tmp files

About this tag
Tmp files are temporary files created by Windows and applications for various purposes, such as installation processes, software updates, or caching. Users often encounter .tmp files in folders like SysWOW64, the Windows installer directory, or game drives. While many are harmless and can be safely deleted, some may be associated with bloatware or even malware, as antivirus software sometimes flags them. Common examples include MSI-prefixed .tmp files that can cause high disk activity and system slowdowns. Understanding the source of these files helps determine whether they are safe to remove or require further investigation.
