The only way it&rsquo;d ever touch any files in a user&rsquo;s folder is if you installed something that let you explicity select a folder to install in (there are very few of those, none are available from Apple publically) and you chose a folder inside your user&rsquo;s folder. The receipt would still be installed in \/Library\/Receipts\/ and it would only affect the user that installed it. It also won&rsquo;t fix permissions for any files that were created during the normal (or abnormal) use of OS X. This means it won&rsquo;t touch any cache files, database files, swap files, or settings files not created by the installer.&nbsp;<strong>If a file isn&rsquo;t listed in a receipt, it doesn&rsquo;t exist to the repair permissions process<\/strong>.
