extract all files from compressed folder in xp 1

[SimonSellick]

Hi,

I hope this is a suitable forum to post this one.

Does the XP FileSystemObject (or any other object) support extracting the files from a compressed folder (which appears just to be a zip file) into uncompressed form? I can't see an obvious method in the object browser and I can't find a reference to doing this in msdn. I want to do this action in VB prior to processing the uncompressed files, so finding a suitable method would be preferable to having to shell out to some utility to do the extract.

Any help appreciated.

Simon.

One option (and the only one I know of) would be to use the winzip command line utility to extract to a temporary folder with a static name/location.

Then use FSO to loop through the folder, and delete the folder when finished.

Hope this helps,

Alex

I have been using this DLL for years and it has not let me down yet:

If you really want to do it using facilities built into XP try

http://www.mvps.org/emorcillo/en/code/vb6/index.shtml,

there is a class there that I have tried and it works. However its not any use unless running on XP; I personally use the free (and redistributable) zip and unzip exe files available from infozip

http://www.info-zip.org/

and shell out to them. The infozip dll referenced by Swi is another alternative, I prefer shelling out to the exes because they have more (command line) options than the dll.

HTH Hugh,

Alex, Swi, Hugh: Thanks very much for the links and suggestions. The files are very large so I've decided to go with the unzip.exe option and shell out to it - star for Hugh!

The info-zip DLL looks very interesting; I'll play with that as well when I get a chance.

Thanks again everyone.

Simon.
