# I turned on proxies in Shotcut, Kdenlive or Blender: where do the proxy files go, and does my saved project point at the original or the proxy?

Shotcut writes hash-named proxy files (with GoPro .LRV/DJI .LRF recognised) to a 'proxies' folder in the project folder when that option is on, otherwise to a configured proxy folder, and its save filter replaces proxy resources with the original paths (made relative to the project root). Kdenlive tracks each clip's proxy and original URL as clip properties and reuses an existing non-empty proxy unless asked to overwrite. Blender 5.2 by default stores proxies in a BL_proxy/<clip name> folder beside the original footage, or in a custom directory.

Curator qualifications: Code/docs read 2026-10-22; no editor run; no proxies generated. Shotcut save path (mltcontroller saveXML calling filterXML) not re-read; inferred from producer. Kdenlive proxy parameter details (proxyparams) not re-read.

Limitations: Code/docs read 2026-10-22; no editor run; no proxies generated.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
