Jar files downloaded from SkyDrive are being renamed to jar.zip files


I have cut and pasted the following series of exchanges from when I posted the problem onto SkyDrive's support forum. I hope that someone might be able to propose a better solution to the problem that I have. Thanks for your help.

Uploaded jar files convert to jar.zip files when downloaded from SkyDrive

I have uploaded an executable jar file to SkyDrive. (I will call this FILE.jar). The file is intact and indicates that it is a jar file type when the file is viewed by Properties within Skydrive. However, when I download (or others download through a share link) the file, it is being saved onto the local computer's download file with .zip appended to the file name (FILE.jar.zip). The downloaded file can be renamed to remove the .zip appendage and subsequently run successfully. However the folder options for the folder where the downloaded file resides must be changed for disable "Hide known file extensions" prior to being able to remove the .zip appendage. While I have figured out the workaround for this problem, this manual renaming procedure is entirely too cumbersome as a solution for sharing this file with others. How can I prevent or disable the FILE.jar file from being renamed to FILE.jar.zip when it is downloaded from SkyDrive?

The file was uploaded by first logging onto my SkyDrive account using Windows 7 Pro and Firefox browser, then a new folder in my account was created without sharing privileges, then the folder was opened and the FILE.jar was uploaded into the folder using the "Upload" option on skydrive account menu. Sharing privileges for FILE.jar were then created (view only), and the shortened url link was sent to the individuals that I was trying to share the file with. was then turned on. When these people use the link to download the file, it is being saved as FILE.jar.zip.

When I try to download the file through the skydrive account download option, it is being saved onto my computer as FILE.jar.zip and this occurs when I try to download the file while signed into my skydrive account as well as when I am not signed into my skydrive account (using the shared file link).

This PNG shows the information provided by clicking on the download icon (down arrow) within the Firefox browser; note that the file was downloaded as FILE.jar.zip and that the source was live.com. When I use Windows Explorer to look at the same file within the Download folder itself, examining the file's properties details also shows that it is being saved as FILE.jar.zip and is of the file type compressed zip folder.

This PNG shows the information displayed to me from my skydrive account when I view the originally uploaded file's properties; note that the information shows that the file is a jar file type.

When I utilize Internet Explorer 9 to access the file, FILE.jar is being downloaded onto my computer as a jar file type. This PNG shows the information provided by Tools/View Downloads within the IE9 browser. Note that in this instance, the information indicates that the file is being downloaded from yzudea.blu.livefilestore.com.

It appears to me that the problem (the FILE.jar file being renamed to FILE.jar.zip) arises from the fact that a jar file downloaded from skydrive using firefox, is being sent from live.com whereas a jar file downloaded from skydrive using IE9 is being sent from yzudea.blu.livefilestore.com.

I want to make sure that a person receiving a share link from me for FILE.jar is able to download it without modification to the file name regardless of which browser is being using to access the link. How can I make sure that this occurs?

Any help is appreciated. Thanks.

Hi MDSms,

I appreciate you for providing as much information as you can about the issue, as well as for uploading screenshots on what you see from the downloaded file. About your initial concern wherein the file gets renamed with .zip after the original file extension, this is solely dependent on the browser that you are using since they have a different safety/security measure that needs to be implemented.

Moreover, you may see the file servers live.com and yzudea.blu.livefilestore.com to be different with one another, but they actually are sent from the same SkyDrive server. This in turn, depends on the web browser where the file is being downloaded as well. The live.com file where it was downloaded from Firefox simply masks its original server yzudea.blu.livefilestore.com.

As for your last query about your recipients downloading the file without the hassle of renaming it from a .zip file, you can simply tell them to download it through Internet Explorer.

Should you have other queries or additional information that might help in our investigation, I highly encourage you to post them here.

Thanks for your reply. Yes, I could simply tell them to download the file through Internet Explorer, but is there another solution or workaround to the problem I have described here? Am I being punished with the curse of this problem simply because I (or the individuals with which I wish to share FILE.jar with) choose to use Firefox instead of IE? Will the use of any other browser instead of IE (Chrome, Safari, etc., etc.) still result in the same problem?

You stated that it is "solely dependent on the browser that you are using since they have a different safety/security measure that needs to be implemented"........could the problem be overcome by designating one or both of the file server addresses as Trusted Sites within the browser options setting?

I look forward to your response. Thanks in advance.

Hi MDSms,

We understand your concern. Since the issue does not occur in Internet Explorer, it has something to do with Firefox's security feature. You might want to verify this concern by contacting Firefox support.

Hope this helps. Let us know if we can further assist you with SkyDrive.

Thanks, Melanie Joy

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.

Further information can be found in the Reset Firefox – easily fix most problems article.

Thank you.

Try to delete the mimeTypes.rdf file in the Firefox profile folder to reset all file actions.
