I have a couple Spanish language web sites, so I was trying to come up with a Spanish language pack for Gallery.  I'm using version 3.01.00.  I was running the Resource File Verifier under Host:Languages, and under "English" the Gallery module produced errors of

Files With Duplicate Entries
Files With Missing Entries
Files With Obsolete Entries

all with the file

desktopmodules\Gallery\App_LocalResources\AlbumEdit.ascx.resx

As for what is Missing or Obsolete, I don't know enough to answer those questions, hopefully those with more experience can tell if those errors are important (it seems that the Downloads module produces the same errors).  As for Duplicates, the only thing I could find in AlbumEdit.ascx.resx were

 <data name="RootFolderDetails.Text ">
  <value>Root Album Content</value>
 </data>
 <data name="RootFolderDetails.Text">
  <value>Root Folder</value>
 </data>

the only difference between the two is that space at the end of the first entry.  Wasn't sure if anyone else had seen this before.

Seems like the Resource File Verifier is an interesting tool for module development even though it is placed under the Languages section.
