UiPath-ADAv1 Files, Folders, and Data Manipulation Practice Question
When writing data to a CSV file, which property should be set to true if you want to avoid overwriting existing data?
⚠ Common exam trap
Candidates often forget to check the 'Append' property, assuming write activities automatically preserve historical data instead of overwriting the entire file.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set 'Append' to true.
The 'Append' property in the 'Write CSV' activity is specifically designed for this purpose. By setting 'Append' to true, the automation adds new rows to the end of the file instead of clearing the existing content. This is essential for logging, audit trails, and batch data processing, where maintaining historical data is a critical business requirement that must be handled safely to avoid accidental data loss during export operations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set 'Overwrite' to false.
Why it's wrong here
There is no 'Overwrite' property in the standard 'Write CSV' activity. The correct property is 'Append'. Providing incorrect property names causes design-time validation errors, preventing the project from being built correctly. Developers must utilize the correct property names defined in the activity documentation for accurate configuration and reliable file output behavior.
- ✓
Set 'Append' to true.
Why this is correct
Setting 'Append' to true tells the activity to add the new data to the end of the existing file contents. This is the correct way to ensure that previous records are preserved during a data export process, fulfilling the requirement of maintaining a continuous data record without manual file manipulation.
- ✗
Set 'Create' to false.
Why it's wrong here
The 'Create' property controls whether the file is created if it does not exist, not whether existing data is overwritten. Disabling file creation would cause the automation to fail if the target file is missing, which is not the desired outcome for a data export task that should be robust and reliable.
- ✗
Set 'Delimiter' to 'New'.
Why it's wrong here
The 'Delimiter' property defines the character that separates values (e.g., comma, tab, semicolon) and has no impact on whether the file content is overwritten or appended. Configuring the delimiter incorrectly will corrupt the file format, making it unreadable by other applications, but it does not address the requirement of preserving data during writes.
