If you are using Mac OS X system, you might have an issue while unzipping the exported zipped file that you received after initiating a backup/export of all your DeskAway projects. We have seen this happen a couple of times with the inbuilt Mac Archive Utility. To overcome this issue here are 2 solutions:

1. See if the zipped file is corrupt by running this command in your Terminal window:

unzip -t filename

2. If all is well, then use this command to unzip the file. This should most likely work:

unzip filename

3. We have had success with using this application instead of the default archiving tool:

Hope this works!
