- STD files contain vector graphics, and can be used as a template to create new drawing files. STD files can be opened by OpenOffice.org Draw and Open Office Draw, which is a successor to StarOffice. STD files have been replaced by.OTG files, which support the OpenOffice document format for storing vector graphics. MIME type: application/vnd.
- How to open STD files. If you cannot open the STD file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports STD among those that are installed on your device. A very simple way to solve this problem is to find and download the appropriate application.

About File Extension STD. File.org aims to be the go-to resource for file type- and related software information. We spend countless hours researching various file formats and software that can open, convert, create or otherwise work with those files.

Defined in header |
std::FILE* fopen(constchar* filename, constchar* mode ); |
Opens a file indicated by filename and returns a file stream associated with that file. mode is used to determine the file access mode.
[edit]Parameters
| filename | - | file name to associate the file stream to | ||||||||||||||||||||||||||||||||||||||
| mode | - | null-terminated character string determining file access mode
|
[edit]Return value
If successful, returns a pointer to the object that controls the opened file stream, with both eof and error bits cleared. The stream is fully buffered unless filename refers to an interactive device.
Std Format
On error, returns a null pointer. POSIX requires that errno is set in this case.
[edit]Notes
The format of filename is implementation-defined, and does not necessarily refer to a file (e.g. it may be the console or another device accessible through filesystem API). On platforms that support them, filename may include absolute or relative filesystem path.
For portable directory and file naming, see C++ filesystem library or boost.filesystem

Do I have the right program?
If you don't have a program installed on your computer that's compatible with STD files, you won't be able to open one. See if you have one of the most common programs associated with STD files listed below.
- Unknown Apple II File
- StarOffice Drawing Template
- PROMT Document
- SureThing CD Labeler Document File
- Prosa State Transition Diagram Graphic
- Plug-in Acrobat Exchange
- STAAD.Pro Import/Export File for Steel FEA
- LocoScript Standard Script File
- OpenOffice.org Drawing Template
What type of file is it?
When you can't open STD files, try to figure out the file type. This can help you find the right program to open it. Usually, STD files are considered Vector Image Files. However, you can look up the file type to be sure. Start by right-clicking the file icon and clicking 'Properties' ('More Info' if you're on a Mac). Then look for the file type under 'Type of File' ('Kind' on a Mac).
Can a developer help?
When you can't open STD files, a software developer might be able to help. The developers for the programs mentioned above are as follows:
| Software | Developer |
|---|---|
| Unknown Apple II File | found on Golden Orchard Apple II CD Rom |
| StarOffice Drawing Template | Sun |
| PROMT Document | PROMT Ltd. |
| SureThing CD Labeler Document File | MicroVision Development Inc. |
| Prosa State Transition Diagram Graphic | Microsoft Developer |
| Plug-in Acrobat Exchange | PC Software Company |
| STAAD.Pro Import/Export File for Steel FEA | Research Engineers International |
| LocoScript Standard Script File | LocoScript Software |
| OpenOffice.org Drawing Template | OpenOffice.org |
What Can Open Stp Files
Try contacting one of these developers to find out how you can open your STD file.
Can I use a universal file viewer?
A universal file viewer is the way to go when you have STD files that can't be opened by any other program. Install a universal file viewer like File Magic (Download) and see if it will open your STD file. Remember that if your file is not compatible, the universal file viewer will only open it in binary format.
