How to get correct size of Rule-File-Binary (pdf)
I'm getting always 1-2 bytes more, when trying to get the file size of Rule-File-Binary (pdf).
I've uploaded a PDF file which is of size 80303 and with the tried solutions, I'm getting always 1 byte more
Tried solutions:
- @Default.Base64Decode(samplePDF.pyFileSource) -> 80304
-
String FilePath = myStepPage.getProperty("samplePDF.pyFilePath").toString();
PRFile afile = new PRFile(FilePath); // Create a PRFile object with path provided
long len=afile.length(); // get the length of the file
tools.putParamValue("FileSize", len); -> 80304 -
@String.length(@String.trim(samplePDF.pyFileSource)) * 3/4 -> 80304

You’re seeing the +1 byte because Rule-File-Binary stores pyFileSource as Base64 with a trailing newline (CR/LF) added during upload/export, so both Base64Decode and PRFile.length() include that extra line break. The fix is: decode to bytes, then trim any trailing CR/LF before counting. In a Java step: byte[] b = Base64Util.decodeToBytes(samplePDF.getString("pyFileSource")); int n = b.length; if(n>0 && (b[n-1]==10 || b[n-1]==13)){ n--; if(n>0 && b[n-1]==13) n--; } tools.putParamValue("FileSize", n);. If you can’t use Java, decode to a Binary Clipboard property and remove trailing 0x0A/0x0D in an activity loop, then read length. Also avoid len(base64)*3/4 because it ignores whitespace/padding; always compute from decoded bytes. If you need original file size for integrity, compare hashes instead of size, or capture size at upload time from the request headers.
