Temporary storage on your local computer is too low. (ErrorCode: 0x02040012) RRS feed

  • Question

  • I am attempting to migrate around 300GB of files to SharePoint online using the latest full release of the SharePoint Migration Tool.

    I haven't found any machine requirements in the documentation, free space, RAM, CPU minimums etc so am using it on a machine with about 20GB free on C (since no reference was made to this I presumed it wasn't important). I did find a random blog post from someone on the internet claiming 150GB is required to be free, can anyone confirm this?

    Needless to say the application fails to do the initial scan of the data saying "Temporary storage on your local computer is too low. (ErrorCode: 0x02040012)"

    If you hit the "play" button to continue the migration, the scan will keep going until C is full and then fail again.

    I have another drive on this machine, with 1.5TB free, can I somehow point the location that the SharePoint Migration Tool is using as its default temp file location (obviously located on C somewhere) to this other drive?

    If not, does anyone have any suggestions for getting around this problem?

    PS: If free space must match the size of the data, getting hold of a machine with +300GB available on its C drive will not be possible for me so unfortunately that is out of the question.

  • If anyone else has this problem, pretty easy fix. Leaving question here for documentation perposes.

    In %appData%\Microsoft, Migration Tool creates a folder named "MigrationToolStorage" in which it saves the blobs or temporary data whilst it scans & uploads etc etc.

    I just used mklink to point a junction to my external HDD that has plenty of space and we're up and running.

    So delete your MigrationToolStorage folder in Appdata if it already exists.. then, open CMD:

    cd %appdata%\Microsoft
    mklink /J MigrationToolStorage Z:\SomeOtherFolder

    Where "Z:" above is a different / external drive that has more space to do the actual migration.

    I'm assuming your free space has to match the size of the upload to SharePoint.

  • Before you starting the migration, go to advanced settings and change the Sharepoint Migration Working path to a  external hard drive or a another partition that may having a free space. Then start the migration :) 

    This works 100% for me.

  • Thank you , I was able to reallocate the temp location to alternate location.

  • Changing the the working folder worked for me.
