Android app creating 1000's of tmp files

Anonymous

Hello,

I installed the latest version of the outlok.com app from the play store. Shortly after, there was over 7000 tmp files in the /root directory. The file names were rotation-xxxx.tmp, and all are 0 bytes. The amount of files is causing performance issues on the device. The device is not rooted.

What are these files and is there anything that can be done to prevent the files from being created?

Thanks in advance,

Joe

    I also had this problem on my Nook HD, 150,000 .tmp files. It took days to remove them. Then a couple of months later, there were over 50,000 .tmp files. This last time I read what you have all said; it seems to have taken care of the problem.

    1. Hold down finger on Outlook
    2. Select uninstall.

    Helpful hint regarding deleting the files.

    1. Uninstall Outlook
    2. Select the root directory where the files are.
    3. Wait until all the files are shown, 150k, 50k, or…
    4. Once the explorer counter stops, select them all
    5. Right-click on the selected files.
    6. Walk away, checking until the “Want to delete files” message box appears. It can take an hour or so to return with the dialog box.
    7. Select delete.
    8. It will ask for verification, answer OK.
    9. Once the deletion windows starts, select a different directory.
    10. If Outlook is still running for some reason, it will continue to add .tmp files. This will cause Explorer to continue showing the .tmp files as they appear. By moving to another directory, the Explorer search will stop, so all resources can be devoted to deleting those .tmp files.
    11. Hopefully you can do this in one clean delete, but you may need to do it a couple of times until all the files are deleted.
    12. It took over 11 hours to delete 47K .tmp files.

    Notes: Outlook seems to have created the .tmp file. Answers above try to get you to think it is something else. When I deleted the 150k .tmp files (with Outlook still installed), .tmp files continue to be created. Once I uninstalled Outlook, no more .tmp files were created.

    DOS Attack. You hear about DOS Attacks on the news as a virus. DOS is a Denial of Service. Hackers try to use up all your computer’s resources bringing it to a crawl. This is a Virus!

    Well, Outlook, seems to be creating these thousands of .tmp file, which… wait for it, is a DOS attack. Being a Microsoft aviate, I believe it is un-tensional but it still it brings my Nook down to a crawl making it is unusable.

    This would take a bit of testing for them, so I could see it not being raided as a bug. Hopefully someone will repro this and get a fix.

    I’m unable to use Outlook on Nook because of this, and it would be nice to get it running without the .tmp file DOS.

    One last note, the .tmp files are zero bytes, so it would not look like something is filling up the disk. That isn’t the issue, when you get thousands of .tmp files, every time the directory is accessed, it must read through thousands of .tmp files to get the directory list. This is the DOS attack, just reading those .tmp files from a computer takes hours.

    Hope it helps people out there, and hope Outlook can repro this and get a fix. My guess it has something to do with syncing the email folders, which would constantly be running, creating those .tmp files, but this and everything else I have written is my opinion based on my experiences.

    Have a happy day!

    Hi,

    Tmp files are temporary files that are saved by browsing the internet or downloading applications. Your device will become slow due to an increase of temporary files that can affect the capability of your device to run any applications.

    You need to clean all the tmp files saved on your device. You can delete these files manually or download a temporary file cleaner on your device to resolve your concern.

    Let us know if it answered your query.

    Regards.

    I had the same experience. A month after installing Outlook on my Android tablet, I noticed it was very hard to browse for files -- File Manager took over 5 minutes to open. I discovered the root directory contained over 16,200 rotation-xxxx.tmp files.

    I uninstalled Outlook and, with some difficulty, deleted all the tmp files. Everything is running normally again.

    It's true that tmp files are created whenever you browse the internet or if you have downloaded an application. Like what you're experiencing right now, the issue started after you downloaded outlook app. Try checking this post:

    If it won't work for you, you can delete those files manually or install a tmp file remover to your device.

    Thank you for the reply, but these are not internet temp files. The files are only created when the outlook.com app is installed. Anyone else have any ideas?

    thanks in advance!
