Freeupx For Win98se?

Hi! I have a Win98SE computer whose hard drive is almost maxed out. It is a FAT32 drive, so I can't compress it using DriveSpace or any other disk compression utility. I have UPX, so I can compress executables. I can create a batch file to do the job, add it to the context menu and use that to compress the files, but is there a better way? BTW, FreeUPX gave me an error stating that a required component is missing; I think it's incompatible with Win98SE.

 

Free UPX is not compatible with Windows 98.
Try UPX.

That explains it. I have UPX. Thank you!
