I have this function that should read a directory and pack all .dat files into a virtual zip file, and then upload it to my ftp server.
My resulting zip file does apear on the server, so it apear to work.

But I found there is a file named 0 that is created in the progdir every time the function runs, which is the same file as my uploaded zipfile.

Looking at my code, I found I must have made a copy/paste mistake when writing the line that defines the virtual file. (first line in the example code below) I figured I just needed to remove that part which says "statusfil$ =", but then it will not work at all.
The variable statusfil$ is used for something else another place in my script, but is unused at the time this code below is executed, so it contains Nil

What is

Why do you have two "=" characters here? Assigning a value into a variable will give 0 as the result of the assignment operation itself always (for example, DebugPrint(a = 3) would print "0" even though "a" gets assigned with "3"). So, the result from DefineVirtualFileFromString() will be assigned into the statusfil$ variable in this case, and the result of that assignment operation (0) will be placed into the brettarkiv$ variable.

zip.OpenArchive(1, brettarkiv$,#MODE_WRITE)

So, here brettarkiv$ is assigned with the value "0" and a new zip archive is created to a file named "0". All further file operations are made into this "0" file and the virtual file isn't used at all.

brettfil$ = brettmappe$.."/"..s$

Small tip, if you would use FullPath(brettmappe$, s$) then you don't have to handle the "/" manually and it's safer if your path happens to have / in it already.

If FindStr(brettfil$, ".dat")

This will take other than .dat files too, you'll have to do:
If FindStr(brettfil$, ".dat") > -1
or
If EndsWith(brettfil$, ".dat")


But about the main question... I'm not sure if virtual files can be used with the Zip plugin at all... you might need to use a temporary file for that.

It should not be there. That was why I wrote that I have done a copy/paste mistake without noticing.
But it does not work if I remove it, which might support your comment that zip files does not go with virtual files.

And thanks for your useful tips also.

Actually, virtual files should be working with zip.OpenArchive().
