweredge running Win2K Server and Small Business Server 2000). The files are copied into a shared folder. Now, viewing this location from the Win3.11 Winfile program we can see several files which have not been copied there. All the digitized drawing files are named using the 8.3 file format and generally follow the pattern - LHF4Pxxx.dc2 where xxx is the number of the drawing. However, the shared folder contains the dc2 files plus others named LHDAE5~1.dc2 etc. I created the shared folder yesterday and I know that no other data has been copied there.

When the same location is viewed from a Win98 machine these LHD files are not visible (My Computer is set to show all hidden files and folders). I even opened My Computer on the server and configured it to show hidden and system files, and these LHD files are still not visible. I have been able to use WinFile to copy one of these files from the shared folder on the server to my own computer and have also been able to open it up where it displays as a normal CAD drawing.

Does anyone know what is happening here?

Can you copy the file that you can see from the 2000 server to the Windows 3.11 box?

That would verify if that is a real hidden file.

I suspect it is just weird buggy code manifesting.

And a client of mine has a Radio Shack TRS 80 Model II that he keeps his business records on.

We should have a competition for the client with the world's oldest still criticial to daily business system.

Hi BFilmFan, thanks for answering. The only computer these files can be seen from is the Win3.1 machine. They cannot be seen when using the file server (Win2K server), a Win98 machine, a Win2K Pro, or a WinXP Pro machine. Even when the view settings on these machines are set to show hidden files and folders and to show protected OS files, these files are still not visible.

Hi, Sgt. Schulz, thanks for answering. All our systems can see and access data stored on the Win3.1 machine, though it can take a while... Also, the unexpected files are located on the share on the server only, they do not appear on the Win3.1 computer.

Have you tried opening any of the mysterious files in the shared folder? Does your drawing program have an autobackup feature where it saves files every few minutes to the HD in case of computer failure? From the name, they look like they could be temp files. When you copy the files over to the shared network folder, do you drag and drop them or do you move them using a path command?

Hi Myths, thanks for answering.

The strange files only appear on the share on the server after the original *.dc have been copied there. Files have a valid CAD extension, and I can copy them from the server to my own XP machine which sees them after they have been copied (I have to use the Win 3.11 machine to copy them). The program does not have an autosave feature.

The extension is not being changed - as you can see from the example I have quoted. What is especially odd is that the file names appear to have been lengthened.

Also, Myths, the files were copied using drag and drop...
