--- Comment #4 from 2wxsy5823...@opayq.com --- I tested using p7zip 7z / 7-Zip 7zz and also Ark with p7zip plugin, and I guess it may be related to upstream issues, e.g. - https://sourceforge.net/p/p7zip/bugs/105/ - https://sourceforge.net/p/sevenzip/bugs/2316/ However, I guess Ark may also have an issue - Ark does not show the "Unsupported Method" error returned by p7zip. Password issue: Maybe upstream issue Empty files issue: Maybe upstream issue Unsupported method issue: Maybe Ark issue ----- ----- ----- Case 1 - ZIP using Deflate and AES256: If using p7zip plugin to extract the file, and a wrong password is entered, Ark shows an error that the password is incorrect, but empty (0B) files are still created. If using Info-Zip plugin to extract the file, Ark shows an error that the encryption method is unsupported. If using p7zip 7z / 7-Zip 7zz to extract the file, and a wrong password is entered, it shows "ERROR: Wrong password" but empty files are still created. Case 2 - ZIP using Zstd and AES256: If using p7zip plugin to extract the file, and ... Wrong password is entered: Ark does not show an error that the password is incorrect or the compression method is unsupported, empty files are still created. Correct password is entered: Ark does not show an error that the compression method is unsupported, empty files are still created. If using Info-Zip plugin to extract the file, Ark shows an error that the encryption method is unsupported. If using p7zip 7z / 7-Zip 7zz to extract the file, and ... Wrong password is entered: p7zip does not show "ERROR: Wrong password", only "ERROR: Unsupported Method", empty files are still created. Correct password is entered: it shows "ERROR: Unsupported Method", empty files are still created. Case 3 - ZIP using Zstd and unencrypted: If using p7zip plugin to extract the file, Ark does not show an error that the compression method is unsupported, empty files are still created. If using Info-Zip plugin to extract the file, Ark shows an error that the compression method is unsupported. If using p7zip 7z / 7-Zip 7zz to extract the file, it shows "ERROR: Unsupported Method". ----- ----- ----- Test environment: - Ark 21.08.3 - p7zip 16.02 (Original p7zip) - 7-Zip 21.06 (developed by Igor Pavlov) (see also Bug 440135) ----- ----- ----- Note: Some distros (e.g. Arch Linux) provide jinfeihan57's fork of p7zip (https://github.com/jinfeihan57/p7zip). That fork supports Zstd in ZIP while the original p7zip does not support Zstd in ZIP. -- You are receiving this mail because: You are watching all bug changes.
