What is SEP file?

The file in the SEP format belongs to the Raster Image Files category. Raster Image Files consists of 522 similar files. Separated Image Format is supported by 1 operating systems.

You can use XnView, FlowConnect in case PictView cannot be used.

How to open SEP file?

The main problem with Separated Image Format is that the SEP file is incorrectly associated with programs. This causes the file SEP to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the SEP file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install PictView

The first step is to check if the computer has the PictView program installed. The easiest method is to use the system search engine by entering the program name PictView in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open SEP files.

Programs to open SEP file

Remember to download programs supporting SEP files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of PictView with SEP files

However, it may happen that the application itself does not cause the SEP file to open in the PictView application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the SEP file with the PictView program.

Step 3. Update PictView to the latest version

If, however, after binding PictView with Separated Image Format there were still problems, you should update the program to the latest version.

Step 4. Check for the following problems with the SEP file

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

Very often, the file may be size 0 or incomplete. This suggests truncating the SEP file contents when downloading or copying. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the SEP file that we want to open. However, remember that not every infected SEP file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the SEP file. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular SEP file corruption.
The program can also signal the fact of encryption. The encrypted SEP files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move SEP to a different directory.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes you have to wait for the session to the file SEP to close. Some anti-virus or backup software may occupy the SEP file for a certain period of time. If the problem persists, restart the machine.
