    All depends on the type of files you want to compress. JPG is already compressed, so, not the best file type to use for tests.
    For general compression of a mixed bag of file types, I found LZMA2 or LZMA to be the best. Former for machines with high memory, latter in low-memory situations (larger dictionary size possible as with LZMA2, in this case).

    I recommend a FREE file syncronization program called SyncBackFree. I have been using this freeware version of SyncBack for over 6 months now and am amazed how useful, efficient and powerful it is.
    One-click and all my files are backed up and synchronized. I never have to worry about backing up my files again.

    The 2brightsparks website describes this freeware:
    "SyncBackFree has been around since 2003. This world class free backup and sync software has undergone major upgrades since it started life as "SyncBack" freeware and now sports a superb array of options and features, including: Backup. Synchronize: Copy files in both directions. Restore backup files easily.

    Windows 10, Windows 8, Windows 7 and Windows Vista. Both 32-bit and 64-bit versions of Windows are supported."

    If you need additional features - a professional version is also available.

    An internet search a while back found this, and I have been using this to back up my Cygwin64 directory which is 4.42 gigabytes, resulting in a 7zip file of around 855 megabytes. It does take 15 or 16 minutes to run on my Intel I5-7600K with 32 gigabytes of memory:



    7z a -r -t7z -m0=lzma -mx=9 -mfb=64 -md=32m -ms=on archive.7z dir1
    Which are:

    -t7z 7z archive
    -m0=lzma lzma method
    -mx=9 level of compression = 9 (Ultra)
    -mfb=64 number of fast bytes for LZMA = 64
    -md=32m dictionary size = 32 megabytes
    -ms=on solid archive = on

    I just tried this again with LZMA2 instead of LZMA. The time dropped from 15:26 to 9:38, and the size went up from 855 megs to 876 megs. So a definite tradeoff, time versus compression.

    The following RAR command took 10:21, and created an archive of 894 megs:

    rar a -m5 -md512 -r -s cygwin64.2021.10.08.rar c:\cygwin64\*.*

    At least, keep the dictionary size consistent over tests. Larger dictionary sizes compress better. Thing is, LZMA2 uses much more resources, so, using LZMA with larger dictionary might compress better, with much more time investment.

    There are many methods available, simply use what works best for you.

    Using the same methods and parameters, both are identical

    hello friend what a pity ... and one more note before downloading this driver you should have looked first at the release notes and the supported cards ok

    I know but took the chance and try it out no big deal, thought there might was an updated driver for that card but no so I have to stay on the old AMD Radeon Software Crimson Edition 16.2.1 Beta and guess its also the latest given update for that card.
