Instead of just displaying the output folder and offering to customize it, you can now select additional options: Open output folder - This loads the folder the files are extracted to after the operation completes. Delete source archive - Removes the source archive on successful extraction from the hard drive. Open Button - Opens the output folder when you clik on the button. In addition to that, it displays the total disk space on the selected drive and the free disk space. 7-Zip uses different history files for archives extracted using the 7-Zip file manager and the extraction dialog. Easy 7-zip uses the same history for both extraction methods and will display up to 30 previous folders when the history feature is invoked. A fourth change modifies how the background button during file compression works. If you hit background in the original 7-Zip, it will set the process priority to low. The modified feature will minimize the dialog to the system tray on top of that to move it out of the way. Last but not least, it is featuring a unified installer that can be run on 32-bit and 64-bit versions of Windows.

While still far behind PAR2 (or even the shady ICE Ecc), it is an important feature in Archiving that deserves more attention. 2 Hide PreferLinux , March 19, 2013 1:47 AM mayankleoboy11. There is no difference between LZMA and LZM2 . Both are the same algorithm. The only difference is LZMA is limited to 2 threads. LZMA2 is much more threaded, but uses double the amount of RAM. 2. PPMd is strictly for compressing text. It compresses text better than any other algo. But it is limited to 1 other core only.
