Question:

CkZip windows path with whitespace

Nov 27 '16 at 15:01

Hi, I am trying to open a zip file with CkZip on windows. The zip file path has a whitespace in it. Which format is expected by CkZip for whitespaces in windows? Should the whitespaces be escaped?

This fails:

CkZip zipModule;
bool success = zipModule.UnlockComponent(CHILKAT_KEY);
success = zipModule.OpenZip("c:/test/filename with space.zip");

Thanks

EDIT: it appears the actual error is caused by another reason. I think it is related to some SFX flag in the zip files that cause the failure. All files with SFX flag set to true failed to extract.

Here's the last error log:

I tried opening a Zip with spaces in file names without issue (even tried forward slashes like you did and that seems to work even though Windows typically takes backslashes as path separators).

Did you get an error? If so, please post the complete contents of the LastErrorText property immediately after calling the OpenZip method.

SFX isn't a flag - it's a self extracting executable file. It may include ZIPped components, or it may even use a different compression algorithm. Essentially, it's not really a ZIP file, so I don't think you can expect it to be opened/unzipped by the Chilkat library.
