Unsolved Errors Testing Multi-Volume 7-zip Archive
-
I’ve found a bug when trying to test an encrypted, 28-volume 7-zip archive of a 18.3 GB folder containing 41,751 files. The test fails, showing errors in all files.
- Here’s the folder I compressed, and the 28 resulting files:
- Here’s the multi-volume compressed file opened in PA, showing the total file count and the full archive size:
- And here’s the test results screen after I click Actions -> Test…, showing an incorrect file count and archive size (this seems to be the file size of the first volume alone):
One important detail about the test screen above is that PA opens an UAC prompt asking for privileged execution before starting the test. Is this the expected behavior? It seems PA wouldn’t need higher execution privilege since everything it’s touching is owned by my own user.
In any case, granting or denying the UAC prompt results in the exact same screen.
- Now, if instead of testing the archive I tell PA to extract the contents, the operation works fine (and with no UAC prompts):
- With the Properties panel for both folders, the original and the extracted one, showing the exact same file count and total size:
I hope this helps. 🙂
