(Unicode C++) Unzip Selected Files from a Zip ArchiveDemonstrates how to iterate over the files contained within a .zip and unzip specific files. Note: This example requires Chilkat v11.0.0 or greater.
#include <CkZipW.h> #include <CkZipEntryW.h> void ChilkatSample(void) { bool success = false; // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. CkZipW zip; success = zip.OpenZip(L"my_files.zip"); if (success == false) { wprintf(L"%s\n",zip.lastErrorText()); return; } const wchar_t *unzipDir = L"/temp/unzipDir"; // Get the number of files and directories in the .zip int n = zip.get_NumEntries(); CkZipEntryW entry; int i = 0; while (i < n) { zip.EntryAt(i,entry); if (entry.get_IsDirectory() == false) { // (the filename may include a path) wprintf(L"%s\n",entry.fileName()); // Your application may choose to unzip this entry // based on the filename. // If the entry should be unzipped, then call Extract(unzipDir) success = entry.Extract(unzipDir); if (success == false) { wprintf(L"%s\n",entry.lastErrorText()); return; } } i = i + 1; } } |
