7-zip error - Not supported archive

I have a batch file to extract zip file using 7-zip.  The command is follows:
U:\D-Database\0-script\7z e *.zip
7z.exe and *.zip file exist in 0-script folder.  U:\ is my mapped drive.  If I run the same batch on C:\, it works fine.  If I right click on zip file on U:\, and manually extract the file, it works.  However, if I run the batch on mapped drive U:\, I get an error and can't extract file.  I put "Pause" clause to see the error message and it was "Not supported archieve."  Does anybody have any idea?
My computer is XP sp2 and mapped drive is located on Windows 2003 Server.
I appreciate your any suggestions in advance.  Thank you.  hb

Hi, does it make any difference if you do this in your batch file:

U:
CD U:\D-Database\0-script
7z e *.zip


Or

U:\D-Database\0-script\7z e U:\D-Database\0-script\*.zip

Regards,

Rob.

Hiya

Have you tried:

[echo password >] runas [/user:administrator] [command]
as in
echo psw >runas /user:administrator u:\D-Database\0-script\7z e u:\D-Database\0-script\*.zip
 
*not forgeting to replace 'psw' with the administrator's proper password of course!
*if you omit the 'echo psw >' then you'll be promted for the password

Thank you to both RobSampson and t0t0.  I tried both suggestions, but it did not work.  The error message I get is:  (I added "pause" to see the error.)

U:\D-Database\0-script\7z e U:\D-Database\0-script\*.zip

7-Zip 4.42  Copyright (c) 1999-2006 Igor Pavlov  2006-05-14

Processing archive: U:\D-Database\0-script\*.zip

Error: U:\D-Database\0-script\*.zip is not supported archive

U:\D-Database\0-script\>pause
Press any key to continue . . .

I don't need to stick with 7zip.  Since XP comes with Compress Zip function, can I use this instead?  I appreciate your time and suggestions very much.  Thank you.

Try using  Windows' compression....

That's what I was thinking, too.  But how can I make a batch file, so that I do not need to manually process (unzip) file?  Thank you very much.

Hi, you can try the UltimateZip Command Line tool.  I gave an example of using it here:

If you intend using a zip compression program then I urge you to check out FreeByte's Zip at:

http://www.freebyte.com/fbzip/

It has a Windows' GUI as well as command line functionality and is fully compatible with XP's NTFS.

Picozip is another that springs to my mind although I haven't used it myself personally.

Once you have decided which zip compression program you want to stick with then you'll need to determine what the command line options are before embarking on writing any batch file.

I am pleased you were able to find the solution to your problem. Sometimes the solution is surprisingly unexpected.

No problem. Thanks for the grade. Perhaps 7-zip just lost its file type associations.....

Good work.
