Nameglow, running
What Nameglow does
A folder of final_FINAL filenames takes too long to fix one file at a time. Drop it into Nameglow, choose a naming recipe and check the original and proposed names side by side before you rename.
For client handoffs, paste an old-name/new-name spreadsheet or import CSV or TSV. Nameglow matches by the original filename, so the row order does not matter. Resolve missing matches or conflicts, rename the batch and save a receipt of what changed.
What you can do
-
Use the spreadsheet you already have
Paste two columns from your spreadsheet, or import a CSV or TSV file. Nameglow checks for missing, duplicate and unknown names before you apply the mapping.
-
Save the rules you repeat
Combine a base name, find and replace, prefixes, suffixes, case, separators and numbering. Save the combination as a recipe for the next batch.
-
Preview before you rename
Read the original and proposed names together, and resolve filename conflicts before applying changes. Turn on Windows filename checks when preparing a cross-platform handoff.
-
Keep a receipt and an undo
Export an HTML preview or a receipt of the completed rename. Undo the most recent batch, including after relaunch. File contents and extensions stay intact.
