Very slow openig large .WIM files

  • I have Windows 8.1 x64 and 16 GB ram memory.

    When I am trying to open the large .WIM files with size more then 1 GB for browsing it takes extremely long time.

    install.wim file from Windows DVD disk ~2GB.
    I copied wim file to hard drive and tried to open from there, but it didn’t change the situation.

    7-zip needs about one second to open archive, read the folder structure and lets you browse through folders and files, but with PA it takes 230 seconds to open the same archive.

    Tested on versions:

    14.05.01 - 14.05.04

    P.S. Extraction from large WIM and ISO archives also takes long time.
