When I compress a .flac to .zip and then uncompress to .flac again for moving and uploading purposes, will it be changed in any way?

I am a 1:1 Nazi so were talking perfection here...............

There will be no change at all in the any of the contents of the zip file.

Not unless something goes wrong, no.

thanks guys

You'll also find that the zip files aren't any smaller than the FLACs... not sure why you're bothering.

I wonder if people would use .zip for their .doc's, their games/software, their .iso's, ..... if it was supposed to modify the data in any way.

The truth is that .zip can be more exact* than .flac, for your wavs. ( the downside is that it's not as efficient)



* RIFF chunks / complementary data

I know that .zip stores more than just the file contents, original file name, creation date, etc. Do any of the lossless compressors store anything like this?

Yes, some do : http://wiki.hydrogenaudio.org/index.php?ti...omparison_Table

(see RIFF Chunks).
