Just now, I came to know that MSOffice will store two types of graphic formats in .rtf file.
- What I did was, I copied one image (Size: 66.6KB) to MSWord and saved the file as .doc.
- The .doc file size has become 89KB.
- Then I saved the file in .rtf format.
- The .rtf file size is 5075KB(4.9MB).
- I just searched for the cause then I found that .rtf format file will save this image twice.
- One in corresponding .GIF, .JPEG or .PNG and second format is WMF(Windows Meta File).
- That is the cause for drastic change in file size.
