Hi everybody,
my code accept just this format of String --> filename='"GComScan_20200115_135716.sdb"' (first and last Quotes are single) why i dont know ?
i have tried with this command to get that, but the result was reverse, means first and last Quotes are dobble " ' ' " (without space).
filename = "'" + string(extractBetween(filename, "Scans\\", filename(end)))+ "'"![quot.JPG](https://www.mathworks.com/matlabcentral/answers/uploaded_files/261926/image.jpeg)

filename = sprintf('"%s"',string(extractBetween(filename, "Scans\\", filename(end))));
Result:
filename2 = '"GComScan_20200115_135716.sd"'
Explanation:
filename is actually a character array, not a string (see Characters & Strings to understand the difference). The double quotes are part of the character vector. The outer single quotes are not part of the character vector; they actually define the variable as a character vector.
To see the actual content of the filename variable,
>> disp(filename)
"GComScan_20200115_135716.sd"

@Adam Danz sorry, yes, wrong answer, seems it was for another question, too much opened tabs in the browser.
Thats surprise, you've been in Tomsk, nice old city with a lot of students. I also have been there for a week, have made seminars for students, control systems with MATLAB. Amazing world.
