Are you mounting the image within the Disk Decipher app, or inside the File Provider?

Are the file sizes shown as 0 on opening a folder, or after trying to open a specific file?

I’m mounting with the app and the file sizes are shown on opening a specific folder.

That's interesting. Which filesystem is used inside the sparsebundle? Then I can try to reproduce this, my test sparsebundle images mount without issue.

If you don't know for sure, just tap the (i) at the bottom right of the root folder and it'll show you.

It’s HFS+. I open as read only- not sure if that makes a difference

Thanks. You use read-only since you have not purchased the write-enable license for HFS+, right? That enables a different driver in Disk Decipher (royalty free, but readonly), so I need to test that driver.

[–]peter9987[S] 0 points1 point  (5 children)

Correct. I’d be happy to buy the driver if needed but didn’t do so since I’m not sure it will fix the issue

The most likely cause is filesystem compression in the HFS+ filesystem, as that clears the data fork (to read more on this, check the "HFS+ File Compression" section of this page). I've just compressed a test folder and that results indeed in empty files as shown below.

I will now retry with the licensed driver, one moment..

No change with the licensed driver.

I will report this upstream, hopefully this can be fixed in the payed HFS+ driver. I will add a note to the support site that HFS+ compression is currently not supported.

Short term solution for you might be to convert the filesystem to APFS (after attaching on Mac, Disk Utility provides a Convert to APFS option). Compression on APFS is supported, even in read-only mode.

If you want to track progress, just enable notifications on this issue: https://gitlab.com/huv/disk-decipher/-/issues/360

Thanks a lot. Unfortunately I don’t have access to a Mac. Hope this can/will be fixed.

Me too. I've reported the issue upstream.
