We have a very large file, (over 1GB), that we want to place on the users system as part of the installation. We do not want to have the file copied in one piece as this will take some time, and the user may wonder if the install is broke.

Is there a free tool, that does not require a license, that we can use to first break up the file into smaller pieces, and then using this same tool as part of the installation, join\merge these files together on the users system? Some kind of command line tool.

It would be nice to, as the pieces were being joined, to show a scroll bar showing the percentage done. I assume that this would be a seperate process from the automatic IS file copys, (I would have to do some script).

At the same time, how can I flash different bit maps about the product, every ten seconds as the file copy\merge is happening.

Even if you can only answer one of the questions above, or, just point me in a dirrection, please do so.

As far as an InstallShield solution to your question, I am not sure. However nearly any compression program can do this for you : WinZip (http://www.winzip.com) | WinRar (http://www.rarlabs.com) as well as several others. All of them are free to use for a time. Any end-user can download a free copy from their respective sites. If you are looking to use it permanently yourself it is less than 30 dollars for a license for either one.

WinRar seems to be the method of choice as they see to have a higher compression ratio and are a little quicker on larger files. Winzip however has advanced security features. Both can be run from the command line.

Hope this helps.

Thanks for your reply.

We want to make the installation of the product as hassle free as possible, so telling the end users to download a product to put the pieces of the file together...is not an option.

Also paying for a license for each CD cut... is also too expense.

I will keep looking for a freebe.

Thanks again

Well, I had used a file splitter in the past, and it was freeware. So I went out to find it, and sure enough, it still is.

Here is the link to TC File Splitter (http://tcsoft.tingocreations.com/index.php?page=tcfs). This is a link directly to the download page where the info on the program is. The main page is in German, so I linked you to the other in case you weren't multi-lingual as well =). This file is opperable on the command line level.

Also, there is a site called freewarefiles.com. I personally have no experience with their site (other than I see that the file I just mentioned is hosted there as well) so I could not tell you the reliability of the other programs they have. Here is a direct link to the search results (http://www.freewarefiles.com/results.php?categoryid=9&subcategoryid=97) for the file splitters they host.

Again, I have no idea on the reliability or licenses of the other projects there. I know there used to be a few hosted on Sourceforge.net, but alas, they are no more.

Hopefully this post was a little more useful. I would have had this info earlier, but I was away when I replied the first time.
