JVC 30 GB Hard Drive Extensions

I have a JVC Camcorder, Model Everio GZ-MG37US, which uses a 30 GB hard drive.

On the hard drive, in the SD_VIDEO folder is another folder, PRG001.

Inside that folder, in addition to the .mod file, is a PRG001.PGI file and a .MOI file.

What are they?

Well, according to the site bellow, the .pgi file is a management file. More specifically,

“[0051] Next, the structure of management files (e.g. PRG001.PGI) in the user area is described. A management file shows the correspondence between the content files in the content folders and the Key&Rule Entry areas. Specifically, a management file in a content folder stores data specifying the local number of a Key&Rule Entry area that corresponds to the plurality of contents stored in the content folder, this being achieved by corresponding the number (i.e. 001, 002, and so on) of the content folder with the local number of the Key&Rule Entry area."
