Viewing files Sparsebundle

You shouldn't "open" the sparse bundle. When you double-click, it should mount like a hard drive.

You can do nothing with it as you see it.

While it is actually a folder, it should be "packaged" to act like a file. If it looks and acts like a folder, it is broken.

Ctrl-click on it and choose Open With > Other.

Look for DiskImageMounter in /System/Library/CoreServices/ and try to open it with that.

That may not work if Finder thinks it is a folder and not a sparse bundle disk image.

If that doesn't work, you may be able to drag the sparse bundle onto the DiskImageMounter application. If it highlights when you drag it onto the app, let go and it should mount it.

The .inProgress shows 1.35GB data. Its been like that for a long time. What should I do next?

As I tried to explain before, and as Boyd Porter pointed out, you shouldn't use it for anything except maybe getting newer version of a file that doesn't exist in the most recent date-stamped folder.

It is not a full backup and never will be.

Boyd Porter also brings up a good point. Why are you viewing this backup in the Finder and not the Time Machine interface?

Do not worry about it. The in progress file is a backup that was interrupted. Normally it finishes the backup during the next backup. If it is old, just forget it.

It is not a good idea to explore your backups with the Finder anyway. Use the Time Machine interface to manage your backups.

Have a nice day.

A sparse bundle disk image does not release the space freed up when deleting files from the bundle. You can shrink it (which I imagine TM does periodically), but the size of the bundle does not necessarily reflect the data stored within it.

The .InProgress folder is not a complete backup. It is the backup that was in the process of being backed up, so it may not have the full backup in it.

You should be looking for files in the most recent dated folder, or use the alias named, "Latest."
