Check does file exist in folder

JohnMcConalogue

I am writing a python script which deletes a file if it is present in a particular folder.

I want to be able to check if the file exists first, and if it exists I want to delete the file but if it doesn't exist I want to do nothing.

Anyone any ideas on this.

Thanks for the reply guys

A modification of Kevin's seemed to do the trick.

Just use Delete—Help | ArcGIS Desktop first thing. If the data set or file/folder exists, Delete takes care of business. If it doesn't exist, Delete still succeeds so there is no error to trap. The Result—Help | ArcGIS Desktop from Delete will include a warning if the file doesn't exist, but the operation still succeeds.

Use arcpy...

arcpy.Exists.... http://desktop.arcgis.com/en/arcmap/latest/analyze/arcpy-functions/exists.htm

then there is the whole arcpy.ListFeatureClasses, ListRasters, Listwhatever if you need things specific to geodatabases etc.

ie http://desktop.arcgis.com/en/arcmap/latest/analyze/arcpy-functions/listfeatureclasses.htm
