How to open 1ST file?

The main problem with Readme Format is that the 1ST file is incorrectly associated with programs. This causes the file 1ST to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the 1ST 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 Windows Notepad

Programs to open 1ST file

Remember to download programs supporting 1ST files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Windows Notepad with 1ST files

If the application is or has been freshly installed, but the 1ST file still does not use the Windows Notepad program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the 1ST file with the Windows Notepad application.

Step 3. Update Windows Notepad to the latest version

The fault may also lie with the Windows Notepad program, it is possible that Readme Format requires a newer version of the program. Some applications allow you to update from the program level, and for others you need to download the installer from the Microsoft Corporation page and install.

Step 4. Check for the following problems with the 1ST file

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the 1ST file. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file 1ST or the program directory. However, remember that not every infected 1ST 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 1ST file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular 1ST file corruption. The easiest way is to restore the file from a backup, if there is one, or contact N/A
The program indicates that the file is encrypted or corrupted. The encrypted file 1ST 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.
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 1ST to a different directory.
This problem usually affects more complex files. In this case, the 1ST file is blocked by the first application to open it. Closing other programs should help. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the 1ST file for a certain period of time. If the problem persists, restart the machine.
