Detail

This article explains common scenarios that prohibit a data file (.edat/.emrg) from being opened or viewed properly. There are 2 common errors that users may receive.

Runtime Error

The following runtime error occurred:

Can not open data file. Check security permissions.

Line: 1899

Error Number: 75

This error occurs when running an experiment and refers to the Data File Name property found within the Experiment Object > Data File tab in E-Studio. This error can occur for the following reasons:

• The Data File Name is too long. The Data File Name, including the absolute path where the data file is written to exceeds Windows' MAX_PATH (e.g., C:\Users\USERNAME\Documents\My Experiments\3.0\Samples\BasicRT\BasicRT123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456.edat3). Please refer to the "Maximum Path Length Limitation" section in the attached .pdf.
• The Data File Name contains an invalid character. Refer to the "Naming Conventions" section in the attached .pdf.

NOTE: The attched .pdf is a document article from Microsoft's website about the rules of naming files and directories.

E-DataAid Dialogue

Cannot open file. Verify file is an E-Prime data file and is not already open or is not read only. Error Code: 0x80030005

NOTE: If the file is already open, a similar dialogue may appear as shown below.

The error messages shown above may occur even when an .edat or .emrg file is not open. Other common causes of this error include:

• Attempting to move or attach the file while it is already opened - the file should be closed beforehand.
• Opening from a ZIP folder - the file should be extracted from the ZIP before opening.
• Permissions error - the file has specific user permissions under the Security tab.

If the data file still throws these errors after correcting the causes above, the file is likely corrupted. However, if the Recovery .txt file exists, the E-Recovery application can likely be used to convert the Recovery .txt file into a new .edat file.

Apart from the error messages mentioned above, the .edat or .emrg file may open in an application other than E-DataAid. For example, the image below shows an example of where an .edat file opened in Notepad:

This typically ocurs when E-DataAid is not set as the default application to open .edat/.emrg files. To correct this issue, set the default apps by file type in Windows Settings to configure .edat and .emrg files to be opened with E-DataAid. If the E-Prime data file extensions cannot be mapped properly in Windows Setting, then the data file can still be opened by first launching E-DataAid, then selecting the Open option from the File menu, and finally navigating to the .edat or .emrg file.
