Last time we talked about converting files between different formats on your computer with the excellent Zamzar, but what about opening archives directly on board your device? There is nothing more frustrating, in my opinion, than not being able to open certain archives on your device. For the most common archive format – ZIP – I recommend the versatile Resco Explorer, which handles these with ease. But what if you need to open one of the less common archive formats, like RAR for example? Well until now you were out of luck; your only option was to use the MobileRAR Java Midlet that could run inside the IBM JVM which Palm no longer offers for download, and even then it was horribly unreliable. Any file over 5KB it would either spit out and not unpack at all, or it would corrupt it – not something I would want to rely on.

But once again we turn to an online source to help us out. Just the other day I came across a website called WobZip and it claims to allow you to decompress a whole host files online, including 7z, ZIP, GZIP, TAR, RAR, and CAB, just to name a few. It clearly said that it is still under development and may not be the most reliable, but it performed flawlessly in my tests. But the best part is that it can be used directly from within Blazer (you need either PalmOne Files installed or maybe TreoOfflineViewer), NetFront and most other Palm Browsers (obviously, if you were on a PC, you could just use something like 7ZIP…). I may not trust it with really important stuff, but for normal things, it has worked great.

What do you think?

  1. I believe the new limit is below 100mb to unzip.

  2. Great!!!…but how do I actually move and put the file to decompress using treo blazer..i also installed “TreoOffline Viewer” can you help.please

  3. I just tested TreoOfflineViewer, and it doesn’t work. Use this format to enter into the text box

    /NameOfExpansionCard/Directory1/Director2/NameOfTheFile.FileExtension

    Where “NameOfExpansionCard” is the name of your Expansion Card.

    Directory1, Directory2, ect.. is the directory structure the file is stored.

    “NameOfTheFile” is the name of the file you want to upload and “FileExtension” is the File Extension of the file.

    People with PalmOne Files installed (LD/T5), will just see a “Browse” button where they can visually browse to the file.

  4. OMG I never thought of that!!!!

    I have been using palm and wobzip for years (or a year…on wobzip), and that is just SMART!

  5. Thanks for the compliment, and for talking back!

  6. I tried so many times and in different ways and still “no luck”. Well i guess I’m just not- that-smart afterall.
    Didn’t mentioned earlier, I have a T650 at&t, resco explorer and recently webpro v3.01a.

    Maybe these would help.

    and thanks for getting in touch.

  7. Hello nelyyarah,

    Does the 650 have Blazer? If so, go to Wobzip and enter in the text box as explained a couple posts up by me. So if I had a file called “File.zip” off the root of my SD Card named “Card”, I would enter /Card/File.zip

    Then click uncompress. Even if you have entered the correct syntax in the text box, maybe those versions of Blazer and WebPro (older) are not capable of uploading files? Also, try with a small file, large ones cause both NetFront and Blazer to error.

    I have tested, and Wobzip is confirmed to work on:

    Blazer 4.3
    NetFront 3.1
    Webpro 3.5

  8. WOW that was pretty quick. sorry didn’t post sooner. Well here it goes:
    I was so happy..that I went searching for those 3 browsers, thinkin “at last” gloriously something has to come up. then..the unimaginable happens.

    The only thing I’ve got is Netfront3 just about Today, which is great!! But everytime I launch this it resets. Do I need some app so it can run?
    I’ve downloade two alternatives
    1. Has Maxx, which later delete it using Resco Explorer (best app ever) it also resets on launch. I preform a warm reset gave up and got rid of it. entirely.
    2. 320×320.prc and still no effect whatsoever.
    I’m I doing something wrong?
    Can you give me a link to try out.
    like upgrading blazer 4 to 4.3 or Webpro 3.5. Because I can’t find it anywhere, there’ll bunch of bla bla.. Thanx

  9. For help on knowing how to run NetFront on a Treo 650, you may want to do a search at the 1src.com Forums, I can’t really help you with that. (I have never owned or used a 650).

  10. A Treo 650 runs Windows Mobile if i’m not mistaken. Go to rarlab.com and go to downloads. There is one for Pocket PC. Pick that one.

  11. Hi Alamayah,
    thank you so much for talking back!

    Unfortunately, the Treo 650 runs Palm OS – which means that the app you mentioned will not work there…

    With best regards
    Tam Hanna
