About Portable:

The portable version of the program is made in VirtualBox 4.3.6.91406 Portable with clean Windows 7x32 on VMware ThinApp 5.2.0 Build 3231342 Portable by KpoJIuK
- using the standard Windows notepad.
Portable - made from: CDA to MP3 Converter 3.3 build 1228 RePack by KaktusTV, since the author did not consider it necessary to share the "medicine", but offered to do like the others - from the "repack", which was done. This is acceptable, since the "repack" is competently made, and there is no other option.
To the author of the "repack", thank you for the material for porting ( treatment, Russification).
Details not needed in portable software are cut out. Portable version - not updated. Lossless compression was applied, at the first start, give time to adapt the paths, the program did not start.
