7ZA UDF, just another 7-zip UDF...

[t0nZ]

Always searching for the "final" solution to my zipping/unzipping needs, I started years ago using WinRar with AutoIT (don't ask me why...) and for the last 10 years I worked well with the _zip.UDF , a good solution using the embedded windows zipfldr.dll.

But often I work with a lot of data (both multi gigabytes and/or 100K+ files) and I noticed the performance of the windows zip DLL are not so good, the problem is maybe worsened by the mono thread operation using AutoIT +  zipfldr.dll.

SO my choice is 7zip (7ZA.exe)  also for licence (freeware also for business) reasons, and I wrote a small and simple UDF:

You have to provide 7za.exe, in scriptdir in some way, maybe with a fileinstall or embedding in some way. 

Daily I use most of the time:

_UNcompress_7za

_COMpress_7za_7z

so I'am almost done with these funcs....

Also I made a quick and dirty benchmark on some real world data (for me at least) , comparing the windows DLL, the zip ULTRA by 7zip and the various 7zip levels.

My choice is level 4 (time/size) but your mileage may vary...

Also, extracting many thousands of little files from a 7z archive with 7zip is waaaay fast in respect to other solutions.
