 peterm: While 7-zip is a useful program, and I make quite a
lot of use of it, including the command line version
"zip.exe", I also use the older EnZip (which is not
trully portable, I accept). It displays filesizes
to 2 decimal places and allows the compression settings
to be varied when using drag and drop. It is also a
little more convenient to use when dragging and dropping. [2007-03-15 06:52]

 mr M: I found 7zip to be very useful in most cases.
It's weakness is in handling password protected RARs
Unfortunately 7zip does not allow RAR archive's contents or comments to be viewed without the password even when allowed to do so in WinRar.
This is frustrating when the comments within the RAR shows the password.
I was hoping if anyone knows of any portable app that can view the comments without a password? [2007-05-23 23:45]

 aldor.cyv: Don't forget, either, that 7z is an open format (read by many free and non-free software), 7-Zip itself is free software and (here's the bit that I love) 7-Zip can double as a dual-pane file manager (under the View menu, select "2 Panels").

It also works under Wine [2007-05-29 04:54]

 Comoman: (@ mr M) Just out of curiosity, what is the purpose of a password protected RAR with the password in an unprotected comment? Isn't that a bit like locking your house and then taping the key to the door? [2009-01-16 10:02]

 Midas: @Comoman

Diversity unfanthomable... If you build it, they will come! [2009-01-19 06:20]

 Terry: It's not really a self-extracting ZIP file any more, it's an installer, though it just copies to whatever directory you tell it without modifying registry or the rest of the filesystem [2009-01-21 11:45]

 Jon Wright: @Comoman: "What is the purpose of a password protected RAR with the password in an unprotected comment?" - It's for when you want humans to be able to extract it, but not machines. [2009-03-16 03:37]

 Hugh H.: If you want to find out what's in a gargantuan .RAR file set, you download the first file and un-RAR it. When you try that with 7zip, it takes a giant dump when it can't find the rest of the files -- I had to use Task Manager to kill it. (the "cancel" option was obviously modeled after Microsoft code -- it ignores the user completely)

It's also slower than continental drift!

Meh! [2009-03-26 10:19]

 Lynird: Just what im looking for. I can see the folders & .doc files in rar archives just like clasic windows browser
Thanks !! [2009-06-14 09:03]

 ugo: bravo!!! [2010-06-28 02:17]

For more general topics (eg. whether apps that write to the registry, leave traces on the host machine, rely on certain versions of IE etc. can be considered portable), please post to the Portable Freeware Discussion forum. If your virus scanner has detected a virus in the application, please email the author directly or post to the forum. Note that false positives (i.e. flagging a virus when there is actually none) are extremely common for virus scanners. When in doubt, try an online scanner like Online Malware Scanner or VirusTotal, which scans files using multiple anti-virus engines. It is very likely to be a false positive if only a few engines raise the red flag.
