Exchanges two files on disk
Exchange Files [ Select ; Result (error) ; FilePath 1 ; FilePath 2 ;
Allow different Volumes ]
|Select entire contents||replaces the entire contents of a field with the result. If not checked the result replaces the currently selected portion of the field|
|Result (error)||an error code|
|FlePath 1||the path to the first file|
|FilePath 2||the path to the second file|
|Allow different volumes||allows the exchanging of files between different volumes (disks)|
Data type returned
The returned result is an error code. An error always starts with 2 dollars, followed by the error code. You should always check for errors. Returned error codes can be:
|0||no error||the files were exchanged|
|$$-43||fnfErr||one (or two) of the files not found|
|$$-1303||diffVolErr||the 2 files are on different volumes|
Other errors may be returned.
Troi File Plug-in 10.0
FileMaker Pro 16 to 17
You can use the Exchange Files step to quickly replace a file with an updated file.
When the step returns the error code $$-1303, you can use the checkbox Allow Different Volumes.
We assume that in your FileMaker file the following fields are defined:
gErrorCode Global, number gFilePath1 Global, text gFilePath2 Global, text
gFilePath1 and gFilePath2 should contain the path to existing files, for example “D:\Logs\Current.TXT” and
“D:\Work\Updated.TXT”. In a script add the following script steps:
Exchange Files [ $ErrorCode ; gFilePath1 ; gFilePath2 ] Set Field [ gErrorCode ; $ErrorCode // save the error code too ]
This will (quickly) exchange the two files. After this step the file “D:\Logs\Current.TXT” will have the contents of “D:\Work\Updated.TXT” and vice versa.
In a script add the following script stept:
Exchange Files [ $ErrorCode ; "Update Disk:NewData.fmp12" ; "Work Disk:DataDB.fmp12" ; Allow different volumes" ]
This will exchange the two files, even if the files are on two different volumes (disks).
