Always move the file to your desktop computer, then open it, to prevent file damage.
Never have your Quicken file open on two computers at the same time.If you do attempt to share Quicken files across multiple computers using Dropbox, you'll need to follow these rules: If your file is damaged you have no option but restore a backup. Subscription Release users can access Quicken on the Web on any computer to review accounts, without needing to install Quicken on additional computers or move data files. This is because opening the same Quicken file on multiple computers at the same time can result in data damage or even file corruption. Sharing a single Quicken file across multiple computers is not recommended for new or non-technical users, and is not officially supported.
