I think I've found a bug in PureZIP for PB4.
When I run this code

OpenConsole()

MyZIP.s = "C:\TestFile.zip"
Path.s  = "C:\Picasa2\*.*"

If PureZIP_Archive_Create(MyZIP.s, #APPEND_STATUS_CREATE)
  PrintN("Compressing files, please wait...")
  PrintN("")

  PureZIP_AddFiles(MyZIP.s, Path.s, #PureZIP_StorePathRelative, #PureZIP_Recursive)

  PureZIP_Archive_Close()
  PrintN("")
  PrintN("Compression completed!")
EndIf

PrintN("Archive contains "+Str(PureZIP_GetFileCount(MyZIP.s))+" files.")

PrintN("")
PrintN("Press any key to exit!")
Input()

CloseConsole()

All files in the Picasa folder is compressed along with the subfolders and files. One thing I notices is that in every folder below the root of the archive there is an empty file, with no name. I can't open the file in the archive, but it says it is 0 bytes uncompressed when I open it in WinRAR, compressed the file is 2 bytes.

When I compress a folder containing 34 files and 5 folders, PureZIP_GetFileCount reports it compressed 40 files. Is that the extra empty file it's counting?

Any feedback on this?

1. You don't need PureZIP_Archive_Create() / PureZIP_Archive_Close() when you use PureZIP_AddFiles(). Use these functions with the other PureZIP_Archive_* functions.

2. These empty files you see if you are using another archiver are a (dumb) workaround to add empty directories to the archive when using PureZIP_AddFiles(). It may look strange in another archiver but unpacks without any problem.

3. I don't know how to add empty directories otherwise (user wish) : I will make it optional.

4. PureZIP_GetFileCount() is only a wrapper for ZLIB function unzGetGlobalInfo().
