ZIP and UNZIP (windows only) solution

[euklides]

ZIP & UNZIP  (Windows)
Generally, you can use for instance 7-zip to zip or unzip files (via Shell command)
(program C:\Program Files (x86)\7-Zip\7z.exe  or C:\Program Files\7-Zip\7z.exe)

But here we use PowerShell included in Windows.
Same samples of possible situations.
Of course you need to use your own file names and directories.

'---1--- ZIPPING A SINGLE FILE
ZIPTOCREATE$ = "D:\TEMP\TESTMAKING.ZIP"
MYFILE$ = "D:\CZUR\SV0010_Janvier_1914.pdf"
UU$ = "powershell Compress-Archive -force -path " + Chr$(34) MYFILE$+ Chr$(34) + " " + Chr$(34) + ZIPTOCREATE$ + Chr$(34)
Shell UU$
'Note     -force overwrite existing ZIP.  You can use -update to refresh the ZIP
End

'---2--- ZIPPING MULTIPLE FILES
ZIPTOCREATE$ = "D:\TEMP\TESTMAKING.ZIP"
FILE1$ = "D:\CZUR\SV0010_Janvier_1914.pdf"
FILE2$ = "D:\CZUR\SV0011_Février_1914.pdf"
UU$ = "powershell Compress-Archive -force -path " + Chr$(34) + FILE1$ + Chr$(34) + " ,  " + Chr$(34) + FILE2$ + Chr$(34) + " " + Chr$(34) + ZIPTOCREATE$ + Chr$(34)
Shell UU$
End

---3--- ZIPPING MULTIPLE FILES with ' * '
ZIPTOCREATE$ = "D:\TEMP\TESTMAKING.ZIP"
FILEZ$ = "D:\CZUR\*.pdf" : ' We want here to zip all pdf file located in CZUR directory
UU$ = "powershell Compress-Archive -force -path " + Chr$(34) + FILEZ$ + Chr$(34) + " " + Chr$(34) + ZIPTOCREATE$ + Chr$(34)
Shell UU$
End

'---4--- ZIPPING A DIRECTORY WITH THE ROOT 
REPERTOIREACOPIER$ = "D:\CZUR\MYFILES"  '  (don't add \ at the end of the path)
ZIPTOCREATE$ = "D:\TEMP\TESTMAKING.ZIP"
UU$ = "powershell Compress-Archive -force " + Chr$(34) + REPERTOIREACOPIER$ + Chr$(34) + " " + Chr$(34) + ZIPTOCREATE$ + Chr$(34)
Shell UU$
end

'---5--- ZIPPING A DIRECTORY WITHOUT THE ROOT 
REPERTOIREACOPIER$ = "D:\CZUR\MYFILES\*"    '  ( add \*  at the end of the path)
ZIPTOCREATE$ = "D:\TEMP\TESTMAKING.ZIP"
UU$ = "powershell Compress-Archive -force " + Chr$(34) + REPERTOIREACOPIER$ + Chr$(34) + " " + Chr$(34) + ZIPTOCREATE$ + Chr$(34)
Shell UU$
'Note: the zip file created has not information about "myfiles" directory
end

'---6---UNZIPPING 

DESTINATIONDIRECTORY$ = "D:\CZUR\tempo"   
ZIPTOUNZIP$ = "D:\CZUR\livre.ZIP"
UU$ = "powershell Expand-Archive -force " + Chr$(34) + ZIPTOUNZIP$ + Chr$(34) + " " + Chr$(34) + DESTINATIONDIRECTORY$ + Chr$(34)
Shell UU$
' if TEMPO directory do not exist, it will be created (due to -force option)
End
