/unzip & $unzip() v1.0

By ^WeSt on Jun 22, 2018

This is an usefull alias/identifier that allowing you to unzip/extract an ZIP file (and only .zip file) into a specific destination/folder without any extra tools by using Windows functions, it was tested under mirc 7.52 on Windows 10 and working, i am not sure if it is working on other windows versions.

Usage:

/unzip [-do] <"ZIP File"> <"Destination Folder">
(It will echo an successfully message if succeed otherwise an error message will occurr)
Note: You can use the /.unzip command thought to unzip/extract the ZIP File to not get any echo messages back!

-d (optional) = Will delete the ZIP File when extracting finishes successfully.
-o (optional) = Will open the Destination Folder when extracting finishes successfully.

$unzip(ZIP File,Destinaton Folder).[destroy open]
(If the unzip/extract succeed then it will return 'SUCCESS' message back, otherwise it will return zero)

.destroy (optional) = Will delete the ZIP File when extracting finishes successfully.
.open (optional) = Will open the Destination Folder when extracting finishes successfully.

Examples:

/unzip "C:\Users\westor\Downloads\test.zip" "C:\Users\westo\Downloads\test_folder\"
/.unzip "C:\Users\westor\Downloads\test.zip" "C:\Users\westo\Downloads\test_folder\"
/unzip -d "C:\Users\westor\Downloads\test.zip" "C:\Users\westo\Downloads\test_folder\"
/unzip -o "C:\Users\westor\Downloads\test.zip" "C:\Users\westo\Downloads\test_folder\"
/unzip -do "C:\Users\westor\Downloads\test.zip" "C:\Users\westo\Downloads\test_folder\"

//echo -a Unzip progress: $unzip(C:\Users\westor\Downloads\test.zip,C:\Users\westo\Downloads\test_folder)
//echo -a Unzip progress: $unzip(C:\Users\westor\Downloads\test.zip,C:\Users\westo\Downloads\test_folder).destroy
//echo -a Unzip progress: $unzip(C:\Users\westor\Downloads\test.zip,C:\Users\westo\Downloads\test_folder).open
//echo -a Unzip progress: $iif($unzip($mircdirdownloads\test.zip,$mircdirdownloads),OK,ERROR)
