How to open an AMP file?

[eswbitto]

I'm trying to review the file contents between 4.2.d CE and 4.2.f CE on the amp file for googledocs. I'm running into an issue where with 4.2.d (the version I'm using in production) is not saving back to Alfresco.

So what program would I use to open the amp file?

Any 'zip' tool.   7 zip.  Pkzip.   Etc.

Hmm…I tried jZip but it couldn't read the file format….I'll try 7zip and see how that goes…Thanks!
