The STO file is supported on 1 operating systems. Depending on your operating system, you may need different software to handle the STO files. Below is a summary of the number of programs that support and open the STO file on each system platform.
What is STO file?
The file in the STO format belongs to the 3D Image Files category. The creator of this file is Ecru Software. 3D Image Files consists of 622 similar files. PRO100 3D Interior Design Project is supported by 1 operating systems. The file will work on Windows systems, unfortunately not on others. The PRO100 application is recommended to open the file. It was released by ECRU s.c..
How to open STO file?
The main problem with PRO100 3D Interior Design Project is that the STO file is incorrectly associated with programs. This is manifested by the fact that STO files open in unusual applications or do not have an assigned program. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the STO 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 PRO100
An often overlooked issue is to make sure that PRO100 is installed on the computer. This can be achieved by typing PRO100 into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file STO with PRO100. Later in this article you will find a list of programs that can open STO files.
Programs to open STO file
Remember to download programs supporting STO files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of PRO100 with STO files
However, it may happen that the application itself does not cause the STO file to open in the PRO100 application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. 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. The "always use the selected program ..." field will set the PRO100 application as the default for handling the STO file.
Step 3. Update PRO100 to the latest version
If, despite the association of the PRO100 program with the PRO100 3D Interior Design Project file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the ECRU s.c. website and install the latest version.
Step 4. Check for the following problems with the STO file
Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:
The STO file may be unusually small compared to the original file. This is most often caused by a problem while downloading the STO file. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the STO file that we want to open. However, remember that not every infected STO 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 STO 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 this. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair STO file corruption. The easiest way to restore the file is from a backup or by contacting Ecru Software, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted file STO except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. If possible, you can try to move the STO file to another location.
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. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
