This issue affects Windows users. If you find file names are truncated with a tilde "~", e.g. "My_seque~.dna", then you have likely encountered a Windows-specific file path length limitation.
By default, Windows 11 restricts file paths to a maximum of 260 characters (MAX_PATH) to ensure backward compatibility with Win32 applications.
Files names may be truncated when saved if you have a deeply nested set of folders, usually with long names, such that the path limit is exceeded.
To fix this issue you have two options:
- Consult Microsoft documentation for instruction on how enable long paths in Windows 11. See https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?
- Shorten folder names to reduce the path length, and/or move the folder containing your files to a higher folder before working with and saving the file.
