Q: How do I search for invalid file names using Treesize?

Open the Treesize File Search, enable only the " Advanced Search ", and define a filter on the right for " Name matches Regular Expression " and one of these patterns: [^[:print:]] if you want to treat all non-ASCII characters as invalid (which would e.g. also treat German umlauts as invalid) [^\P{C}] if you want to treat all non-printable Unicode characters as invalid It can also make sense to search for files containing the non-breakable space (Unicode NOBR U+00A0). To find them, use the pattern [\xA0] . To search for specific characters like percent and ampersand use the regular expression [&%] . You can find more examples on searching with regular expressions in the manual . You can get rid of unwanted characters using the bulk renamer of TreeSize .
