Copy files of specific type from parent to child folder
OS X uses HFS+, so you will need a program that will read HFS drives. The best free tool I can find is HFSExplorer. It's commonly used for:
A user of an Intel Mac running Windows with Boot Camp in need of accessing the files on the Mac OS X hard drive.
Owners of HFS+-formatted iPods, that wish to access their content from within Windows or elsewhere (a user emailed me and verified that this works).
Users of PearPC or similar Mac emulation/virtualization software that wish to access the contents of their virtual hard disks (will only work if the disk image is stored in raw format, as in PearPC).
People that need to access the contents of HFS+-formatted .dmg files.
It should let you rescue your files now.
There is also HFS for Windows and MacDrive, but they cost money. They both have free trials, which might let you rescue files.
