I want to use PPSS link text

According to the manual, PPSS should be used on a file system that supports file locking.

I assume that EXT3, EXT4, JFS, XFS, NTFS do support file locking, but I'm not sure. FAT16, FAT32, EXT2 probably don't support file locking but I like to be sure of that too.

Who uses FAT anymore? If you're still using it, time to update. Most systems that support EXT2 also support locking; only specialty and very old systems wouldn't. –  Chris S Oct 16 '10 at 14:30
    
Most linux "live" distro's can be put on an usb-stick. Most USB-sticks use the FAT fs by default and I wanted to be sure that PPSS runs on FAT/EXT2, as I plan on using it on such a live linux distro (Slax) –  user57330 Oct 16 '10 at 15:25

No filesystem supports locking at the physical level; all locking is done in the VFS. The ones to worry about are networked filesystems; NFS doesn't support locking unless the nfslock service is running, and other networked filesystems have their own way of handling (or not) locking.
