Could someone help me to check if there is an application for android where I can rename the extension of a file? for example file.avi to file.wmv. I would like to change the extension of a file using the DHD device. Anyone who can give the name of application sure would help a lot of us here. Thanks. DHD is the coolest phone for far!
If you go into the market and download File Expert you will find that you can rename the whole file name to whatever you want, that's including the extension.
would it be possible now with mango for someone to make a app called Zip Manager or something that lets u d/l Zip and/or Rar files to that app and the zip files are only accessible within that app to open documents and other files contained in them and manage them in that app?
same with mp3 or other files be able to manage them in that app only?
the Free Music app made me think of that... we cant d/l mp3s through the browser and add to the device library but we can manage the mp3s we download through that app and with the paid version we can sync the files over
could something similiar to this be made to manage zip and rar files????
Due to the sandbox nature of WP7, you can't access the local file system. Also I don't think 1 app can open another app. So for example, you couldn't unzip a PDF and then call Adobe Reader to view it.
One way around this would be for your zip / rar app to download the file, un-compress and then upload it to a folder on skydrive. Then it would be there ready to open and use. I'm pretty sure I read that WP7 can already open zip files, so maybe you can already do this through the browser? What are you trying to download exactly??
an other good idea is too contact htc samsung lg or dell to make a app for bluetooth in and outbox and zip app all in one

not really trying to do anything in particular I just kno on my tp2 I use to dl music in rar files all the time and documents thru zip folders.
Hello,
I have an idea to make an App, and I have one problem, I have to upload one folder that its content have a lot of files and folders in order to upload to skydrive. I think that it is more easy if I compress the main folder and then upload this compressed file. How Can I compress this folder?
Thanks you

Hi dazza9075,
Thanks by your answer, but I thought the same, but I don't know how to use this, Can you explain about use of zip? Or, Where can I find information about this?
Thank you again

+1 for the idea... I also want a program like winrar which also available in symbian phones.plz any dev note this and develop an app for compressing and decompressing files...
WP will unzip zip files, make the sip, copy to sky drive, open via IE, it will then give you the contents of the zip,, it can't compress files to zip though. Technically there would be little point since docs auto sync to sky drive, and WP doesnt support anything else or file system access, but its doable for unlocked devices I suppose

Hi dazza9075,
Thank you by answer, I had thought that it isn't possible, because I want to compress a folder of other app that her content are a lot of files and folders. So, Do some api exist in order to compress this? Or, Have I upload files and folders one by one?
Thank you again
I think it's completely possible
sombody names Ego zheng,wrote an application. It is program manager.
u can repack your apps,and save apps data in a single .zip file.
i think he can do this
contact him for this idea.

its doable so long as you have interop unlock and WP tools installed and setup
if the Windows Phone SDK is missing Zip functionality (it may be called "DEFLATE" which is the name of the compression algorithm; ZIP is the file format) then there are surely libraries for various compression methods which you could download. Alternatively, if you don't mind using native code homebrew, there are compression libraries (zlib, etc.) that can be compiled to a native DLL, and you could then access them via COM.
i add this to new version of my file manager and now you can compress and decompress file and folders
Hi!
Thanks you by your answer, they have been very useful.
Thanks you
Hi again,
I'm using the lib "SharpZipLib" and I have problems with it. Can you explain how use it? or what is the problema? I probe in a program of pc and it working correctly but in app for my mobile say it crashed when it go to create the file, this is code:
FileStream fsOut = File.Create("Copia.zip"); //here is the problema at this moment
ZipOutputStream zipStream = new ZipOutputStream(fsOut);
zipStream.SetLevel(3);
zipStream.Password = null;
........
It can't create the file.
Thank you again
Generally speaking, Silverlight (which WP7 uses for apps) doesn't even allow normal file access, so you might just be getting a MethodAccessException on File.Create. If not, that still won't work without elevated privileges. The default working directory for a program is it's install directory. For a WP7 app, that's going to be either its install location (\Applications\Install\<GUID>\Install) or the Windows directory where the taskhost.exe file lives (\Windows\). Trying to create a file without specifying full path will crete it relative to the working directory, which in this case means creating it in the working directory directly (no path specified). Since the app can't write to the working directory, you'll get an error from that too.
To get around the permissions error, use the IsolatedStore folder (\Applications\Data\<GUID>\Data\IsolatedStore\) or run the app with full permissions ("Trusted" or root unlocked).
Does anybody know of an app that would allow me to edit .zip files on my phone? Sometimes before flashing a ROM I like to remove some system apps, which I use winrar for on my PC. But I use es file explorer on my phone and it can only view and extract .zip files. thanks to anyone who can help!
Nevermind! I did a quick search on play store after I posted this, not sure why I didn't do that first but ZArchive does exactly what I need.
I am trying to open / save a mpeg 4 video file that I converted from an avi file that I compressed into a zip file. I email the file to myself through gmail. When I click on the file I get a message that says I can't open or save this file. The same file can be opened on my desktop. I have the same issue on my phone which is also an android. I am running kitkat on the Nexus & Jellybean on my phone. Maybe I'm missing something or do I need a specific app to open the file ?

Last I recall avi files dont compress much from a zip.
Plus you would have to deal with the zip file, lets say 300mb, then extract it, to another 300mb or so.
I think you would be better off just sending the avi file as is.
All you need to do is connect your nexus as a media device through the storage settings. (Make sure USB debugging is turned off in developer options). And then drag the uncompressed version over to your nexus from your computer. No need to email it if you have a computer. Make a folder called movies (don't have to just easier). And then download mxplayer from the play store of you haven't already.

Google is forbid us to save potential harmful attachment, including zip files.
So, If you insist using email, you need to open web browser and go to gmail website, login, and download the attached file.
Your file will be downloaded as downloadfile.bin.. You need to rename using file explorer to donwloadfile.zip, and then open & extract that file.
I'm using kitkat, and this method works for me.
