Hi

I have a folder with many files. The file names start like 'd10-raw-LT-4000 ...' but the file names end with different charachters and formats.

I want to remove "raw-LT" from my all file names and rename them again. I do not want to change the rest of the name and other properties.

Use regexprep

FileName = 'd10-raw-LT-4000_xyz123.txt';
FileName = regexprep(FileName,'raw-LT-','');
% Output
FileName =
    'd10-4000_xyz123.txt'
    

To save the file, try:

FileName = 'd10-raw-LT-4000_xyz123.txt';
NewFileName = regexprep(FileName,'raw-LT-','');
movefile(FileName,NewFileName,'f'); % renames the file

Note: you must be in the current folder, or use the entire file path in the FileName.

Thanks Ruger

One error I got when one file doesnot meet the rule for file name.

I think I should use 'if'.
