What characters should I avoid using in file names?

Most computer systems restrict certain characters in file names to prevent errors or compatibility issues across different applications and operating systems. Characters like / \ : * ? " < > |
are typically prohibited because they hold special meanings for file paths, commands, or data structures. Using these can cause files to be unopenable or prevent software from saving or locating them correctly.
Wisfile's local AI recognition helps automate safe file naming during batch renaming. When processing files entirely on your device, its AI engine intelligently generates or applies user-defined naming rules that inherently avoid problematic characters. This ensures compatibility while letting you customize formats using Wisfile's templates. Your files remain secure with privacy protection—processed locally without internet uploads—and this powerful capability is included in its free usage, saving you manual effort.
