Speedcams showing wrong speed in Primo2

I do quite a lot of editing of zip's and rar's (I'm an IT manager by profession) and use a product called JZIP which can open many types of files including rar's

I will try wit with winrar though. Don't know why it should corrupt. The file opens up ok and shows the same structure and size.

Some zip files within Primo are not simple zips that you can extract, change, and recompress. They contain a delicate balance of compression techniques and checks which, if not preserved when editing, will render the entire file unreadable by Primo. Many 'normal' zip utilities cannot preserve this file integrity. Winrar can. But only if you work with the file within the Winrar interface, and do not totally extract it somewhere. If you extract the file, change something (or even not change anything), and then re-zip it, the file integrity is lost.

hi
not used my primo 2 for awhlile; but i can also confirm that after YTfix to the data,zip the speedcams now show the correct speed.

I never got this editing lark to work properly. Tried a couple of PC's, the proper winrar program, notepad (and others) and still it won't play ball.

Only thing I can think is that both machines are 64 bit Windows 7 and I am using the 64 bit Winrar product. Shouldn't be an issue I know.

No, that's not the issue. I run in a 'pure' 64 bit Win7 environment with as many 64 bit programs as possible...including WinRar.
There is something you must be doing wrong in the process. Either in how you are opening the archive, clicking on the file within the archive to edit it with Notepad, or updating/saving the changes. There are really only those 3 steps, pretty much. A whole lot of people have done it...but a whole lot of people also have trouble somehow.

yes a 'daft' one but I worked in the field of computing for over 25 years now so nothing suprises me!!!

Like you say there are only those three stages. i've even tried editing at different locations i.e. SDCARD or PC local hard disk but no joy.

Are there a few versions of data.zip doing the rounds. mines a hefty 50k in size but I do remember downloading a much smaller one in the past.

At the end of the day Primo 2 works about 99% and I really like it so this isnt a show stopper. Saying that for some reason my TTS speed alerts seemed to have stopped but that's another head scratching excercise I think.

I'm sure you'll figure out what step is causing the problem eventually.
In any case, one thing is for sure...it's almost never a good idea to edit anything directly off of an SD Card (or to try to overwrite any files on same). Much better and safer to move/copy a file or file set to a mechanical hard drive first, do your manipulations of the file(s), then either delete or rename the file on the SD Card if it exists, then copy your edited file from the PC to the SD Card. Many SD Cards can become corrupted (the file system on them) if many files are constantly overwritten.
There can be some differences in sizes with Primo (any version) or iGo data.zip files. It depends mostly what resolution support is contained within them. The more resolutions (480x272, 400x800, 320x240.....) the larger the zip file will be because each resolution has the same files duplicated, but at a different size structure. Mostly a bunch of graphic files used for display. A data.zip with all possible device resolutions can be 45-50 MB or more, while mine, for example, is 15.7 MB simply because I stripped out all resolutions except the one I need. This affects operation in no way whatsoever..it just saves space on the device to which it is installed.
