Split FileFile Tools

Break a large file into numbered parts that fit the destination.

Split File divides any source into predictable, sequential parts for upload limits, removable media, or constrained file systems. Choose the part size, receive a SHA-256 checksum sidecar, and keep the original file untouched so the set can be verified and joined later.

What it does

Split one or more large files into numbered parts with a verification checksum.

Split any file type without changing its contents.

Set an exact size or choose practical 10 MB, 25 MB, 100 MB, CD, or FAT32 presets.

Receive sequential .001, .002, and later parts that stay in order.

Create a SHA-256 sidecar for integrity checking during reassembly.

See the number of parts created instead of an ambiguous input-file count.

Reveal the output folder immediately while the source remains untouched.

Fit the destination

Choose the part size, preserve the source, and keep reassembly verifiable.

The original archive, practical size presets, numbered pieces, and SHA-256 checksum stay visible across one deliberate transfer workflow.

01

Split any file without changing its contents

Load a large archive, keep the source name visible, and choose the part size without converting or rewriting the original data.

02

Choose a destination-safe part size

Set an exact size or use practical presets for email, optical media, and FAT32, with numbered naming and checksum behavior disclosed before the split.

03

Leave with numbered parts and a verification checksum

See how many parts were created, confirm the SHA-256 sidecar, and reveal the output folder immediately while the original remains untouched.

Why it belongs

Why Split File earns a place in the toolbox.

The practical details that make this job faster, clearer, or safer than doing it by hand.

Fit the actual destination

Choose the limit that matters for an upload form, email handoff, optical disc, or FAT32 volume instead of estimating manually.

A set designed to reassemble

Foldout writes sequentially numbered parts and a SHA-256 sidecar so Join File can gather and verify the complete set later.

The result reports parts, not just sources

The completed state shows the number of parts created, source files processed, checksum status, and a direct reveal action.

How to use it

From opening the tool to saving the result.

  1. 01

    Add the file that needs to fit a smaller destination.

  2. 02

    Choose an exact part size or a practical preset.

  3. 03

    Run the split beside the original file.

  4. 04

    Review the part count and checksum, then reveal the output folder.
