What are the File and directory name length limits in Compression?

14 Aug 20261 minute to read

Syncfusion.Compression.dll can process paths that adhere to the traditional Windows path length limits: a fully qualified file name (including directories and file name) shorter than 260 characters, and a directory name shorter than 248 characters. If these limits are exceeded, a System.IO.PathTooLongException will be thrown.

Notes and guidance:

• The 260-character limit refers to the full path length (MAX_PATH) used by many Windows APIs.
• The 248-character limit applies to individual directory path components in some Windows APIs.

Example:

• Acceptable: C:\Projects\MyApp\data\file.txt (full path < 260 chars)
• Not acceptable: a fully-qualified path longer than 260 characters will likely cause System.IO.PathTooLongException when processed by Syncfusion.Compression.dll.
