![]() Do it in the opposite order on a set of files you haven't touched earlier during the current Windows session, and I bet the result will be reversed. Naturally the second time around Windows had already cached the data, so the process took a fraction of the time it did initially. If you saw a huge difference, it could only have been if you tested WinRAR on a set of files first, then immediately compressed the same files with Compressed Folders. ![]() Other than the extra time taken to open WinRAR's Add to archive dialog, select ZIP as the archive format and press OK, the actual time taken for compression was roughly the same for both, with WinRAR taking less time in general (albeit the differences were negligible). "I just found out that zipping with windows' "send to" works as good as Winrar's "best" zipping, but so much faster." - I just tested this, multiple times. It's not that they're putting the Pressure on Windows, but maybe the Pressure.Net? :-) If someone blathers on about how Windows supports Unicode, you can suggest they just ZIP it, if you like! Unicode? Zip don't need no stinking Unicode! You can read the sordid details about this peculiar lack of Unicode support in Windows in the following series of blog posts by Microsoft's Michael Kaplan: I guess they expect everyone to install one of the many full-featured third party archivers available, which is precisely what I recommended to you as well above. 4.5 did not get this right initially, but the bug has since been fixed). Also, as a clear sign of just how much it cares for this feature, Microsoft has not updated the code to fix this bug till date (apparently, even the new System.IO.ZipArchive class in the latest version of the. Unfortunately, Microsoft for some strange reason licensed a third party library for its Compressed Folders feature (although it's not terribly tough to code ZIP support), and obviously this library pre-dates the addition of Unicode to the ZIP file format. Since then of course all of the major Windows archivers implementing the format have been updated to include Unicode support, beginning I believe with WinZip in 2008. Limitation, this specification will support the following change. Names in other character encodings, or languages. ![]() Original MS-DOS range of values and does not properly support file This limits storing file name characters to only those within the As per APPENDIX D - Language Encoding (EFS) of the ZIP File Format Specification:ĭ.1 The ZIP format has historically supported only the original IBM PCĬharacter encoding set, commonly referred to as IBM Code. The ZIP file format lacked Unicde support for a long time, and this extension was only added 6 years ago in 2006. Not all zip features are supported by the Windows Compressed Folders capability.įor example, AES Encryption, split or spanned archives, and UnicodeĮntry encoding are not known to be readable or writable by theĬompressed Folders feature in Windows XP or later versions. Microsoft calls this feature "Compressed Folders". Versions of Microsoft Windows have included support for zipĬompression in Explorer since the Plus! pack was released for Windowsĩ8. However, if the offending characters are something like ™ as mentioned above, I do not believe there's any official Microsoft fix for this zipfldr.dll limitation, that has existed as long as Windows has had this feature (so if you really did fix it earlier, possibly you installed some third party component). If you're prompted to restart your computer, click Restart now to do so. If you are prompted for an administrator password or confirmation, type the password or provide confirmation. Open the Region and Language Control Panel appletĬlick the Administrative tab, and then, under Language for non-Unicode programs, click Change system locale.

If the offending characters are from a language other than English but one Microsoft supports, you can install the relevant MUI (Multilingual User Interface) language pack from Windows Update, or the relevant LIP (Language Interface Pack) from here as a possible fix. ![]()
