How to open C1S file?

An often recurring problem with Photo Cache is that C1S is not associated with the correct program file. Thus, when you open C1S, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the C1S 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 Capture One

The first step is to check if the computer has the Capture One program installed. The easiest method is to use the system search engine by entering the program name Capture One in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file C1S with Capture One. Later in this article you will find a list of programs that can open C1S files.

Programs to open C1S file

Remember to download programs supporting C1S files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Capture One with C1S files

If the application is or has been freshly installed, but the C1S file still does not use the Capture One program, it means no association. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the C1S file with the Capture One application.

Step 3. Update Capture One to the latest version

If, despite the association of the Capture One program with the Photo Cache file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Phase One A/S website or update the program from the application.

Step 4. Check for the following problems with the C1S file

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. Usually this applies to C1S files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
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. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the C1S file that we want to open. However, remember that not every infected C1S 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 C1S 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.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair C1S file corruption. The easiest way is to restore the file from a backup, if there is one, or contact N/A
When reading, a message appears that the file was encrypted or corrupted. The encrypted C1S files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move C1S to a different directory.
This can happen on a file that does not support multiple access. In this case, the C1S file is blocked by the first application to open it. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the C1S file again. However, some background programs may block the C1S file while scanning. If nothing helps, please reset the device.
