If you need to edit the PPSM file, one of the safest methods is to download and install the software dedicated to working with PPSM files. There are many tools known as PPSM Online Editors, but it is not certain that they operate in a way that keeps the data contained in the file safe.
Please note that not every program that supports PPSM will allow you to edit the file. Additional information about the PPSM file extension can be found here.
This is the best way. Choose one of the programs that support the PPSM file extension, open your file and check the editing options. It's safest to download the software from the developer's website. You will find links to the software developers' websites on the subpage of each program. Below you will find some examples of software programs that support the PPSM file (so it is very possible that they can edit files in PPSM format).
And here is the full list of programs supporting the PPSM file
Some file formats are just plain text files that you can open with Notepad. However, such manual editing of the PPSM file or any other file may result in damage to the file. If you make inappropriate changes and save the file, it may happen that you do not reopen the PPSM file.. For this reason, try to use software created to edit PPSM files.
It seems that one of the software on the list must be able to edit the PPSM files. Still not resolved your file editing issue? Try other solutions. Below we found websites that help in editing PPSM files.
