File extension ppm is used for Portable Pixmap Format, a lowest common denominator color image file format.
PPM 24-bit color image that is formatted in text format. Each pixel is assigned a number from 0 to 65536 that defines the color of the pixel. Other information included in a PPM file includes the image height and width, whitespace data, and the maximum color value.
Because the PPM format is uncompressed and is inefficient compared to other image formats, it is seldom used for saving large image files.

Insight II is a comprehensive graphical molecular-modeling program from Accelrys Software, Inc. In this context, a PPM file is one of the data files used by the program.
The file contains saved proton chemical shifts for use in Insight II.
This format is associated with the Linux and Unix versions of Insight II and is a specialized, program-specific data format.
Open the file with Insight II on a compatible Linux or Unix system. Use Insight II's file-opening or import commands to load the saved proton chemical-shift data.
A PPM file is not normally converted to a general-purpose format because it stores Insight II-specific proton chemical-shift data. Use Insight II's own import or export functions when the data must be exchanged with another supported workflow.

Record marked as obsolete and not updated for a long time.
The Nokia post-programmable memory file format stores selected parts of firmware for Nokia mobile phones. PPM files commonly contain language data and are used together with other firmware components during phone servicing.
A PPM file is not a document or user data file. Specialized Nokia phone flashing or service software writes it to the phone's memory as part of a firmware update or repair process. The file must match the phone model and the rest of its firmware.
This format is obsolete and is no longer normally used with current mobile phones.
A PPM file is not intended to be opened or read as a normal document. Nokia phone servicing or flashing software can use it when installing compatible firmware on a supported Nokia phone.
Use only a PPM file intended for the exact phone model and firmware version. Installing an incompatible firmware component can make the phone unusable.
PPM files generally cannot be meaningfully converted to another file format. Their contents are firmware data intended for flashing, not content intended for export.
If a different language or firmware variant is needed, obtain the matching PPM file and flash it with compatible Nokia service software rather than converting the existing file.
