Problem:
Adding Valid Notes That TextMe Reports Are Invalid

Solution:
This commonly happens on disks which are swapped between Windows and MacOS.

To fix this, open the file in Notepad, delete the last two characters in the document. This includes any blank lines or spaces at the end of the file. Retype the characters if they are necessary.

Save the file and add it to the TextMe database.

This bug is caused by the way the file was created or modified, TextMe's method for opening text files and TextMe's safeguards against database corruption. This behaviour cannot be fixed in TextMe.

If a file can be opened in Notepad, it does not necessarily mean it is a valid note. Some examples of files like this are certain .reg files which contain Windows and driver related settings.

The only other way to add files which TextMe believes are corrupted is by opening them in Notepad, then dragging the text of the file into TextMe.
