System.ArgumentException: File not Found

An error of the type shown below may result when exporting a large dataset (Crosstab, data table or report output) to Excel in the .xlsx format (not .xls, .csv or .txt).


System.ArgumentException: File not found: [Path]...


This process may be hitting an OutOfMemory exception, so the file is not created and the "file does not exist" error is displayed. To reduce the likelihood of this error:

If possible, when running reports, limit location and analyte selections.

Increase system RAM.

Run EQuIS as a 64-bit process.

Use Export to Text (instead of Excel) with the *.csv option. Exporting to *.csv uses far less memory and is much faster. Provided that Excel is the default program to open *.csv files, the file still opens in Excel.
