FT10 (.ft10)
.ft10 file signature | image/x-freehand
FT10 is a legacy FreeHand drawing file format originally developed by Macromedia and later maintained by Adobe after its acquisition of FreeHand. It was used to store vector illustrations, page layouts, and related graphic elements in FreeHand design workflows for print and digital artwork. As an older format, support is limited in modern software, but the files are generally safe to open because they typically contain static graphics rather than executable content.
