Solved win 7 windows explorer can't read directories that can be re

September 24, 2012 at 10:37:48
Specs: Windows 7, Core 2 dual

I have some files that I can read on windows XP. I put them on an external drive. When I connect this drive to a Win 7 machine I can copy the folders but I cannot see the files inside. If I open a folder in Win 7, Windows explorer will crash. Same thing happens when I use Win 7 Windows Explorer to look at the external drive folders.

If I put the external drive on a Win XP machine I can look at the folders and the files in the directory without any problems.

Turns out this is a file association problem with my installation of Win 7. I found that another Win 7 computer had no problem reading the disks. I found another post on the web that described the same problem I had and it indicated that ShellView could be used to repair the file association. I tried it and it worked.

What kind of files are contained within the folder(s)?

How long are the file names of said folders?

How big are the folders?

Just for fun, try copying the smallest folder across a network connection from an XP machine to a Windows 7 machine and then go check on the Windows 7 machine and see if there are still problems with the folder and it's contents.

They are .mat files which windows identifies as Microsoft Access Tables, so I would not expect any problems looking at the folders. The file names are short, not more the 8.3. The largest files are ~150Mb. Most are a lot smaller. I don't have access to network that has both XP and Win 7 machines on it.

It is very odd that you can't open them considering they're not big and the based on MS software.

Since you don't have a mixed network avaiable the only other thing I can think of to try off the top of my head would be to try using a different media. Perhaps it's the external drive that's the issue. If you have a big enough USB memory key, try putting on or two folders on it and see if you can't read them properly on the target PC. If you can, then maybe it is the external drive.

The data files are available on CD. Tried reading them with a Win 7 machine and the CDs showed blank. I was able to read the CDs using a Win XP machine. The CDs were originally created on a Win XP machine.

I don't think copying them to a USB device will help. The drive works fine with other files types (even multi-gig file sizes).

Hmmm....well, this is a puzzle to me. I've never run across this type of situation myself so I'm afraid I won't be of any further help. Here's hoping someone else has had this issue and can chime in here and point you in the right direction.
