Counter-Strike: SourceSource 1Supported legacy
SHORT ANSWER

The version anchor for Counter-Strike: Source is the “cstrike” game directory; server configuration is associated with “cstrike/cfg” where the engine uses a cfg subdirectory. User data and dedicated-server files may live in different Steam libraries, so resolve the live path from the running installation.

Before you change anything

  1. A legitimate Steam installation or dedicated-server installation for Counter-Strike: Source.
  2. A backup of every file that will be changed.
  3. Access to the local client console or the dedicated-server console, as appropriate.

Version-specific procedure

  1. Use Steam’s Browse installed files action for the client, or the service definition for a dedicated server.
  2. Confirm that the resolved tree contains the expected cstrike component.
  3. Distinguish client user configuration from server configuration before editing either.
  4. Write a harmless timestamped note to the intended backup directory, not to the live game tree, to confirm permissions.
  5. Record the absolute live and backup paths in the incident notes before collecting logs.

Verify the result

  1. The live path belongs to Counter-Strike: Source and contains cstrike.
  2. The server process owner can read the live files and write to its log directory.

Rollback

  1. No live file needs to change; remove only the harmless note from the backup directory.

Common pitfalls

  1. The same folder name can appear in client, dedicated-server, backup, and old-library trees.
