| Explzh 9.70 Apr 7, 2025 |
In v.9.69, we fixed the inability to create zip2.0 encryption format (legacy encryption method with descriptor). We also improved the conversion between zip64 encrypted archives and normal archives (CTRL+Z or CTRL+SHIFT+Z). Fixed a problem where some packages could not be opened in appx, msix, appxbundle, or msixbundle formats. Supports repair of appx, msix, appxbundle, and msixbundle. Automatic updates can now detect versions of Arcext.dll with decimal points. Fixed a bug that caused an archive to have a header error (but could be expanded) when compressing after creating an uncompressed zip64 in v.9.69 and earlier, and made it possible to repair the header error correctly from "Repair Archive". Fixed the progress bar in the progress dialog not moving when compressing cab files. Applied Visual Studio 2022 v.17.13.5. |

Fixed an issue with converting zip files larger than 4GB (zip64 with extended local headers) to encrypted zip files and decrypting them. Fixed a problem with the repair function handling zips with extended local headers (zips created by Explorer, etc.) (Explzh does not use extended local headers). Updated to Visual Studio 2022 v.17.13.3. |
| Explzh 9.65 Feb 17, 2025 |
Fixed a bug in zip64's "Repair zip archive". (We recommend checking for zip corruption using the shortcut key CTRL+I. It does not waste computing resources and time.) Fixed a bug where "Convert and save archive" to tar.zst was converted to tar.xz. "Archive validity check" for multiple zips from the shell extension now uses strict header-only checks. Fixed a bug that caused the program to crash when scrolling horizontally after displaying files that cannot be displayed in a single line in the result log (such as files with long path names). Applied Visual Studio 2022 v.17.12.5. |
| Explzh 9.64 Feb 6, 2025 |
"Repair Zip Archive" now checks the header for validity before execution (without CRC checking), and repairs zip files (including office documents) with damaged headers. (The shortcut key "CTR+I" performs a strict check of the zip header, and displays a repair confirmation dialog only for zip files that are found to be damaged. It is fast because it omits the CRC check.) Executable files that have zip in their resources are now excluded from "Repair Zip Archive". |

| Explzh 8.98 Apr 11, 2023 |
The 32-bit version can now specify compression levels up to 22 when creating zstd. Changed to use zlib+zlibWrapper (zst's zlib wrapper) for deflate compression/decompression. AES-encrypted zips (AES-encrypted zips with invalid headers) of the zip xz method created in v.8.95 or earlier can be deleted from [Decrypt ZIP archive] or [Encrypt ZIP archive] with the correct encryption. It is now possible to restore to a encrypted ZIP archive. Apply zstandard 1.5.5. |
