Expression |
([A-Z]:\\[^/:\*\?<>\|]+\.\w{2,6})|(\\{2}[^/:\*\?<>\|]+\.\w{2,6}) |
Description |
This regular expression pattern can be used to check the validity of paths for file upload controls. The uploaded file can be either stored locally or accessible through UNC. It cannot contain illegal characters for the windows OS - that may be supported e.g. on Mac OS – and cannot be a URL (Yes, as weird as it may seem, some users enter URLs in the file upload box, even though there is a browse button...) |
Matches |
C:\temp\this allows spaces\web.config | \\Andromeda\share\file name.123 |
Non-Matches |
tz:\temp\ fi*le?na:m<e>.doc | \\Andromeda\share\filename.a |

Comment:
This regex assumes the user is on Windows. I would highly recommend it NOT be used in a multiplatform/web environment.
