File Surveyor Lite is a free version of File Surveyor. File Surveyor Lite displays a summary of files by file extension. For each file extension, it displays the file type, the number of files, the total size of the files, the maximum and minimum file size, and the percent of the total size of all files in the scan. It will optionally include files in sub folders and will optionally include read-only files, hidden files, or system files. The results can be sorted and exported to a text or .csv file.
