# Problems retrieving data from the iPad

### Problem with backing up data using iTunes and similar tools

#### Problem:

The research data on the iPad is stored in separate folders for each study, test leader, and group/class.

If any of these folder names occur more than once with different capitalization (e.g., “proefleider anne” and “Anne”), the transfer system between the PC and the iPad cannot distinguish them and will refuse to proceed.

Corsi version 5.0 build 50 and higher solves this problem by converting everything from “Anne” to “anne.”

After this, iTunes and similar tools can once again work with the app’s internal file system on the iPad.

### Solution:

<span class="content-subhead">Check if you can find this version in our App Store. (If not, report it via [cjj.stoof@vu.nl](https://mneme.psy.vu.nl/appstore))</span>

#### <span class="content-subhead">2. Install a newer version of Corsi</span>

<span class="content-subhead">Download the most recent version of Corsi from our [app store](https://apps.fgb.vu.nl/apps/corsi/page/download) </span>(overwrite the old version, do not delete it first).

<span class="content-subhead">Start this version, and the file system on the iPad will now be repaired. </span>

<span class="content-subhead">Then close this version, and you can copy your data.</span>

#### <span class="content-subhead">3. Install the desired version of Corsi</span>

Install the desired version of Corsi from our App Store. Do not delete the other version of Corsi on the iPad; simply overwrite it.  
You can now still copy your data.

Start Corsi and check if it’s the correct version.

You can now continue with your research.
