I've seen this topic covered elsewhere, but the recommended solutions didn't work for me.

Problem - *some* of my RMP purchases filed in "My Library" for use in DAZ cannot be located in the program.  These are native DAZ format purchases, but DAZ cannot find them in the Library. 

Previous instructions I received from DAZ support are:

1) Open Daz Studio
 
2) Go to Edit (at the top of Daz Studio)
 
3) Click Preferences.
 
4) Click on the Content tab.
 
4) Click the bottom button "Content Directory Manager"
 
5) Select Other Import Formats. You'll know it's selected because there will be an orange outline around it.
 
6) Click the "Add" button on the left under directory. Browse to the Installation path and click Select Folder.
 
7) Click Accept in the Content Directory Manager and restart Daz Studio.

I've followed all this to the letter, but still several RMP purchases just don't show up in My Library.  I am running Windows 11, and DS 4.2.1.  It's inexplicable that most of my content filed here works fine, but other content from the same vendor and filed in the same location just doesn't show up no matter what.  Am I interpreting the instructions incorrectly?  When I browse to the installation path as described,  I am browsing to "My Library" and not any subdirectory.

Should I just add the missing items to a completely new directory, and try mapping to that?
