File Exists
Purpose
Search a folder for the presence of a file. If the file is found the workflow follows the ‘Exists’ path, otherwise the workflow follows the ‘Does Not Exist’ path.
This node can be used to change the flow of a workflow depending on whether a file exists.
Configuration
Filename
The name of the file that the system will look for. A specific filename such as ‘payments.txt’ can be used, alternatively wildcards can be used.
Wildcards
Standard * and ? wildcards are fully supported allowing you to copy all files matching a particular wildcard pattern.
The node can also use more advanced wildcards such as those based around ranges: […]
| Wildcard | Description | Example | Matches | Does not match |
|---|---|---|---|---|
| * | matches any number of characters | myfile.txt | myfile.txt or myfile.csv | myfile1.txt |
| ? | matches a single character | myfile?.txt | myfile1.txt | myfile22.txt |
| [abc] | matches one of the characters provided | [pf]ile.txt | file.txt, pile.txt | mile.txt |
| [a-z] | matches one character from the range provided | myfile[0-9].txt | myfile1.txt, myfile2.txt | myfile10.txt |
Additionally use can use the ! character to apply ‘not’ logic
| Wildcard | Description | Example | Matches | Does not match |
|---|---|---|---|---|
| [!abc] | matches one of the characters NOT provided | [pf]ile.txt | mile.txt | file.txt |
| [!a-z] | matches one character NOT from the range provided | myfile[0-9].txt | myfilea.txt, myfile22.txt | myfile1.txt |
