If you work with PsyToolkit, it is best to use the newest browser you can get for your operating system. PsyToolkit recommends the Firefox or Google Chrome browser.

When you download a zip file for uploading in your PsyToolkit account, make sure you download the zip file as it is. Make sure you do not decompress it. Some web browsers do this automatically, in particular the Mac Safari browser.

Here is what you need to do when you use Mac Safari

  1. Open Safari

  2. Open the Preferences menu:

  3. In Mac OS X: Click Safari > Preferences

  4. In Windows: Click Edit or Settings (Image) > Preferences

  5. In the window that opens, click General

  6. Remove the check from the box beside "Open 'safe' files after downloading"

  7. Download the file again

Here is what you need to do if you use Firefox

Option 1: In Firefox, you can right-click the zip-file link (if you have a right mouse button). It will say, "save link as".

Option 2:

  1. Select the preferences (in the menu)

  2. Select Applications

  3. File "Zip archive" and select "Save File" or "Always ask"

Here is what you need to do if you use Google Chrome

Google Chrome saves zip files as zip file by default. If not, you can right-click the zip-file link (if you have a right mouse button). It will say, "save link as".

Here is what you need to do if you use Internet Explorer

Click the hyperlink and then click "Save this file to disk". You can also rightclick the link.
