Special character support and file path restrictions

Unsupported characters are removed from file names and paths before delivering the files

Different destinations have different rules when it comes to support for special characters in file names and file paths. MASV avoids disruptions to transfers by removing special characters that are defined in general and destination-specific guidelines. Any file path metadata in MASV-generated package or sidecar files is updated accordingly. Please see the details below.

General file path specifications for MASV

When files are uploaded to MASV, the following file path issues are addressed by MASV, regardless of which integration is set as the destination:

  • Replace backslashes \  with forward slash /
  • Remove relative path indicators (to escape the working folder). Example:  ../ 
  • Remove leading and trailing / forward slashes. Example: /my/file.jpg/ becomes my/file.jpg.
  • Remove tabs and new line characters.

Supported characters and file path specifications for integrations

The guidelines below apply exclusively to files delivered to the specified integration.
