Is the process reversable? (information) (enhancement requests)

[randombyt]

Hi,
I have a couple of questions .

1- Is the process reversible? Can we convert .gdi (output) back to .bin/.cue in its original condition without losing any information (SHA1/ checksums identical prior to conversion)?
2- Is the output (in .gdi) similar to Redump gdi (the standard they were using earlier)?

Thanks for the application, I have tested it on few .bin/ .cue files and its working correctly. Some requests:

1- It will be much easier if we can get an option to auto-name the output file to .cue name. i.e. "Pac-Man Adventures.cue" creates "Pac-Man Adventures.gdi"
2- Can you please add an option for batch application, with option to search in sub-folders?
3- If (2) is possible then a log file for any errors encountered.

Thanks.
