(Tcl) Unzip Selected Files from a Zip Archive
Demonstrates how to iterate over the files contained within a .zip and unzip specific files. Note: This example requires Chilkat v11.0.0 or greater.
load ./chilkat.dll
set success 0
# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.
set zip [new_CkZip]
set success [CkZip_OpenZip $zip "my_files.zip"]
if {$success == 0} then {
puts [CkZip_lastErrorText $zip]
delete_CkZip $zip
exit
}
set unzipDir "/temp/unzipDir"
# Get the number of files and directories in the .zip
set n [CkZip_get_NumEntries $zip]
set entry [new_CkZipEntry]
set i 0
while {$i < $n} {
CkZip_EntryAt $zip $i $entry
if {[CkZipEntry_get_IsDirectory $entry] == 0} then {
# (the filename may include a path)
puts [CkZipEntry_fileName $entry]
# Your application may choose to unzip this entry
# based on the filename.
# If the entry should be unzipped, then call Extract(unzipDir)
set success [CkZipEntry_Extract $entry $unzipDir]
if {$success == 0} then {
puts [CkZipEntry_lastErrorText $entry]
delete_CkZip $zip
delete_CkZipEntry $entry
exit
}
}
set i [expr $i + 1]
}
delete_CkZip $zip
delete_CkZipEntry $entry
