.EDI,
.EDIF

SpDE's File-Import EDIF option.
.EDO
A SpDE (back annotation) DEIF file used to interface with various computer circuitry simulators.
edtp
Adobe Fetch PICT-based edition file format.
edtt

Electric Image
A graphic-image file format.
.EMF
Windows' Enhanced Metafile graphics file format
.EPS
Encapsulated PostScript file version intended to be "placed" or embedded within non-postscript documents.
EPSD
A structuring convention for Adobe PostScript files for enbeding EPS graphics inside other PostScript documents.
EPSF
Encapsulated PostScript File format for MacOS and DOS/Windows graphics. It supports: 2, 4, 16, 256, 32768, and 17 million colors or grayscale shades, with or without bitmaps, with TIFF or PICT previews. Files contain an EPS image in the data fork and usually an image preview in either the Data Fork or in the Resource Fork. (The graphics file's Data and Resource Forks contain information for reconstructing the file. Windows files only have Data Forks; MacOS files have both.
Typically when translating, if the file's Data Fork has pictures, its Resource Fork pictures, usually "thumbnails," may be ignored--test both for best output.) TIFF formatted previews are located in the Data Fork after the EPS image. PICT formatted previews are in the Resource Fork.
"Object" EPS images are more difficult to translate between applications and between operating systems than "Bitmaped" EPS images, particularly those created by an Adobe Photoshop™. "Vector" EPS images, such as those created by Adobe Illustrator, Aldus Freehand, and PostScript screen dump files are also difficult to convert. The best translations are those handled by the application itself and any relatives of it in other operating systems; such as, Freehand for MacOS to Freehand for Windows.
To reduce the size of files, some drawing and image-editing applications have the option to save bitmaps (BMP, PCX, TIFF, etc.) as "binary" data in EPS images. With binary data, the EPS image cannot be processed by the Windows PostScript driver--it is not printable.
To print, use the originating application to resave the image data as either "ASCII" or "Hex" rather than binary. If you cannot open the EPS image, try opening the preview image. Few applications will let you edit the spot colors of imported EPS images; usually changes are limited to converting spot colors to process colors. (If the EPS image has a B&W (1-bit) TIFF preview (typical of PC-created EPS) rather than a PICT preview (Mac only), then applied color will display on screen.)
EPS halftone images: decreasing the number of lines per inch (lpi) will result in a image having more shades of gray (graduated shades from white to black), but the image will become more grainy and less sharp; select "logarithmic" for smoother transitions between gradations of grays or "linear" for more distinct banding of each level of gray. EPS files use: EPS or EPSF for the file's Type code and filename extension.
.ERR
A SCS Design Entry Tools' Error file created during a consistency check of computer circuitry by either its Schematic Editor or Navigator circuitry simulator utilities
.EXE
Executable. An application program file containing code for using the data in the file, or in another command text or data file, or data loaded into RAM from BIOS ROM including hardware configurations.
If you change the name of the file, it, or a file requiring its code may not operate properly. For example, changing the name of DOS's PRINT.EXE file would affect an application's ability to print doucments.
This extension may also identify a self-executing application or self-extracting Zip file (document or application). MacOS: use a utility like SoftPC. or SoftWindows. The file has this creator type: PCXT and this File Type: PCFA.
