Question

I am creating some files and file names are being fetched from database.

There is a file name called

CUA/ICOR Digital Collection.

But, because of forward slash, “CUA” is getting treated as directory.

I have found Forward slash in Java Regex

and I have tried:

String fileName = "CUA/ICOR Digital Collection";
fileName = fileName.replaceAll("/", "\\\\/");  // OP: CUA\/ICOR Digital Collection But No success

fileName = fileName.replaceAll("/", Matcher.quoteReplacement("\\/"));  // OP: CUA\/ICOR Digital Collection But No success

fileName = fileName.replaceAll("/", Matcher.quoteReplacement("\\\\/"));  // OP: CUA\\/ICOR Digital Collection But No success

File file = new File(exportPath, fileName + ".xls");

I am getting

File Not Found Exception At 'C:\export\CUA\ICOR Digital Collection.xls'

So, Now I doubt is it possible ?

On Windows, a file can’t contain /\:*?"<>|

You’re better off converting the / character to something like an underscore (_)
