Apparently a ZIP file can do this which begs the question why aren't bundle files at least as good as a ZIP?

 
I've had about as many corruption problems with zip files as bundle files, i.e., once in a very very blue moon. The file format is not the problem, it's the vulnerability of the storage medium...which can affect any file format. It's just more noticeable when you can't load an entire file with lots of stuff in it.

 it adds an extra step or two to the process, and is truly no safer than saving as a bundle file.
 
The only extra step is creating a new folder and naming it. 
Also, I have never used a bundle file because I have read way to many threads here where someone has had issues using them. I now see what this is caused by. 
And there are things that can changed by using them, Therefore, a CWP file in a containing folder with the audio is 99.9% safe unless a hard drive goes south, therefore the back ups we all do each 10 minutes or 10 days.. I have never lost important data because I'm always aware of how I'm storing it. I wish Sonar files were not so large as I would be using Dropbox like I use for all my office files now for backup and computer transfer. My internet is to slow. 
My main point was we have always had the "per Project" option it was just a little more manual than it is with the new option. In other words , Cakewalk just automated the process so this is good.
I see the value in using BUN files to strip away unwanted data so they do have a use.

Decent point. The quote was a reference to audiosnap* Cheers.

With Windows 7 or 8 and using an NTFS format for the HDs there is less trouble with files anyway. Bundle files are a safe way to save as just about any other. Its always good to be redundant when you want to be very safe. Save more rather than less. Save 2 bundle files on 2 different HDs for being very safe. Make backups and so on. Use per project files too.
 
 

Seems to me the problem is in SONAR (X2 studio in my case). I recorded some stuff that I saved as bundles on my laptop (Vista 32 bit) then copied the file folder to my desktop when I got home via a memory stick.
 
It opened the files properly once. Then failed - and now none of my bundle files open. Some of my .cwp file don't open properly(on both machines).
 
Went back to the laptop. They failed.
Tried to recopy back from the memory stick - they still failed. Same with the desktop (Win 7 pro 64 bit)
 
In all cases, SONAR x2 opens the bundle file, but the audio clips all show as busy and will not play. The audio folder shows no .wav files in them - including on the memory stick.
 
I have a copy of Music Creator on my laptop and it doesn't even recognize the files as being a Cakewalk file. It does properly open the .cwp and .CWB files it created even though SONAR X2 will not (Same "busy" problem).

There is nothing inherently unreliable about the bundle file; when the subject of potential bundle file reliability has come up before, I've asked if anyone has ever saved a bundle file, then re-loaded the bundle file, and not have it work. So far, that hasn't happened. Even in your case, if it opened once, then it was saved properly. Maybe check that the folder locations for audio samples are correct? (The "busy" problem can also happen if a computer can't find the audio interface.)
 
However - I see no value to bundle files since per-project folders became available as a way to save projects. A bundle file is like a zip file in the sense that if one bit gets dropped or there's an issue with the storage medium, the file will likely be unreadable. If you save a project folder, then even if you lose a few cells on a memory stick or your hard drive sheds some particles and one of the files becomes corrupted, you can still recover the other ones. 
 
I hope you didn't lose the project but if you use that particular memory stick again, I'd recommend re-formatting it. Although it seems solid-state memory sticks should be reliable, I've collected a zillion of them over the years due to receiving them as press packages at trade shows. Although the majority work fine, several have failed, so I use them for temporary backup only and never as a sole backup...mostly just for file transfers, which seems to be your main use as well. But I'd recommend transferring a per-project folder instead of a bundle file.

Bundling and unbundling elsewhere is a good way to clear out some crap from your projects. May even repair some of them...

OK I'm probably looping.. I'll bundle up and try to repair myself....

Should I bounce any tracks that have ussd audiosnap before bundling the file?

I agree with the Doktor. I use them all the time when I finish a project to transfer data from my studio to my live rig. I have never had one not work in any version of Sonar, and it is a great way to clean out all of the excess baggage accumulated during production as only audio used in tracks is copied. Quite often when you delete audio from a track it remains in the audio folder, and I have always found the clean audio folder function to be a bit dodgy.
 
Great point re long term storage that any lost data in a bundle causes the entire project to fail Craig - hadn't thought of that, but don't use bundles for that purpose anyway. I would hate to see the write bundle function disappear though!
