FSPlugin development

[fabiochelly]

I try to create my first FS plugin.

Does any one know if it is possible to prevent the user to copy folders ? (I would like to authorize file copy only)

I don't know much about the plugininterface - but if your plugin get a filename for each entry selected by the user, you could manually check the file in your plugin.

Code: Select all

callback function that responds to copy command(..)
{
  FileDataType = openFile(..);
  if(FileDataType->isDirectory())
  {
    //don't copy - perhaps warn the user ?
  }
  else
  {
    doStuff();
  }
}

Actual implementation depends on language..

The problem is that I can't block the copy before it starts.

Yes you can! Implement the function FsStatusInfo. When it is called with FS_STATUS_START and FS_STATUS_OP_GET_MULTI, TC will start a download operation from your plugin. Now set a flag (e.g. incopy=TRUE), and if it is set, return 'no more files' when TC calls FsFindFirst! This prevents TC from listing subdirs during copy, and this way it cannot copy them. Don't forget to clear the flag on receiving FS_STATUS_END notification!

Thanks, it works fine.

Well, it works for the copy, but this method don't work for a FS_STATUS_OP_CALCSIZE.
I get an error (it seems to call findfirst many times then return an error)

Just handle FS_STATUS_OP_CALCSIZE in the same way as Christian it described it with the copy process (set a flag and when FNC is called return an invalid pointer and SetLastError to"no more files"...)

[fabiochelly]

That's exactly what I've done but if it works fine for a folder copy, I didn't get the same results for the CALCSIZE of a folder.

Thanks to everyone, I found where was the problem: I need to do the memset 0 to FindData even if I return an ERROR_NO_MORE_FILES
