WINDOWS

Summary:

In Word for Windows 1.0, graphic images greater than 64K cannot be imported either through the Clipboard or by using the Insert Picture command. The 64K size limitation on importing graphics in this version of Word for Windows is imposed because it was released prior to the existence of Windows 3.0. The limitation itself is related to the upper boundaries of segment size in Windows versions 2.0, 2.03, 2.1, and 2.11.

The 64K limitation on graphic imports was removed in Word for Windows versions 1.1 and more recent versions when using Windows 3.0. The 64K limit remains when using Word for Windows 1.0 with Windows 3.0 or when using any version of Word for Windows with Windows 2.11 or earlier Windows releases.

More Information:

When a graphic file is imported, Word for Windows allocates a block of memory for the storage of this file in memory. Then, it translates the picture format to a metafile picture format and writes the metafile to disk as a temporary file. Once this conversion is complete, the memory block is freed, the temporary file is deleted, and the metafile is put into memory.
