dat files

About this tag
Discussions on WindowsForum.com about .dat files cover several practical issues. Users report problems with email attachments arriving as .dat files instead of PDFs or images, particularly in Windows Live Mail and IncrediMail. Others seek help changing the default icon for all .dat files in Windows Explorer, including icon size requirements. There are also questions about creating desktop shortcuts to automatically load and run specific .dat files with a program, and restoring old .dat backup files created by the XP Files and Settings Transfer Wizard on Windows 7. These threads reflect common user challenges with .dat file handling in Windows environments.
