http://nagoya.apache.org/bugzilla/show_bug.cgi?id=23602 Zip task STILL creates zip files incompatible with Winzip ------- Additional Comments From [EMAIL PROTECTED] 2003-10-29 00:46 ------- To try to get more info about this problem, i contacted the Winzip support group, and gave them access to the same sample files provided in my last post. Their response seems to shine a little light on the issue: Using a Hex editor, it appears to me these two Zip files contain the same exact data set. I do notice one difference between the two Zip files. The reported value in the "Size of the Central Directory" field within the "End of Central Directory (PK0506)" differs between the two Zip files. The Zip file called ANT141_ziptest.zip contains a value of "6090 0F00", where as, the Zip file created with Apache Ant contains a value of "9FBC B1FF". I ran a quick test where I modified the value in the "Size of the Central Directory" field for the Apache Ant created Zip file to mirror the value found in ANT141_ziptest.zip. After the modification, I was able to open the modified Apache Ant created Zip file with WinZip without encountering any error messages. For some reason, the Apache Ant program is placing an incorrect value in the "Size of the Central Directory" field within the "End of Central Directory (PK0506)". Unlike other Zip utilities, WinZip begins reading a Zip file from the last record (End of Central Directory) to the first record (Local File header). Where as, other Zip utilities operate in a reverse fashion (first to last). This might explain why you were able to open the Apache Ant created Zip file with some other Zip utilities, but not with WinZip. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
