Filerr watches for file names that are not compatible with Windows computers, Windows formatted USB drives or online cloud services like Dropbox and Jungle Disk.

Mac OSX allows file names with characters that are not supported by Windows computers, Windows formatted USB drives or cloud services such as Dropbox and Jungle Disk. These file names include:

  • File names containing the characters / : * ? " |
  • File names beginning with space " "

Creating files with incompatible file names is unfortunately very common on the Mac, for example:

  • Dragging a Web page from Chrome, Firefox or Safari more...

Looks like the sun has set on this one, which is a pity. I don't know why it wasn't successful.
The developer link is broken- the domain "www.filerr.com" is parked.

Correct me if I´m wrong, but Filerr doesn´t seem to work with any other volume than the boot volume... at least all external volumes and containing folders are greyed out in Filerr. Since I only use my external volumes with other OS I´ll wait till Filerr works with all volumes you throw at it.

This is correct, Filerr will only work on your boot volume. The reason for this is that Mac OSX does not report file system events on drives other than the boot drive. Hopefully this will change in a future Mac OSX update.


Maybe you could add a feature that makes a manual scan possible... so you could scan an external volume on demand. I don´t need "real-time renaming" anyway, I´d prefer a thorough "manual scan" before I connect my external drive to a PC.


Thanks for the feedback. I'll definitely look into adding this to Filerr 1.1.
