[The_hesham]

Dear all
i keep reading most of the topics about upx files and download the latest ver from http://upx.sourceforge.net/

I did not found any clear steps of
How to UPX .exe & .dll files?

Can some help, please?

[Whiterat]

Best is:
upx --best --crp-ms=999999 --nrv2b -o FILE_OUT.exe FILE_IN.exe

Best is:
upx --best --crp-ms=999999 --nrv2b -o FILE_OUT.exe FILE_IN.exe

How does that differ from upx --brute file ?


Also upx 3.01 was released on July 31, 2007 so make sure you have the latest version for best results.

Can someone elaborate,

Regards

Ok sparky..how much more elaboration do you need then for two different people to give you sample command lines?

If you can't figure out "upx --brute *" after reading my post you really don't need to run the app. It's a command line app.

I guess "upx --help" was to much effort for you. If this and the previous posts are not clear enough for you I look forward to seeing someone else explain it so you can understand.
