Finding Microsoft Office Temporary Files

Some Microsoft Office applications will create temporary files comprised of eight alphanumeric characters without a filename extension. Typically these are cleaned up by the application automatically, but various issues (such as network connectivity interruptions or anti-virus software poking its head in) can cause such files to be orphaned.

Isolating these types of temporary files for cleanup can be tricky. But the flexible FolderSizes search facility can do it with ease. Just click the Search button in the main FolderSizes application window, and select the FileName matching tab. Enable regular expression mode and enter the following pattern:

(\a\a\a\a\a\a\a\a)!.

The expression above matches exactly 8 alphanumeric characters with no extension, which is what many MS Office titles name certain temp files.

With FolderSizes, it’s also easy to find these files within a specific date range, size range, or even search by file owner.
