PDF Compressor may store temporary files during processing.
These files will be located in a subfolder "FX_PDF_Compressor" in the temporary folder for the user that controls the service account
The path of the temporary folder is specified by the following environment variables: TMP, TEMP or USERPROFILE.
If none of these variables is specified for the user or system, the Windows directory is used instead.
Alternatively, the environment variable FX_PDFCOMP_TMP maybe used to specify a temporary folder for PDF Compressor.
